SF6 Ring Main Unit

DAYA SF6 Ring Main Unit Details

DAYASF6 Ring Main Unit  Parameters

PT or CT fails. SF6 ring main unit with distribution network automation interfaces is often equipped with PT and CT to provide data information such as switch operation power and load current required for distribution network automation. The poor quality of PT and CT provided by the manufacturer is the main cause.

Lightning arrester fails. Some lightning arresters in the SF6 ring main unit break down and explode, causing a short circuit between the cables in the room or the cable head discharges to the shell.

The operating mechanism fails. As the SF6 ring main unit in humid areas is not operated for a long time, the mechanism springs and auxiliary contacts of the control circuit switch are prone to rust.

Cable lap fails. Because the quality of the cable head itself and the construction technology are not good enough, especially when the large cross-section cable gradually releases the stress after installation.
