ZN63 (VS1) – 12 series solid-closure indoor high-voltage vacuum circuit breaker organically combined vacuum interrupter, mainelectric conduction circuit and insulation support and so on into an integrated embedded pole by adopting solid insulationstructure and using advanced epoxy solid technology for the first time. It successfully solves the problem of environmentaltolerance of vacuum circuit breakers from the root, to widen its application scope. The integrated embedded pole adopts thepatented technology of self-cross ventilation to cleverly solve the difficult heat dissipation problem brought by the solidinsulation structure.
Zn63 (VS1) – 12 series solid-closure indoor high-voltage vacuum circuit breaker is the first circuit breaker in China to realize themaintenance-free concept. The application of its long-life vacuum interrupter and epoxy pouring solid seal technology ensuresthe maintenance-free performance of integrated embedded pole. The matching high-reliability permanent magnet operatingmechanism guarantees the maintenance-free performance of operating mechanism. .
