Metal Structures

Product description

The company produces transformer tanks for power and traction transformers made of steel and aluminum.
Beside mild steel and aluminum, the company also uses fine grained steel, non-magnetic materials and copper in the production of transformer tanks. All the above mentioned materials are successfully welded with the MMA, MIG, MAG, TIG and SAW welding procedures.Testing for leakage by means of pressure testing is carried out after the welding process, and also testing of the welding seam by means of non-destructive testing methods.
This type of structures is delivered to generator producers and producers of industrial, civil engineering and transport machines and equipment.Production process organization and handling of the material assure full traceability, and experienced engineers, certified welders and inspectors assure high quality of welded joints. Procedures attestation according to the Welding Procedures Specification (MAW, MAG and SAW) for structural steel of up to 250 mm thickness. Heat treatment in a furnace with numerically controlled process is performed after the welding process. Furnace dimensions are 7.5 m x 6.5 m x 3 m.
Company has 35 years of experience in designing and manufacturing of isolated phase busbars, with rated current of up to 16,000 A and insulation level of 24 kV, but also of segregated and non-segregated three-phase isolated busbars, with rated current of up to 6,000 A. The busbars are designed in conformity with the CEI recommendations (publication 298) and the ANSI (C37-23) standards. Each busbar is individually calculated and verified using the experience from numerous laboratory-type tests to be able to define the characteristics that are best suited for client's requirements. Temperature rising test is carried out on busbars with rated current from 2,000 up to 16,000 A. The bus is prefabricated in the factory in fully assembled sections.
