Northern Ireland Electricity Networks - Antrim Main


Product: SWR 12
Customer: Northern Ireland Electricity Networks
Location: Antrim
Installation: May 2016

Northern Ireland Electricity Networks sought manufacturers to supply and install four trial projects with retrofit circuit breakers, consisting of two South Wales Switchgear C4X switchboards and two Reyrolle LMT switchboards.


Hawker Siddeley Switchgear were one of two successful bidders, via a framework tender process, awarded the opportunity to supply and install retrofit circuit breakers. With Hawker Siddeley Switchgear offering the SWR 12.

The first trial project at Antrim Main Substation required Hawker Siddeley Switchgear to supply 9-off new SWR 12 circuit breakers. This trial project also required Hawker Siddeley Switchgear to supply new protection top boxes, equipped and wired to NIE Networks’ latest specification standards.

Employing the patented magnetic actuator technology with vacuum interrupters, the SWR 12 offers improved health and safety with the removal of oil and SF6; whilst also extending the life of the existing switchgear.
