XH-12 Integrated electrical combination

Product technical features

◆Compact\Flexible:

◇Air is the medium of insulation, which meets the electrical clearance and partial 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.

◇The flexible busbar form and expansion method are convenient for splicing with other different cabinet types.

◆Overall\Solid Sealing:

◇Integrated circuit breaker combination electrical design, the combination electrical appliance integrates isolation switch, circuit breaker, grounding switch, and live sensor, modular design, simple and reliable interlocking, and convenient maintenance.

◆Visualization\High Efficiency:

◇Visual isolation switch fracture design, fast delivery time, and overall modular design make the electrical complete set of factory assembly convenient and fast. Integrated structure, all kinds of locks are required to be realized in a single mechanism, reducing the risk of lock failure caused by the assembly process of the complete set of electrical factories.

◆Stable\Durable:

◇Spring | permanent magnet mechanism is optional, long mechanical life, vacuum interrupter encapsulation by solid sealing, dustproof and high insulation performance. Product Specifications
