High voltage sf6 gas circuit breaker
General
HR4 type high voltage indoor SF6 gas circuit breaker with two installation way by drawable/Fixed. which is widely application for three-phase AC power system of rated voltage from 3.3kV up to 36kV at frequency 50/60Hz, especially using for power plant, transformer substation, petrol chemical industry, metallurgy, manufacturing industry, airport, residential area, etc..
Its high performance switchgear which will reduce over-voltage and harmonic impulse at max for by a normal or fault breaking or making.
Its easy for interchange for VD4,SF1,HD4 type switchgear like type KYN28 or AMS, ABB type ZS1 series, etc.
This circuit breaker is follow per standards like:
IEC62271-100AC high voltage circuit breaker,
GB1984-2003 AC high voltage circuit breaker
JB3855 3.6-40.5Kv indoor AC High voltage circuit breaker
DL/T403 Specification of 12-40.5kV indoor High voltage vacuum circuit breaker.
