33KV Vacuum Circuit Breaker

Breaker Switch Unit with Encapsulated Vacuum Interrupter
Each 33kv automatic circuit recloser is embedded in a solid-insulated pole made
of weather-proof cyclo aliphatic epoxy resin. This enables a small design as
well as resistance against environmental effects.

The switch unit in vacuum type circuit breaker is comprised of three poles, the
operating mechanism, and the operating mechanism housing. The sequence of the
poles is A -B – C or 1 – 2 - 3 (sequence left to right when viewed from the
lower terminal side of the recloser switch unit.

Breaker Principle and Design of 36 kv vacuum circuit breaker
ZW32 series 33KV circuit breakers are used in distribution systems to make and
break normal and fault currents. 33kv outdoor vcb circuit breakers made by our
electric power equipment company are fully equipped with sensors and a
controller to provide a means of protection and control. In case of a line
fault, 33kv vacuum circuit breaker can break and make currents several times,
thus avoiding longer network interruptions due to temporary faults. The
manufacture, design, and testing of the vacuum recloser is based on current
standards IEC 62271-100.
