Product overview.
LW8-40.5 and LW8A-40.5 series sulfur hexaoxide circuit breakers are three-phase AC 50H outdoor high-voltage electrical equipment. They are suitable for the control and protection of 40.5KV power transmission and distribution systems. They can also be used as contact circuit breakers and switching electrical sets. This product can be equipped with CT14 spring mechanism. The circuit breaker complies with the requirements of the national standard GBI984-1989 "AC High-voltage Circuit Breaker" and the International Electrotechnical Commission standards IEC56 and IEC62270-100 "High-voltage AC Circuit Breaker"
The product has excellent breaking performance, uses a compressed air silencing chamber, has long electrical life, does not need to replace sulfur hexaoxide gas, has high mechanical reliability, long mechanical life, and can be operated frequently; each unit can be equipped with 6-12 current transformers for supply User choice. This product uses the new MKZ type SF6 pointer density gauge. The pressure gauge reading is not affected by temperature changes and is easy to use.
