Switchgear and panel installation

Medium-voltage switchgear, ring main units, LV main distribution boards and capacitor banks, installed and commissioned.

Switchgear that protects the whole system

Switchboards control and protect every substation and network. A board with the wrong breaker or busbar rating, or with poor wiring, can take the whole site out of service at the first overload or short circuit.

We install medium-voltage switchgear designed to IEC 62271-200 and low-voltage assemblies to the IEC 61439 series, and we check the short-circuit rating against the network at the point of connection.

  • Withdrawable metal-clad MV switchgear
  • Ring main units (RMU) for compact and indoor substations
  • LV main distribution boards (MDB) and sub-boards
  • Motor control centres and capacitor banks

Frequently asked questions

RMU or withdrawable switchgear?
For a small substation with one transformer, an RMU takes less space and costs less. For large substations with several transformers and critical loads, withdrawable switchgear offers more flexibility and faster maintenance.
Why is a capacitor bank needed?
Motor loads lower the power factor. Where the tariff penalises a low power factor, a correctly sized capacitor bank reduces the electricity bill.
