Belzona® Keeps The Lights Burning



Power (POWR)



Valves, Pipes and Fittings (VPF)


Customer Location:

Power Station, Western Australia


Application Date:

July 2009


Application Situation:

Bushing of both blue and red phase of 330KV oil filled transformer. This is a major unit responsible for power supply to a major part of the city.



The seal around ceramic bushing had degraded allowing oil to leak out which in turn reduced the operational efficiency of the unit.



Belzona® 1161 (Super UW-Metal)



Ceramic and steel


Application Method:

Application was carried out in accordance with a modified version of Belzona Know-How System Leaflet VPF-11a. A vacuum was drawn on the unit to reduce/stem any oil leak. An MBX Bristle blaster was used to prepare the surface. Belzona® 1161 was used in conjunction with Belzona® 9341 (Reinforcement Tape) to seal over the leaking joints.


Belzona Facts:

There was a significant lead time in obtaining replacement bushing and the continuous filling of the existing bushing was both time consuming and expensive.
