LuGao stands as a professional 12KV Outdoor Disconnecting Switch manufacturer.The "GW9-12" outdoor high-voltage isolator switch is designed for single-phase AC 50Hz high-voltage switchgear. This product is well-suited for power systems with a rated voltage of 10kV, specifically for making or breaking power supply under conditions of voltage and no-load. The isolator utilizes an isolated (disconnector) rod for operation.
Lugao is a excellent 12KV Outdoor Disconnecting Switch supplier.Our GN22-12 indoor high voltage disconnect switch is suitable for a rated voltage of 10KV, three-phase AC 50HZ in high-voltage switchgear within the power system, serving as a circuit breaker with voltage and no load. The switch features a novel, reasonable, and unique structure design. It adopts a two-step action locking method, providing excellent dynamic and thermal stability with low operating force. Utilizing epoxy resin, insulators, and brush-plated silver, along with other new materials and processes, the switch ensures good conductivity, compact size, and light weight. Its outgoing terminals easily connect with vacuum circuit breakers and oil circuit breakers, reducing the volume of switch cabinets, minimizing transition joints, and lowering costs.
