Product overview

HXGN D-12 air-insulated compact switchgear, the switchgear developed by the company for the technical interpretation of power users' demand for the reliability, safety and compactness of electrical equipment. With air insulation, compact, complete intellectual property rights, perfect type test product characteristics. It is suitable for 10kV/7.2kv power distribution system in public buildings, commercial residential buildings, industrial and mining manufacturing industries, and also suitable for complete sets of mechanical equipment driven by high-voltage motors with high compact requirements.

products

Compact/Flexible

air as the medium meets the electrical clearance and local discharge standards of the technical specifications of the power industry.

compact matching cabinet size, matching standard cabinet size:

480*1000*1800mm (width x depth x height), the complete power distribution system is particularly compact, saving space for expensive urban construction land.

flexible bus form and expansion mode, convenient and other different cabinet type splicing O

Integral/solid seal

Integrated circuit breaker combination electrical design, combination electrical set isolation switch, circuit breaker, grounding switch, live sensor as a whole, modular design, interlocking is simple and reliable, easy maintenance.

Visualization/High Efficiency

visual isolation switch fracture design, rapid delivery time, the overall modular design, so that the electrical complete plant assembly convenient and fast. Integrated structure, all kinds of closure requirements are realized in a single mechanism, reducing the risk of locking failure caused by assembly process problems in the complete electrical plant.

stability/durability

spring/permanent magnet mechanism, long mechanical life, solid sealing vacuum interrupter package, dustproof, high insulation performance.
