Description

SF6 Gas Insulated Metal Enclosed Switchgear

The ring main unit is to seal all the switchgear in a closed stainless steel box filled with SF6. There are no exposed live parts on the outside, and it is a fully enclosed and fully insulated switchgear, which is not affected by the external environment and operates safely and reliably. The ring main unit is divided into straight-through cabinets, circuit breaker cabinets, load switch cabinets, combined electrical cabinets, contact switch cabinets, metering cabinets and other standard units, which can be flexibly combined to achieve multiple solutions.

Features

Stainless steel metal shell, filled with SF6 gas as insulating medium, fully insulated and maintenance-free.

It has obvious visible disconnection points.

The chain is reliable and the operation is safe.
