Introduction of SF6 Ring Main Unit

The SF6 ring main unit seals all the charged components (load switch, grounding switch, busbar, etc.) used in a SF6 stainless steel metal box filled with a certain pressure, and is insulated with SF6 gas. The arc extinguishing medium, operating structure, and fuse are still in the air, which is convenient for maintenance and replacement. The incoming and outgoing wires are connected to the cable through the cable terminal, and the cable head is touchable and has no exposed live parts. A pressure relief valve is installed on the back or lower part of the switchgear to ensure the safety of the operator in case of extreme failure.

Its structure is more compact, its size is smaller, and its performance is more secure and reliable. And because it is completely sealed, it is not affected by dust, condensation or even flooding during operation, and can be used in most areas of our country.
