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.
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.
