● Installation instructions

Align the wire clamping slot of this product with the parallel direction of the conductor and install it on the cross arm. Tighten the steel foot nut, which is the same as the traditional installation method of insulators; Turn the ignition rod towards the load side.

◆ 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 alternately and evenly tighten it with a socket wrench 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 pressure nuts. When the wrench reaches the set torque value, tighten the backup nut to prevent the pressure 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 fixture. Use a wrench to tighten the clamping nut and drive the pressure block seat to tighten the wire. Then assemble the insulation sheath on the wire clamp fixture.
