Access control, the first security measure

We are specialists in the manufacture of access control cabinets that are characterized by their finish and high precision. Our products adapt to any type of company, purpose and size. The purpose of access control systems is none other than to grant permission for authorized persons to enter a building, office or warehouse.

Virtually all companies need to control the people accessing the inside of their facilities. In this sense, technology has made it possible to create electronic access systems. Physical security is often one of the main reasons for the need to install such controls. Most companies or organizations use different levels of access control depending on security levels, from access to property to that involving entry into specific areas. Devices including mechanical, electrical or biometric systems are installed for this purpose.

In general, we can say that access control devices will be installed at all entrances and exits. An important aspect is the durability of these controls. In this sense, at Delinte we are not only capable of manufacturing any prototype that is proposed to us, but we always use the best materials.

We manufacture the structures of the access control cabinets in galvanized steel or stainless steel. We rely on the fact that these materials offer the necessary resistance to atmospheric agents and also to possible acts of vandalism. In any case, we ensure that all our access control cabinets use materials that have passed the most rigorous tests for resistance to water, dust and, especially, the corrosive maritime environment.

But among our functions is also the realization of other types of equipment such as auxiliary equipment for tunnels, toll parking, road signs, etc.

Control of the number of people, essential

Controlling the number of people entering a certain space, be it a parking lot or a public show, has always been very important, but today with the pandemic it has become essential. In this sense, control systems that use the emission of ticktes are among the most widely used. Our cabinets are specifically designed to house both the hardware and software required to perform these functions.

In this regard, it is very important to be able to guarantee the continuous operation of the machines for as long as possible, regardless of the weather and the atmospheric factors they have to face.

At Mecanizados Delinte we have been specializing for more than 30 years in providing our customers with the best possible solutions. We sit down with them to get to know their ideas and needs in order to develop the prototypes they need. Designs that our professionals then manufacture with care, taking care of all the details, from the quality of the materials to all the processes inherent to the work.

At Delinte we strive to ensure that both the service provided and the product manufactured meet our customers’ expectations. To this end, we continually strive to maintain and update our technical resources. And in the appropriate selection of our suppliers by means of objective criteria for the evaluation of their products and/or services.

Both TIG and MIG are acronyms. MIG stands for Metal Inert Gas, while TIG stands for Tungsten Inert Gas. Let’s take a closer look at what each of them consists of.

TIG welding

It is one of the types of welding that is becoming widespread today, especially in stainless steels, because although it is more expensive, it offers better finishes. One of its advantages is that this process is very clean, leaving hardly any residue on the base metal.

But the great advantage of TIG welding is that it allows very precise temperature control, which is ideal for penetrating thick steels and for jobs requiring a high level of precision.

The finishes obtained with this system are very strong, precise and corrosion resistant. In addition, they are homogeneous and allow a completely smooth result to be obtained. TIG welding also offers the option of using a filler metal or not.

MIG welding

MIG welding is also known as gas and metal arc welding. The arc is formed from a continuous wire electrode and the parts to be joined, and is protected from the surrounding atmosphere by an inert gas.

MIG welding offers a number of advantages among which we can highlight that it allows welding in all positions. Also perform precision welds from 0.7 to 6 mm without preparing the edges and offering very good finishes. It is a process that offers high productivity and provides good quality.

In Europe, the gas most commonly used in this type of welding is argon. In the United States, on the other hand, helium is the most widely used. When welding steel, argon must be mixed with oxygen, since quantities greater than 5% of pure argon produce bites.

Three different MIG welding processes can be distinguished. Semi-automatic is the most common. Here the welder sets parameters such as voltage and current, which are then automatically maintained by the equipment as the welder drags the gun. Then there are the automatic and robotized processes. The latter is mainly used on an industrial scale.

Delinte’s workers are experts in precision TIG and MIG welding and are qualified to weld carbon steel, stainless steel and aluminum from 1 to 9 mm thick. We are ISO 9001:2008 certified. In fact, we are in the process of adapting to ISO 9001:2015 and we have the UNE 15085-CL2 certification required for the welding process of equipment and components in the railway sector.

Do not hesitate to ask us for a quotation for any of our products you are interested in, from a metal electrical cabinet to a shelter type cabin.

Traffic is regulated in different ways, through agents, traffic lights, various signals, time and parking restrictions, the use of reversible lanes, etc. Signaling becomes a fundamental part of traffic control, helping to regulate traffic and make it as safe as possible.

Its function is to guide the driver at all times, indicating the difficulties he will encounter along the way and giving him the necessary guidelines to overcome them successfully. Safe circulation must be based on the principles of safety, fluidity, comfort, economy and non-pollution.

But signaling and control require sturdy, secure structures that stay in place to do their job properly.

In machining
Delinte
we have been a reference in the construction of access control cabinets for more than 30 years. The necessary software is installed in them so that everything works correctly and at the same time they are always connected to the control panel, which can make decisions and modifications when necessary.

Types of cabinets

• Roadside video surveillance cabinets are becoming essential for speed controls.
• The function of the SOS lockers is to provide access to safety equipment when an emergency arises on the road, especially in conflict zones such as tunnels. They allow users to communicate with the control center personnel.
• The gauging cabinets help to control access to certain spaces such as hospitals, parking lots, etc., being an excellent support for security control and video surveillance.

The advance of technology coupled with urban development, including of course traffic control, means that we are moving towards the concept of smart city. In this sense, we are also working on the creation of innovative products that allow us to adequately protect the hardware and software that is so necessary for the proper functioning of the different aspects of these cities.

All the cabinets and frames that we manufacture at Delinte comply with the UNE-15085-CL2 standard, which guarantees that they have passed the certification and quality requirements for the welding manufacturer that performs new construction or repair (maintenance) work on railway vehicles and their components.

The regulation affects ATEX enclosures individually, but not only. The detailed guidelines result in the evaluation of all components as well. This is because of the seriousness of an explosion in the workplace. For this reason, special care is taken to ensure that they do not come into contact with particularly susceptible substances or materials.

Possibility of explosion

Explosive atmospheres are defined as those in which there is a mixture of flammable substances in the form of gases, vapors or dusts in the air. Under these conditions, when ignition of these substances occurs, the total propagation of combustion is triggered. They are present in a large number of industries, from agriculture and livestock to timber and chemicals, to give just a few examples.

For an explosion to occur, several conditions must be met simultaneously, such as the mixture of combustible substances with the oxygen present in the air in the precise proportion that creates an explosive atmosphere and that this is in contact with a source of ignition.

It is clear that in this type of atmosphere it is very important that arcing and sparks that may occur due to failures or perhaps misuse of the instrumentation be avoided. separated as far as possible from explosive atmospheresor minimize their contact to the point of avoiding ignition.

Protection in ATEX atmospheres

Directive 2014/34/EU (ATEX 95), which came into force on April 20, 2016, defines the specifications for the equipment and use of electrical and non-electrical equipment in an explosive atmosphere. A classification scheme sets out the essential requirements on safety and health protection for equipment.

All equipment installed in an ATEX zone must be protected against the risk of explosion. The equipment in these zones, such as the ATEX cabinet, must be certified by an organization approved for this purpose in accordance with the aforementioned directive. The certification consists of a specific marking of the product category and the area and atmosphere in which it can be used.

ATEX cabinets are certified as components. They are combined with other ATEX components (electrical, pneumatic, hydraulic, etc.) to form a final solution that must be ATEX certified.

All the ATEX cabinets that we manufacture at
Mecanizados Delinte
comply with the required standards of protection against the risk of explosion. We manufacture cabinets in galvanized sheet metal or stainless steel for the analysis of liquids or gases in ATEX zones. These products can be SAM enclosures, ATEX or pressurized enclosures. They can be heated or insulated with rock wool and meet IP or NEMA standards.

Our company has the technical capacity to create prototypes and industrial metal developments to achieve unique parts for any industrial sector, especially electrical metal cabinets.

We could say that the first electric train was the one designed by Werner Von Siemens in 1879 in Berlin. In Spain, the first electrified line is considered to be the Gergal- Santa Fe (Almería) section, which was inaugurated in 1911.

Electrical circuit of the trains

The electrical circuit is responsible for supplying power to the trains. It consists of a series of installations that are in charge of adapting the electricity and the correct operation of the motors, in addition to ensuring that electricity reaches the train from the installations along its entire length.

Trains demand a high power of electricity, we are talking about voltages ranging from 1500 to 3000 Vdc. Originally, the trains had their own power plants, but this was expensive and impractical once power plants began to operate close to urban centers. Even so, it is necessary to convert the high voltage energy with the one that needs to be injected to the catenary, for this purpose there are the substations.

There are two ways for trains to capture electricity, through an electrified third rail, a system used in Germany and other parts of the world. Or through an overhead contact line, called catenary, the system used in Spain. The train or tramway accesses electricity through the friction of the trolley or pantograph located in the power car. Catenaries can be powered with both direct and alternating current.

Train motors are in charge of converting electrical energy into mechanical traction, which is, after all, what produces the movement of the railroad. The motors and the equipment that make their operation possible are installed in the power car.

Finally, the return circuit is the one that facilitates the return of the energy used by the motors back to the substation.

Safety systems

Of course, the circuit is equipped with a series of safety systems that cut off the electricity supply if any anomaly is detected. The main safety systems are located in the substations, which automatically check for problems up to three times. If confirmed, power is suspended until the maintenance team fixes the error.

Extra-fast circuit breakers are the safety system installed on the train itself. In this case, it is up to the driver to reset them if they jump. Of course, lightning conductors are installed along the substations and the catenary.

At Delinte we are specialists in the installation of metallic electrical cabinets and racks for train control. They are installed inside and comply with the UNE-15085-CL2 standard in which Delinte is certified for aluminum, stainless steel and carbon steel constructions.

For this reason, almost all major cities have vehicle counting systems and some essential elements to regulate traffic to try to make it as smooth as possible: traffic lights.

Traffic lights are fixed signaling elements consisting of three lights: red, amber and green according to color conventions, through which traffic flow is regulated. On December 9, 1868, the first traffic light was installed in London following the design of John Peake Knight. It needed a policeman to activate it. Until relatively recently, traffic lights regulating traffic at intersections followed fixed patterns.

Today, thanks to technological advances, most cities have implemented variable-action traffic light systems that regulate the timing according to the traffic density at any given moment.

The traffic light system in large cities

We must understand that traffic lights in a city do not act in isolation, but are connected to a large network that is controlled from a central office. From this location, the correct operation of the traffic light network and the general traffic conditions in each area of the town is regulated, and the user can interact with the different equipment at any time to change the programming if necessary.

The entire network of traffic lights in the cities is connected to monitoring software, so that if there is damage at an intersection, the control center receives an alarm that pinpoints the location of the problem. At each intersection where there are traffic lights there is a local controller, which is a kind of electronic programmer that coordinates the traffic lights at the respective intersection. It is the real control brain of the intersection, in charge of deciding the timing according to traffic volumes, pedestrians or predetermined parameters calculated on the basis of traffic studies.

The controllers are equipped with a control card where the programming of the intersection is recorded and also have software that allows connection to the central computer. Obviously, installing this equipment at street level means that it must be located in a secure space that allows it to be protected from atmospheric agents and vandalism. Delinte has been a reference company in the construction of road signaling cabinets for more than 30 years. In fact, lately we are also specializing in cabinets for SMART-CITIES management and control. Our cabinets are made of galvanized steel or stainless steel and have passed the most rigorous tests for resistance to water, dust and maritime environment.

Electrical metal cabinets and access control cabinets are some of the products most demanded by the companies we work for. To contact us simply call 916 77 03 64 or fill out the form on our website and we will contact you to inform you and provide you with the appropriate budget.

Thanks to the electrical panels, the possible risks of overloading the electrical network are minimized and short circuits are avoided. That is why it is very important that all panels are equipped with protection switches that automatically shut down the power supply in case of electrical accidents.

In an electrical panel there are different types of switches, each one with a specific function within the installation. Switches, in turn, are usually organized into different types of blocks.

In order to be able to safely handle the installations and machinery as well as the respective equipment in the electrical cabinet, it is necessary to have the means to electrically isolate the power and control circuits from the general power supply network.

This function, which is called switching, is carried out by different specific devices such as disconnectors or switch disconnectors and switching functions integrated in multi-function devices.

All types of receivers can suffer electrical accidents, either by overvoltage, fall, short-circuits, etc,. or mechanical type, such as rotor draft, overloading, etc. To prevent these accidents from damaging components or disturbing the power supply network, starters must include protection systems against short circuits and overloads. This is in addition to specific devices such as fuse disconnectors, circuit breakers, protection relays and measuring relays, as well as specific functions integrated in the multi-function devices. All these elements are integrated in the motor center cabinets.

Specialists in the manufacture of customized electrical panels.

In DELINTE we specialize in the manufacture of metallic electrical panels for high, medium and low voltage. We have the capacity to make series of large number of units as in the case of some of our main customers and, of course, they are cabinets designed and manufactured following the indications and requirements of each customer.
