Outdoor Vacuum Circuit Breaker

The 12kV intelligent high-voltage isolation switch is independently developed and manufactured by HUAJIDIAN. Designed to complement ZW8-12 and ZW32-12 pole-mounted vacuum circuit breakers, it features a visible isolation gap, intelligent remote electric operation, position feedback, and optional live-line indication. It is suitable for 10kV overhead line retrofitting, sectionalizing/branching applications, and smart grid upgrades in both urban and rural areas. Compared to traditional manual isolation switches, it integrates seamlessly with distribution automation systems, significantly reducing on-site operational risks and enhancing power supply reliability.

HUAJIDIAN’s 33kV pole-mounted vacuum circuit breaker is hailed as the "watchdog controller" of the medium-voltage distribution network industry. It is a core intelligent boundary switchgear specifically developed for the automation of urban and rural power grids, power supply for industrial and mining enterprises, and protection of residential distribution lines. The product utilizes advanced vacuum arc-extinguishing technology and integrated protection logic, combining overcurrent protection, zero-sequence earth-fault protection, undervoltage tripping, and reclosing functions. It supports both manual and electric operation as well as multi-channel remote communication.

The HUAJIDIAN 24kV Pole-Mounted Vacuum Circuit Breaker is a high-performance, maintenance-free outdoor distribution device designed specifically for the protection and control of medium-voltage power grids. Covering a rated voltage range of 12kV to 40.5kV, the product utilizes advanced vacuum arc-extinguishing technology, offering exceptional short-circuit breaking capabilities, an extended mechanical lifespan, and superior environmental adaptability.

The HUAJIDIAN 11kV Pole-Mounted Vacuum Circuit Breaker is a new generation of intelligent outdoor power distribution equipment designed to meet the upgrade requirements of smart grids; it is suitable for 12kV, three-phase AC 50Hz outdoor distribution networks. Equipped with a highly stable permanent magnet operating mechanism, the product integrates protection, measurement, control, and multi-mode communication functions. It offers advantages such as long mechanical life, high short-circuit breaking capacity, broad environmental adaptability, maintenance-free operation, and intelligent remote control. Capable of effectively isolating faults and restoring power supply, it is widely used in urban and rural power grids as well as industrial and mining enterprises, making it a preferred core component for distribution network automation upgrades.
