Voltage connector COT 10-95

Voltage connector COT 10-95

Categories: ,


Code: COT 10-95 A    

The voltage connectors are permanently mounted on LV insulated overhead lines. They can be applied directly to the live insulated conductors using appropriate insulating tools without damaging of the insulation and the anticorrosive protection of the insulated conductor.

The voltage connector contains:
– an insulating piercing clamp SL 11.118 (Ensto)
– an insulated subassembly which allows a quick connection with the coupling plug of the short-circuiting device.
