Splicing fitting: splicing sleeve, repair sleeve, parallel groove clamp:

Splicing fitting is used for splicing or repairing of conductor or ground wire of overhead transmission lines. The splicing fitting may be compression type, bolt type or preformed armor rods. Splicing fitting should meet all the mechanical and electrical performance of the conductor.

Splicing fitting types:
Splicing sleeve
Repair sleeve
Parallel groove clamp

Splicing fitting description:
Splicing sleeve is used to splice the conductor to keep its mechanical and electrical performance. The grip strength of the splicing sleeve should be not less than 95% of the conductor breaking strength.

Repair sleeve is used to repair damaged conductor in order to make it recover its mechanical and electrical performance.

Parallel groove clamp is used as the connector when middle or small section area aluminum or ACSR or ground wire is not bear tension strength. Parallel groove clamp can also be used as the jumper connection on non-linear tower. There are Cu-Al parallel groove clamp and Al-Al parallel groove clamp and other types.
