Product Description
12kv Outdoor Dead Tank Sf6 Circuit Breaker with Spring Mechanism
ZW20-12 type outdoor high voltage AC SF6 circuit breaker is designed by our company as a circuit breaker sharing same cabinet. Its main use is to open, close load current, overload current and short circuit current in electrical system, and it is adaptable to protection and control function in substations and industrial and mining enterprises power distribution system, and also rural areas with frequent power grid operations. This switch use vacuum method to extinguish arc, SF6 gas to insulate, and overall sealing is good. Internal is filled with "zero" gauge pressure SF6 gas, no possibility of gas leakage, high reliability, and maintenance-free.
Flexible and convenient operation: this product can either use electricity to store energy, open and close using electricity, or store energy manually, open and close using hand, and can use remote control to operate with near distance and long distance;
Operation power factor small, high reliability;
Flexible installation method, can use hoisting on columns or sitting installation method;
Have maintenance free characteristic; circuit breaker main circuit, second side components, operation mechanism are sealed in SF6 gas (zero gauge pressure);
Not influenced by outside environment, stable performance, reliable and maintenance-free.
Reliable sealing performance, use mature sealing structure technique to ensure reliable sealing.
Incoming and outgoing insulation performance is good, use silicone rubber bushing to make insulation space between connection terminals abundant, and external insulation performance is excellent and safe to use.
