MV Switchgears
12 KV / 36 KV Vaccum Circuit Breaker
The NUCON make Outdoor vacuum Switchgear Type PCVCB, is an outdoors, Structure mounted, easy to instal, vacuum s witchgera for use in 13/36 KV system. it is a porcelain-cald construction similar to conventional outdoor high voltage switchgear and is a gang operated triple pole circuit breaker fitted with reliable and well-proven vacuum interrupters. Adequate phase clearances and height have been provided to meet Standards and safety requirments. It is suitable for direct connection to overhead supply lines.

The type PCVCB design incorporates a minimum of moving parts and simplicity of assembly assuming a long mechanical and electrical life. All fundamental advantage due to use of vacuum interrupters like low drive energy, light weight construction, virtually shock free performance leading to ease of erection and reduction of foundation requirments etc. has been retained.

Suitability
The NUCON make PCVCB Vacuum switchgears are designed to handle all the switching duties that occur in primary distribution systems including rapid auto re-closing. The breakers are extremely reliable in service, require minimum space and have a long life expectance due to use of Vacuum interrupters. Moreover small size and weight, quiet and low vibration operation and high temperature sustainability enable the breakers to be used in hazardous locations.
