This product is an LTK-40.5 indoor high-voltage AC SF6 circuit breaker, with smooth breaking performance, maximum parameters of 2500A-31.5kA, mechanical life of 10000 times, and switching back to back capacitor banks up to 1500A, which is at the leading level in China. It has been widely used in State Grid projects and has an absolute leading market share. Not only can it achieve no cutoff voltage and no heavy breakdown when switching capacitive loads such as capacitor banks, but it can also be applied to inductive load situations such as switching reactors and small inductive loads.
Main features:
Adopting an integrated spring mechanism with excellent performance, stability, and reliability.
The primary conductive circuit is installed in an insulation cylinder made of epoxy resin using APG process casting, effectively preventing external factors such as external force impact and polluted environment from affecting the arc extinguishing chamber.
The compressed air arc extinguishing structure prevents the circuit breaker from generating reignition and overvoltage during current opening and closing.
Equipped with a safety explosion-proof device, when abnormal situations occur, the explosion-proof device will automatically rupture, exhaust gas, prevent accidents from expanding, and ensure safety.
The handcart circuit breaker adopts a screw pushing mechanism, which is labor-saving, stable, and has good self-locking performance. It is equipped with KYN61 cabinet.
Specially used for switching capacitor banks (single or back to back), up to 1500A, which is the highest parameter in the same industry in China.
Forced air cooling required.
Manufacturing Time: 2 weeks.
