Anti arc puncture clip (CFH)

● Purpose

A protective device to prevent lightning strikes and wire breakage of overhead insulated wires, suitable for copper and aluminum overhead insulated wires.

● Performance parameters

1. Lightning full wave impulse withstand voltage (peak) kV: 100

2. 1-minute power frequency withstand voltage (effective value) kV: 50

3. Power frequency arc current (effective value) kA: 12.5

4. The puncture site is coated with a unique waterproof insulation paste

● Installation instructions

This product is installed on the load side of the line insulator.

◆ Puncture type thread clamping method:

1. The tightening method of aluminum alloy torque nut: parallel the insulated wire into the wire clamp groove, first tighten the torque nut by hand, then use a socket wrench to alternately and evenly tighten until the top of the torque nut falls off, and then assemble the insulation sheath on the wire clamp fixture.

2. The tightening method of ordinary nuts: Set the torque value of the torque wrench according to the wire section and weather temperature: 20-35NM. Use the torque wrench to alternately and symmetrically tighten the two compression nuts. When the wrench reaches the set torque value, tighten the backup nut to prevent the compression nut from loosening. Then assemble the insulation sheath on the wire clamp.

Non puncture clamping method:

Peel off the insulated wire by about 65-80mm and wrap it with aluminum tape embedded in the wire clamp. Use a wrench to tighten the clamping nut and drive the pressure block seat to clamp the wire. Then assemble the insulation sheath on the wire clamp.
