China Indoor HV Isolation Switch Manufacturer, Supplier, Factory

SanGao high quality Zinc oxide lightning arrester It is a voltage and current protector with functions such as overcurrent, overvoltage, and undervoltage protection. When the current/voltage deviates from the set value, the relay automatically cuts off the power supply to prevent fire and protect electrical equipment. It also has an automatic reset function, which means that when the voltage and current return to normal values, the power supply will automatically recover.

SanGao advanced Cut out Fuse is equipped with standard fuse links, which can protect transformers, capacitors, cables or lines from short circuits and overloads in 11KV~38KV overhead distribution systems. If a short circuit occurs, the molten metal strip will melt, protecting electronic devices from overcurrent damage and internal electronic component operation errors. Fuses are widely used in power systems, electrical equipment, and household appliances. What's that? Fireworks in October? It's unlikely... more precisely, the bright blue flash you see on stormy and rainy nights is likely a fuse that protects the power grid.

SanGao durable 40.5KV Switch Recloser is used in 50Hz, 40.5KV AC three phase power systems for breaking and closing load currents, overload currents, and short circuit currents. When used in conjunction with an intelligent controller, it can achieve automatic reclosing function, as well as remote control, telemetry, remote signaling, and remote adjustment.

SanGao High Quality High Voltage Circuit Breaker is an outdoor distribution equipment with a rated voltage of 12kV and three-phase AC 50Hz. It is mainly used for breaking and closing load current, overload current, and short-circuit current in power systems.
