●  Installation Instructions
The product will be aligned with the wire parallel to the direction of the clip trunking installed on the cross arm, tighten the nut to the feet of steel, equivalent to traditional installation methods insulators; stick toward the load side of the arc.
◆ Piercing clamp method:

1, aluminum nut tightening torque method: the insulated wire clamp parallel card into the slot, first hand tightening torque nut, then wrench tighten alternately and evenly to torque the nut until the top off, then insulated jacket in the clip assembly line fittings on top. 

2, ordinary nut fastening methods: wire section and set according to the weather temperature torque wrench Torque: 20 ~ 35NM, alternating with a torque wrench, tighten the two symmetrical pressure nut torque wrench until the wrench to set the torque value when you can, and then tighten the nut prepared to prevent pressure nut loose, then the insulating sheath assembly line fittings on the folder to.

◆ Non-piercing clamp method:
The insulated wire stripped period of about 65 ~ 80mm wrapped package with embedded aluminum clamp fittings on the compression nut with a wrench to tighten the seat clamp wire to drive compacts, then insulating sheath assembly line fittings on the folder that available.
