Product Description
Aluminium Alloy Bolted Type Parallel Groove PG Clamp
Description:
The bolted-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.
The bolted type parallel groove clamps generally only connect wires of the same diameter, and the allowable wire span generally includes two adjacent specifications. For example, the applicable conductor cross-sections of JB-4 parallel-groove clamps are 185mm2 and 240mm2. Therefore, a symmetrical design is adopted in the structure.
The bolted type parallel groove clamps allow continuous cross-diameter combination of wires within a certain diameter range. The structure adopts an asymmetrical design, and the pressure plate is designed to be adjustable left and right to ensure that the two different-diameter wires can be connected when they are in contact. A more stable pressure is obtained, but human factors have a great influence on the tightening degree of the bolts.
