GIS (Transformer) Terminal
The Ankura-YJZGG/YJZGGCB type dry-type GIS (transformer) terminal with rated voltage of 290/500kV (300/500kV) adopts a combined structure of pre-made stress cones and epoxy tubes. The spring clamping device presses the pre-made stress cones against the wall of the epoxy tubes, maintaining the pressure at the interface between the rubber stress cones and the cable insulation and the inner cavity of the epoxy tubes within a reliable range. It can adapt to the extreme high and low temperatures in domestic and international operating environments. The product has a compact structure, excellent performance, convenient installation, and simple maintenance. It has over fifteen years of operation experience and is reliable in performance.
Features
- There are two ways to connect conductors: crimping or plug-in type.
- Users can choose according to their needs.
- The product can be used for connecting GIS switches or transformers with cables. The connection method is either crimping or plug-in type structure, making the product installation more convenient.
- The product has extremely high reliability.
