Product Overview
The HXGN□-12 air-insulated compact switchgear is switchgear developed by our company based on technical interpretation of power users' demands for reliability, safety and compactness of electrical equipment. It features air insulation, compactness, complete intellectual property rights and complete type tests. It is suitable for 10 kV/7.2 kV power distribution systems of public buildings, commercial residential buildings and industrial & manufacturing industries, and also for complete machinery driven by HV motors with high compactness requirements.
Product Features
Compact / flexible
Air-insulation mode meets the clearance and partial-discharge standards of the power industry technical specifications.
Compact cabinet dimensions, matching standard cabinet dimensions:
480*1000*1800 mm (W×D×H); the complete distribution system is especially compact, saving space for expensive urban building land.
Flexible busbar forms and extension methods facilitate splicing with other different cabinet types.
Integrated / solid-sealed
Integrated circuit-breaker combination design: the combination apparatus integrates the disconnector, circuit breaker, earthing switch and live sensor in one body, with modular design, simple and reliable interlocking and easy maintenance.
Visualized / high efficiency
Visualized disconnector break design, fast delivery, and overall modular design make assembly at electrical complete-equipment factories convenient and quick. The integrated structure realizes all interlock requirements within the single mechanism, reducing the risk of interlock failure caused by factory assembly process problems.
Stable / durable
Spring / permanent-magnet mechanisms optional, long mechanical life, solid-sealed vacuum interrupter packaging with dust protection and high insulation performance. The modular scheme combination enables the HXGN□-12 air-insulated compact switchgear to cover incoming, outgoing, ring-main and F-C circuit applications.
