Product Features:
·Modular: The disconnector and vacuum circuit breaker are all arranged in three-phase independent solid-sealed poles, realizing a built-in disconnector.
·Stable performance: The vacuum arc-extinguishing chamber and direct-acting isolating knife are solid-sealed into one body. The relative positions of all components are guaranteed by molds, with high precision and no secondary assembly process. The overall electrical performance is stable.
·Deep integration: Based on the integration concept of complete switch integrated design and fusion technology, the bushing-type PT and CT are designed as part of the switch body. The measuring elements and switch elements are truly deeply integrated.
·Full sealing: The shell adopts aluminum alloy integral casting and CNC precision machining process, with water pressure resistance up to more than 0.24MPa; the disconnector, vacuum circuit breaker, CT and PT are all sealed in the aluminum die-cast box, and insulation is not affected by rain or condensation.
·Environmentally friendly: No harmful substances are emitted, no risk of gas leakage or explosion, and no need to consider the impact of harmful substances on the environment.
·Full insulation: The incoming and outgoing line terminals adopt silicone rubber external insulation bushings, which are not affected by outdoor accumulations causing phase-to-phase short-circuit faults.
·Environmental adaptability: Low-pressure dry air sealing, with no impact on insulation from low temperature, high altitude or humid environments.
·High reliability: Uniform electric field, small partial discharge of the entire switch, below 10pC.
·Mechanical life: 10000~20000 operations.
·Reliable corrosion protection: The operating mechanism and related transmission parts are all nickel-plated.
·Mechanism sealing: The operating mechanisms of the circuit breaker and disconnector are all sealed in the aluminum cast box.
