copper parallel groove clamp ( parallel-groove connector):

1) used to link a bare conductor on an overhead line of equal nature

2) designed to connect two parallel conductors to tap a secondary line or to close a loop of one conductor to anchor it on an insulator

3) weather proof performance: having good performance after 1008 hours artificial climate aging test

4) righed grooves without any loose part

5) Circular arc embracing most of the area to provide the conductor uneasy creep and great grip strength
