Application of IndoorsF6 Circuit Breaker SF6 circuit breakers are a perfect upgrade foraging power infrastructure,especially in situations where the insulation of motors and cables is sensitive to dielectric stress.Indoor SF6 circuit breakers.with their compact footprint and top-notch insulation performance,are right at home in space-constrained indoor substations and distribution rooms.They stand up well to frequent operation,ensuring the stable running of critical equipment and slashing maintenance downtime.Furthermore,their environmentally friendly characteristics make them an ideal fit for indoor locations with strict environmental requirements,helping to build a safer and more reliable power distribution network. LYHM4 medium voltage circuit breaker uses sulfur hexafluoride (SF6) gas as arc extinguishing and insulating medium. SF6 gas has smooth breaking characteristics, and there will be no interception phenomenon when breaking the current, and no operating overvoltage will occur. This excellent characteristic ensures that the circuit breaker has a long electrical life. And the impact on the equipment during operation, the dielectric level and thermal stress will not be affected.

VSG-C/12 type Side installation Indoor high voltage vacuum circuit breaker used spring to storage energy. The operating mechanism can be operated by two ways, by manual and electromotive operation, The characteristics is according with GB1984-2003 High Voltage AC Circuit Breaker, JB3855-1996 3.6-4.5KV Indoor AC High Voltage AC Circuit Breaker and IEC standard 62271-100:200162271-100:2001 High Voltage AC Circuit Breaker. VSG-12C indoor high-voltage side-mounted vacuum circuit breaker is an indoor and outdoor switchgear for 12kV power system. Loads of different natures, frequent operations, and occasions where short-circuit current is broken multiple times. The product adopts a new type of circuit breaker operating mechanism, and the primary part of VSG-12 can use international brand solid-sealed poles to seal the vacuum interrupter and the main conductive circuit parts into a whole to protect the interrupter from collision, dust and condensation.
