Cable Accessories Aluminum Bolted-Ype Parallel Groove Pg Clamp

Description:
The parallel groove clamp is used for the connection of small and medium-sized aluminum stranded wires or steel-cored aluminum stranded wires and the steel stranded wires of overhead lightning conductors at positions that do not bear tension, and is also used for jumper connections of non-linear pole towers.

The bolt-type parallel-groove clamp is made of plate-plate structure and aluminum alloy material. The connecting wire is fixed in the upper and lower grooved splints by the tightening pressure of the bolt to complete the connection, and then passed through the flat washer and spring washer. Provide relatively uniform and constant pressure to the connecting wires. It can be disassembled after installation. It is often used at the jumper wire or ground wire lap at the strain-resistant end of the line. The clamp generally adopts a two-bolt or three-bolt structure, and at the same time, it is required to use even force when tightening each bolt during installation. Sometimes in order to ensure the reliability of operation, two or three clamps are equidistantly paralleled during line construction. The holding force of the bolt type parallel groove clamp to the wire is about 10%-20% of the calculated breaking force of the wire.
