Features
The shell refers to foreign advanced technology and is designed according to the actual situation. It has the characteristics of firmness, heat insulation and ventilation, good performance, dustproof, anti-small animal, moisture-proof, beautiful appearance and convenient maintenance. There are various options for housing materials. Such as: aluminum alloy plate, steel plate, composite plate, stainless steel plate, non-metallic material (glass fiber cement), etc.
The high-voltage side generally uses a load switch, but also a vacuum circuit breaker, and has a complete anti-misoperation function. Other ring network switchgear can also be selected. Transformers can be oil-immersed transformers, fully sealed transformers, or dry-type transformers. The substation has perfect protection performance, convenient operation, optional high and low voltage measurement, and can be equipped with automatic no-power compensation device according to user requirements.
The top cover of the box is designed as a double-layer structure, and the interlayer is filled with foam plastic, which has a good thermal insulation effect. The high and low voltage rooms are designed with independent top plates, and the transformer room is equipped with anti-condensation and automatic temperature control monitoring, heating and cooling devices.
The box body adopts natural ventilation, and forced ventilation equipment can also be installed. A dustproof device is installed on the outside of the door panel and the side panel corresponding to the shutter position.
