Product Description
DescriptionThe Unisun enjoy more than 16 year experience manufacture SF6 Ring main Unit in china, we import first APG line from Germany to localized air pressure guage production craft, our APG manufacturing including SF6 switch disconnector, embedded pole and etc epoxy resin insulation parts. iUN-panel units are used for the MV section in MV/LV transformer substations in public distribution systems and MV consumer or distribution substations up to 24 kV. FeatureThe iUN-panel range is made up of modular units containing metal-enclosed SF6 switchgear, using Sulphur hexafluoride (SF6) or vacuum:- switch-disconnector;
- Vacuum circuit breaker;
- Vacuum contactor;
- disconnector.
