Tension Clamps And Wedge Clamps

When using insulated wires, the selection of line dead end clamp
In densely populated, tree-filled, and polluted areas, we are increasingly using insulated wires to replace bare wires.
Compared with bare wires, it has the advantages of high safety and reliability, reduced line loss, and less wire corrosion. When using insulated wires, we need to pay attention to the fact that since ab cable dead end clamp is clamped on the outer diameter of the "wire" rather than the outer diameter of the "conductor" when used, the abc dead end clamp model used should be selected based on the outer diameter of the wire rather than the outer diameter of the conductor. For example, in the power line, JKLGYJ-150/8 steel core reinforced cross-linked polyethylene insulated overhead cable is used. After calculation, it is known that its conductor outer diameter is 15.30mm, plus its insulation thickness of 3.4mm and conductor shielding thickness of 0.5mm, it can be known that its conductor outer diameter is 23.1 mm. According to the above table, the 4 it should use is NLL dead end clamp for ab cable-5. If we select the equipment wire clamp based on the conductor outer diameter of 15.30mm at this time, then the selected equipment wire clamp cannot be used.
In addition, we must tighten the screws evenly when installing dead end clamp for abc cable, and require that there is no increase in wire stress at the contact surface between the installed wire and the original metal, so as to prevent the wire from being damaged by breeze vibration or other wire oscillation conditions and ensure that the grip force of fungsi dead end clamp on the wire is not less than 95% of the wire breaking force.
