Outdoor Isolation Switch
SanGao High Quality Outdoor Isolation Switch is a high-performance 12kV AC metal armored switchgear designed specifically for power distribution systems. The device adopts a pull-out structure and complies with GB 3906 and IEC 62271-200 standards. It is suitable for substations, industrial plants, commercial buildings, and renewable energy facilities, with excellent reliability, safety, and intelligent control functions, and can be used for distribution, protection, and management.
Zinc Oxide Lightning Arrester
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.
Outdoor Boundary Vacuum Circuit Breaker
SanGao High Quality Outdoor Boundary Vacuum Circuit Breaker is an outdoor power distribution device with a rated voltage of 12KV and three-phase AC 50Hz. When the internal fault of the user occurs in the T-shaped connection of the 12KV distribution line, or although it occurs inside the user's incoming switch, the protection action time limit and improper protection of the substation's outgoing switch can cause the outgoing protection of the substation to disconnect.
