MV Solid Insulated Circuit Breaker
SIRING® series solid insulation switch modules, together with reliable, universal and modular breaker spring operating mechanism and three-station operating mechanism, constitute SIRING® series solid insulation switch units. The operating mechanism, which has passed the type test, is a mature and reliable product with many years of operation experience, and all its technical parameters meet the code requirements and the standards of electric power industry and power grids.
SIRING® Integrated Switch is made of three-position disconnector and vacuum circuit breaker by filling solid materials with new formula at one-time pouring. The primary circuit is completely enclosed in the new nano technology insulating materials without adding buffer materials and the static and dynamic contacts are not exposed to the air to avoid contact oxidation. Meanwhile, the surface insulation material of the switch body is continuously and reliably grounded, with the characteristics of full shielding, full insulation, full sealing, full grounding, dust-proof, waterproof and anti-condensation, which is suitable for the service environment under all working conditions.
