The XGN15-12 indoor metal enclosed switchgear is a compact indoor power supply and distribution unit. The ZN100-12 vacuum circuit breaker and XGN15-12 load switch of the XGN15-12 switchgear have the following advantages: strong insulation performance and convenient operation.
The interior of the indoor metal enclosed switchgear adopts a rotary fuse structure, which makes the replacement of the fuse highly convenient. The size of the XGN15-12 switchgear is extremely small compared to other gas insulation cabinets and it is eco-friendly power supply and distribution applications. This is particularly advantageous for urban users and in residential areas.
