● Use 
     Overhead insulated wire to prevent disconnection of lightning protection devices for copper, aluminum insulated overhead conductors.
●Performance parameters
1, full-wave lightning impulse withstand voltage (peak) kV: 100 
2,1 min power frequency withstand voltage (rms) kV: 50 
3, frequency arc current (rms) kA: 12.5 
4, the puncture site is coated with a special waterproof insulating paste

●Installation instructions
The product is installed in the load side of the line insulator.
◆ Piercing clamp method:

1, aluminum nut tightening torque method: the insulated wire clamp parallel card into the slot, first hand tightening torque nut, and then alternating evenly socket wrench to tighten the nut torque until the top off, then insulating sheath assembly in the clamp fittings can be. 

2, ordinary nut fastening method: set according to wire section and weather temperature torque wrench torque values ​​:20-35NM, alternating with a torque wrench, tighten the two symmetrical compression nut until the torque wrench torque wrench to set the value of 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.
