OUR SOLUTIONS IMPLEMENTED

Transmit electrical energy from a transformer substation equipped with two 5,500 V contactor feeder circuits. These network feeders supply watertight step-down transformers installed in underground pit. The power supply is configured as two half-loops to ensure system reliability. The 5,500 V cable (3x1x25 mm² cross-section) supplies all the network transformers.

MATERIAL USED

  • One cell with two 5,500 V contactor feeders,

  • 10 watertight, IP68-rated TER transformers, ranging from 10 kVA to 32 kVA, 5,500 V / 400 V.

CUSTOMER BENEFITS

Centralised power supply from only one substation

Watertight (IP68) and corrosion resistant transformers

5500 V network cross-section cable 3x1x25 mm²
