Belzona® 2211 Seals Oil Leaks On Switch Relays

 
 

Industry:

Power (POWR)

 
 

Application:

Mechanical Power Transmission (MPT)

 
 

Customer Location:

Electricity Distribution, Western Australia

 
 

Application Date:

1998

 
 

Application Situation:

Earth bushings on an oil filled switching unit

 
 

Problem:

Up to five litres of oil per day were leaking through the bushings. Full repairs, working inside the reactor were deemed to contravene their Duty of Care, so alternatives were sought.

 
 

Products:

Belzona® 2211 (MP Hi-Build Elastomer)

 

Substrate:

Steel and porcelain

 
 

Application Method:

Application was carried out by encapsulating and sealing the leaking bushing to the surrounding metal. A jack between roof and bushing top was used to stem leak by compressing against cork gasket while the Belzona application is completed.

 
 

Belzona Facts:

The repair was completed in 12 hours and cost just 6% of the quoted price to effect a full repair, that in any case could not be carried out for health and safety reasons.
