Porcelain Clad High Voltage Vacuum Circuit Breaker UL 145kv SF6

Porcelain Clad 145kv SF6 High Voltage Vacuum Circuit Breaker UL

General of Porcelain Clad 145kv SF6 High Voltage Vacuum Circuit Breaker UL
LW36-145 type outdoor AC HV porcelain SF6 circuit breaker is applied in power system with 50Hz frequency, 110kV system normal voltage. It is the main power equipment used in power plant and substation for control and protection.
LW36-145 type outdoor AC HV porcelain SF6 circuit breaker is equipped with CT type spring operation mechanism and three phase mechanical linkage operation.
LW36- 145 type outdoor AC HV porcelain SF6 circuit breaker is filled with SF6 gas with well arc-extinguishing and electric insulation performance. Double-circle O type seal ring is used for preventing leakage effectively.
LW36-145 type outdoor AC HV porcelain SF6 circuit breaker is a new type of high voltage SF6 circuit breaker with high performance, which is designed according to national standards and combine domestic industry made technic. The main features are as follows:

• High breaking level, break reliably when outgoing terminal is in short circuit, out of phase and fault in near zone.
• Structure of arc-extinguishing chamber is simple, reliable and convenient to maintain.
• Long service life, have 16 times' breaking ability under full capacity and free of maintenance under normal operation in 10 years.
• Light operation force, adopts compact spring operation mechanism with simple and reliable.
  Rated charging pressure of gas is low and hard to fluidify in low temperature.
• Small occupied area
• Low noise level and suitable to apply in residential area
• Long overhaul period and less maintenance.
• Short installation time on the spot
• Reliable and safe operation as well as convenient maintenance
