High Voltage Switchgear
- 1Application of domestic and foreign circuit breaker with high reliability and long life span.
- 2Consideration of electrical and mechanical stability with engineering design.
- 3Economical products with easy maintenance.
- 4Preservation of long life span with excellent blockage and input trait of circuit breaker and steadfast operating devices.
- 5With the excellent insulation restoration trait during the electric current blockage under high degree of vacuum state, its Arc period is less than 15ms.
- 6There is no lowering of the vacuum level and abrasion in the joints even with the long-term use of vacuum circuit breaker. It is excellent in blockage capacity has long mechanical life span.
