Model NO. | 66-138 kV GIS cable terminal transformer terminal (757 structure) |
Rated voltage | 110kV |
Series | YJZGG |
757 Structural Design:
Adopting a plug-in fully sealed structure, the top fittings are pre cast into the epoxy sleeve without the need for sealing rings, completely solving the top sealing problem
Built in spring compression stress cone, matched with epoxy sleeve cone wall to avoid poor contact caused by aging of stress cone
Electrical performance:
Rated voltage covering 66kV~138kV, suitable for cable cross-section of 185~1600mm ², short-circuit current withstand capacity ≥ 25kA/s
Fully dry design, no need for insulation casting agent, eliminates the risk of oil leakage, suitable for internal installation of GIS equipment
