Our solutions implemented
After a technical audit and taking into account the needs and imperatives, we proposed the establishment of:
Distribute electricity in 5.5 kV from a substation equipped with 2 transformers
– 1.6 MVA and 10 kV/5.5 kV.
The switchboard, with 6 feeder contactors
supplies the watertight step-down transformers installed in pits, close to the lamps.
Power supply of transformers with 5.5 kV 3c x 25 mm² cable
The whole installation can be supplied from one of the two transformers.
- A 5500V switchboard containing two isolating switches, one bus coupler and six feeder contactors 5500 V,
- 32 transformers TED TTT 16 kVA 5500 V / 400 V,
- 4 transformers TEH TTT 50 kVA 5500 V / 400 V,
- 8 transformers TEH TTT 100 kVA 5500 V / 400 V.
