Product Description

 

 

Description
LW8-40.5, LW8A-40.5 series sulfur hexafluoride circuit breakers are three-phase AC 50Hz outdoor high-voltage electrical equipment,suitable for the control and protection of 40.5kV transmission and distribution system, can also be used for connection circuit breakers and open and close capacitor Banks. The product can be used with CT14 spring mechanism. The circuit breaker conforms to the national standard GB1984 -- 1989 AC high-voltage circuit breaker and the international electrotechnical commission standard IEC56, IEC6220-100 high-voltage ac circuit breaker.
The product has excellent breaking performance, USES the pressure air type arc extinguishing chamber, the electric life is long, does not replace the sulfur hexafluoride gas, the mechanical reliability is high, the mechanical life is long, can operate
frequently; Each set can be equipped with 6-12 current transformers for user's choice. This product adopts the new MKZ model SF6 pointer density meter, the pressure gauge reading is not affected by the temperature change, easy to use.
