Product Description

Liugao is a 15KV Indoor Type Disconnector Switch supplier.GN22-12 indoor high-voltage disconnect switch is suitable for a rated voltage of 10kV, three-phase AC 50Hz, and is utilized in high-voltage switchgear within the power system as a circuit breaker under voltage conditions with no load. The switch features a novel, reasonable, and unique structural design. It employs a two-step action locking method, providing excellent dynamic and thermal stability with low operating force. The use of epoxy resin, insulators, and silver-plated brushes, along with new materials and processes, ensures good conductivity, compact size, and light weight. The outgoing terminals facilitate easy connection with vacuum circuit breakers and oil circuit breakers, reducing the volume of switch cabinets, minimizing transition joints, and lowering costs.
