Bolted Type PG Clamp

Description

The bolt-type PG clamp is made of plate-plate structure and aluminum alloy material. Relying on the tightening pressure of bolts, the connected wires are fixed in the upper and lower grooved splints to complete the connection, and then transmitted through flat washers and spring washers. Provides a relatively uniform and constant pressure effect on the connecting wires. It can be disassembled after installation. It is often used at the jumper or ground wire lap joints at the strain end of the line. In order to ensure that the clamp has sufficient and even pressure on the wire, it is grooved. The bolt-type PG clamp generally adopts a two-bolt or three-bolt structure, and the installation requires uniform force when tightening the bolts. Sometimes in order to ensure the reliability of operation, two or three clamps are connected in parallel at equal intervals during line construction. The holding force of the bolt-type PG clamp to the wire is about 10%-20% of the calculated breaking force of the wire.
