OUR SOLUTIONS IMPLEMENTED

Creation of one 630 kVA 400 V / 55,00 V step-up substation with 7 contactor departures. The 5,500 V / 400 V watertight step-down transformers are powered using a small cross-section cable, 3×10 mm². The transformers are installed in pits or rooms at the base of the lighting masts.

MATERIAL USED

One 5,500 V cells with one arrival switch and seven network contactors, 9 watertight transformers, TER single phase transformer for three phase network, 5,500 V / 230 V; 5 or 10 kVA, 22 watertight transformers, TER three phase transformer for three phase network, 25 kVA 5,500 V / 400 V, One step-down watertight transformer 160 kVA 5,500 V / 400 V.

CUSTOMER BENEFITS

Watertight (IP68) and corrosion resistant transformers

Small cable cross-section reduces costs

Centralised power supply from only one substation
