630A Sf6 Gas Insulated Indoor Switch Disconnector for Medium Voltage Uniswitch Switchgear
Warmly wecome to Send us any enquiries anytime"
Product Description
GSC-36 high voltage SF6 load circuit breaker, with a rated voltage of 36kV, can respond and protect the power system in case of errors. The switch can be manually operated or electrically operated, with optional grounding function. The combination of switch and fuse can protect the entire system. The rated current of the fuse can be determined according to customer requirements. This switch is compact in size, easy to install, maintenance free, and suitable for a wide range of applications, especially circular hosts. It can also be used in conjunction with vacuum circuit breakers to achieve excellent performance and favorable cost.

Features
The load switch adopts double break rotating moving contacts and has the following three states: Closing;Opening; Grounding.
Good insulation performance. The load switch uses SF6 as the arc extinguishing and insulation medium. The switch is sealed by upper and lower shells cast with epoxy resin.
Good safety performance. If an arc occurs inside, a structural weakness at the rear of the casing will burst, and the arc exhaust valve on the cabinet will open, directing the overpressure airflow to the outside of the cabinet.
It can be operated manually or electrically, making it easy and reliable to operate.
Three phase integrated installation, good periodicity, few parts, easy to adjust and install, simple and easy to implement, long service life.
Each load switch is sealed and maintenance free for life.
