The bolt-type parallel groove Connectors is made of plate-plate structure and aluminum alloy material. Relying on the fastening pressure of the bolt, the connected

wire is 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 to the connecting wire. It can be disassembled after installation. It is often used at the jumper or ground wire lap joint at the strain

end of the line to ensure that the Connectors has sufficient and even pressure on the wire. The Connectors 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 Connectorss are connected

in parallel at equal intervals during line construction. The holding force of the bolt-type parallel groove Connectors to the wire is about 10%-20% of the calculated

breaking force of the wire.

Bolt-type equal-diameter parallel groove Connectorss generally only connect wires of the same diameter. The allowable wire span generally includes two adjacent

specifications. For example, the applicable wire cross-sections of JBL-4 parallel groove Connectorss are 185mm² and 240mm². Therefore, a symmetrical design is

adopted in the structure.

The bolt-type reducing diameter and groove Connectors allows continuous span combination of wires with a certain diameter range. The structure adopts an

asymmetrical design, and the pressure plate is designed to be adjustable from left to right to ensure that both different diameter wires can be contacted. A more

stable pressure is obtained, but human factors have a greater influence on the degree of bolt tightening.
