Fully insulated ring network cabinet

Fully insulated ring network cabinet is a group of transmission and distribution electrical equipment (high voltage switchgear) installed in a completely enclosed metal or non-metal insulated cabinet, or made into an assembled spaced ring network power supply unit. Its core part adopts load switches and fuses, which have the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution stations and box-type substations in load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises.

The main features of the fully insulated ring network cabinet include good sealing, heat resistance, corrosion resistance, excellent insulation performance, long service life, safety and reliability, etc. It is suitable for operation in high altitude, high temperature, humid and other environments, and is one of the important equipment in the power grid. In the ring network cabinet, SF6 gas is usually used as the insulating medium. This gas has excellent insulation performance and strong arc extinguishing ability, which can ensure the operation stability of high-voltage electrical appliances.
