Prefabricated Metal Transformer Substation

The range of MV/LV metal substations is designed to meet all transformer substation applications for public or private distribution.

They may contain the following materials:

– transformers from 100 to 1250 kVA

– MV switchboards from 1 to 4 cells

– automation

– LV switchboards and other equipment… These substations can be personalized and configured taking into account the installation constraints.

Functional test: according to IEC 62 271-202 §6.2.3;
Roof load test: according to IEC 62 271-202 §5.4.2;
IK 10 protection test: according to IEC 62 271-202 §6.7.3;
IP 23D degree of protection test: according to IEC 62 271-202 §6.6 and IEC 60 529

Advantages

Reduced weight and dimensions;

Post 3 times lighter than a concrete post: < 5 T
Reduced dimensions for optimal transport in container

No maintenance

Reinforced corrosion resistance thanks to its aluminum casing and its galvanized frame;
Compatible with tropical environments

Natural roof ventilation

Double skin option (upper skin and lower skin) allowing natural ventilation of the roof and limiting the effects of sunshine on the internal heating of the substation.

Limitation of dust ingress into the substation

• As an option, the MV and LV compartments can be partitioned in order to guarantee an IP 54 degree of protection.

Adaptation to customer needs

Transformers (voltage, connection, etc.) suitable for all market segments;
Medium Voltage switchgear available in 24 or 36 kV, in modular or compact version.
Public (TIPI, TRX) or private (TGBT, DGBT) LV distribution boards

Quick and easy commissioning

No specific means or tools required for lifting the station. This is systematically delivered with a lost spreader.
– Substation weight in 1250 kVA version 24 kV = 5T
Civil engineering limited to a single concrete slab.
