Belzona® Repairs High Voltage Breaker

Industry:

Power (POWR)

Application:

Customer Location:

New England, USA

Application Date:

Summer 2010

Application Situation:

SF6 High Voltage Breaker.

Problem:

The aluminum casting on a SF6 High Voltage Breaker cracked, causing coolant to leak out and create a dangerous operating situation. Dismounting and replacing the breaker was not an option as no spare breaker was available for months.

Products:

Belzona 1111 (Super Metal)

Substrate:

Cast Aluminum

Application Method:

The surface preparation was carried out with a hand tool grinder and the application was done in accordance with Belzona Know-How System Leaflet TCC-1.

Belzona Facts:

Outages are scheduled months in advance and require Grid operator approval. The station was in a scheduled outage when the leak was discovered. No replacement was immediately available so Belzona 1111 was used to get the plant back on-line on schedule, thus saving thousands of dollars.
