The Structure Of Bolt Type Parallel Groove Clamp

parallel groove connector adopts plate-plate structure and is made of aluminum alloy. The connection is completed by fixing the connecting wire in the upper and lower grooved clamping plates with the tightening pressure of the bolts, and then transmitting it through flat washers and spring washers to provide a relatively uniform and constant pressure to the connecting wire. It can be disassembled after installation. It is often used in the jumper or ground wire overlap at the tension end of the line. In order to ensure that the wire clamp has sufficient and uniform pressure on the wire, aluminium pg clamp generally adopts a two-bolt or three-bolt structure. At the same time, it is required to tighten each bolt evenly during installation. Sometimes, in order to ensure operational reliability, two or three wire clamps are equidistantly connected during line construction. bimetal pg clamp The gripping force on the wire is about 10%-20% of the calculated breaking force of the wire.
blackburn parallel groove clamp Generally, only wires with the same diameter are connected. The allowed wire span generally includes two adjacent specifications. For example, burndy parallel groove clamp is applicable to wire cross-sections of 185mm2 and 240mm2, so a symmetrical design is adopted in the structure.
connector parallel groove allows wires with a certain diameter range to be connected in span combination. The structure adopts an asymmetrical design, and the pressure plate is designed to be adjustable left and right to ensure that both wires of different diameters can obtain relatively stable pressure when in contact. However, human factors have a greater impact on the tightness of the bolts.
