China Manufacturer Supply Outdoor High Voltage SF6 Circuit Breaker FW36-126

Product Description

Outdoor High Voltage Sf6 Circuit Breaker Model Lw36-126
Outdoor high voltage SF6 circuit breaker type LW36-126 is used as control and protective equipment as well as connecting circuit breaker in electric power system of 126kV, AC 50Hz. 
The SF6 interrupter is of one break construction for each phase and a single post which, adopts the quen-ching principle of auto-expansion and equipped with spring operation mechanism of CT motor energy storing, with three phases being connected electrically. 
The procuct tallies with the standards of GB 1984 and IEC 62271-100. 

Main Features: 
1. Auto expension interrupter with better interrupting characteristics; 
2. Long electrical endurance design and higher insula-ting property; 
3. Reliable in mechanical property and less maintenance; 
4. Low noise; 
5. Simple in erection, adjustment and test; 
6. Reliable in sealing; 
7. Long mechanical life and long maintenance period; 
8. Safe and reliable in operation.
