Steel cabinets used for power converters, battery storage or HVAC applications for all types of railway vehicles: tram, metro, regional ( EMU, DMU) high speed and locomotive. Assembled by welding acc EN 15085 CL1, riveted, bonded and powder painted complying EN 45545 HL7.
Substations are transformer or distribution centers made of sheet steel in desired dimensions. They are suitable for use of all types of MV switchgears and LV panels. They are manufactured in the requirement number of sections and doors according to the project design. Strong construction made of sheet steel and profiles is painted with electrostatic powder paint or liquid paint for high corrosion resistance.
In order to prevent the strong solar radiation in hot summer, the shell can be equipped with heat insulation material with low thermal conductivity, the most used fillers are: rock wool board, polystyrene foam, etc.
Modular design in requested depth, width and length, in average 4 times lighter than a concrete version along with easy transport and commissioning are just some of the advantages of this solution. Compact substations are suitable for residential quarters, urban public utilities, renewable power plants, power distribution etc
The outdoor cabinet is meant to being used in railway industry and is designed to withstand different environmental conditions, the micro climate inside the cabinet being achieved in accordance with the operational environmental temperature and humidity (specified by the customer). The micro climate inside the cabinet is preserved at the required level required by the customer via the heating management units (heaters for temperatures below 10°C and/or fans, integrated air/ air heat exchanges for temperatures above 25°C).
The 400/230 Vac and 48…220Vdc auxiliary services cabinets are designated to supply the low voltage consumers within the 110/20(6)kV transformer substations of the power supply and distribution companies: Electrica SA, CEZ Group, ENEL Group, E.ON Group; Transelectrica’s 400/220/110kV connection and transformer substations; hydro power plants; thermal power plants.
Own contrivance product, the DISMOD board is the optimal solution in electrical distribution, automation, motor control and protection for all industrial applications, infrastructure, commercial and residential buildings. All type-test assemblies (TTA) have been successfully achieved at the panel testing in an independent testing laboratory in Romania. A tested product offers the guarantee for a tested technical solution, an optimal internal architecture, continuous functioning of the served installation under conditions of maximum safety and the possibility of further expansion with minimal changes.
The Electroalfa primary distribution switchgear are designed for 7,2 and 24 kV rated voltages and rated currents up to 4000 A. Compliant with the technical standards of nationwide power generation, transport and distribution companies such as Transelectrica (the national transmission operator), CEZ Group, E.ON Group, Electrica Group (area distribution operators).
The Electroalfa switchgear for primary distribution, of the S 12xx range, for a maximum voltage of 12KV c.a., have been tested for values of the continuous rated current of up to 5,000A and values of the rated peak withstand current of 50 KA/ 1s. This type of gear withstands the action of the internal electric arc, with a classification index of up to IAC AFLR 50KA, 1s. The switchgear from the range of S 24xx, for a voltage of 24 KV c.a. have been tested for values of the continuous rated current current of up to 2.500A and values of the rated peak withstand current of 25 KA/ 1s.
The medium voltage switchgear with double bar system is designed for the primary distribution on the medium voltage part of transformation stations from the power distribution systems and combines the new technologies with the existing infrastructure.
The medium voltage switchgear with double bar system is an indoor electrical equipment, in metallic compartments cabinet, with insulation in the air, being formed of a vacuum breaker and air bar separator.
