IEC SEPARABLE CONNECTORS / 42 KV / 1250 A
Chardon Front T-Body / Coupling (Rear) T-Body connectors are fully
screened and fully submersible, products are used to terminate polymeric
cable to dead front apparatus such as transformers, switchgear, and other
equipment. They can be use at 36kV and 42 kV. Products can be used for
indoor or outdoor applications, and are able to be used for all polymeric cable
types ( XLPE, ETP, etc.) with copper or aluminum conductors. The design is
especially suited for the harsh off-shore wind farm environment where long
runs and large cable are needed.
