Product descriptions from the supplier
Description
470 structural design:
The length of the outgoing pole is 470mm, designed specifically for connecting GIS equipment and transformers, suitable for fully enclosed composite electrical appliances (GIS) or oil immersed transformers
Adopting a spring compression stress cone structure, pre compressed on the conical wall of the epoxy sleeve to avoid poor contact caused by aging of the stress cone
Electrical performance:
The rated voltage covers 66kV~138kV, suitable for cable cross-sections of 240~2500mm ² (66kV) or 240~2500mm ² (110kV)
Fully dry structure, no need for insulation casting agent, eliminates the risk of oil leakage, local discharge capacity ≤ 5pC
