Belzona® Keeps The Lights Burning

 
 

Industry:

Power (POWR)

 
 

Application:

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.

 
 

Problem:

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

 
 

Products:

Belzona® 1161 (Super UW-Metal)

 

Substrate:

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.
