GIS / Transformer Terminal
The Ankura-YJZGG/YJZGGCB type dry-type insulation GIS (transformer) terminals with rated voltages of 48/66kV, 64/110kV, 76/138kV, 127/220kV, 290/500kV (300/500kV) adopt a combined structure of pre-made stress cones and epoxy sleeves. The spring clamping device presses the pre-made stress cones against the wall of the epoxy sleeve, maintaining the pressure between the rubber stress cone and the cable insulation and the inner cavity of the epoxy sleeve within a reliable range, which 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.
- 48/66kV, 64/110kV, 76/138kV, 127/220kV conductor connection in two ways: crimping, plug-in type.
- Users can choose according to their needs.
- The product can be used for the connection of transformers and cables, with a plug-in structure for connection, making the product installation more convenient.
- The product has extremely high electrical sociality and reliability.
