220kV CB Head Overhaul

July 1, 2015

Following on from the 220KV CB head replacement at Haywards substation, PBA were engaged to carry out a major overhaul of the removed CB heads to enable Transpower to keep these as serviceable spares.

PBA liaised with Transpower to organise delivery of the heads and advised of the required components, as the overhaul includes replacing the major integral components.   Once reassembled, a full range of tests and checks were carried out to confirm correct operation and serviceable condition.  The heads were then wrapped, suitably packaged and delivered to Transpower stores, ready to be called on for the next planned outage.
