Problem
Application Details
Leaking Transformer Fins
Wind Farm, UK
Lower edge of fins on oil filled transformer corroded and starting to leak. Problem caused by sheep rubbing against fins, damaging paint system.
Application was carried out in accordance with Belzona Know-How System Leaflet TCC-1. Pre-formed doubler plates were bonded over the corroded areas after manual surface preparation

Problem
Application Details
Leaking Transformer Flanges
Power Plant, West Tennessee USA
Leaking flanges created an environmental hazard and the transformer could not be drained for repair.
The application was carried out using a modified Belzona Know-How System Leaflet GSS-4, temporarily stopping the leak with Belzona1831 before encapsulating the flange with a Belzona 2000 series elastomer.

Leaking Switchgear Flanges
Electric Distributor, Australia
SF6 leaking through flanges due to failure of original mastic sealant
Following removal of the failed system by grit blasting, a Belzona 1000 series system was used to seal the flange joint.
Leak detection proved success of the repair and resulted in a further 515 flanges being sealed.
