ISO standards are responsible for ordering the management of companies in different areas. Their compliance is voluntary, however, they are highly recognized internationally. These are standards and guidelines that seek to orient, coordinate, simplify and unify criteria in order to reduce costs and increase the effectiveness of companies, as well as to homogenize the characteristics and quality and safety parameters of products and services.

ISO 9001

ISO 9001 forms the basis for industry-specific standards. This document ensures the ability of organizations to adequately meet customer expectations. Achieving this involves implementing significant improvements in the efficiency of the entity, but also in the quality of the products, minimizing errors and increasing productivity.

By obtaining ISO 9001 certification, Delinte makes it clear that we are a stable competitor in the market. Our methods are based on the good quality of our products and our service, keeping us at the forefront of our sector with efficient management rules and the adoption of continuous improvements.

ISO 9001 certification is very important to ensure the proper functioning of companies, SMEs and organizations of all types. However, welded fabrication companies have specific certification systems, due to the fact that it is essential to have certain technical knowledge and experience to guarantee the quality of the welding work, which must be evaluated before, during and after the process.

EN 15085 certification

EN 15085 is composed of a series of standards of the European Committee for Standardization, which includes criteria for the production, overhaul and maintenance of railway vehicles and parts and the welded fabrication of metal materials intended for this purpose. This standard demonstrates that Mecanizados Delinte has total control over the welding processes, producing parts that fully meet the quality expectations of our customers.

Not only are quality controls performed on the final product, but controls are established at the beginning of the product design, followed by the selection of the main materials and appropriate consumables. In addition, the personnel who will participate in the welding must have the documents proving their professionalism.

EN 15085, which determines the appropriate quality conditions based on the fusion welding method, is accepted in virtually every country in the world, including the United States and China.

Since 2015, in DELINTE we materialized this commitment to quality by obtaining ISO 9001:2008 certification and EN 15085-CL2 certification for the welding of metal structures for the railway sector, which distinguishes us in terms of quality in the welding process.

In Mecadelinte we specialize in the manufacture of metal electrical cabinets and racks for the control of the trains that are installed inside.

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.
