Needle insulators protect the conductor from burns

The patented puncture structure penetrates the wire insulation layer in the installation line slot to form an electrical connection; The unique arcing fork is bolted to the upper end of the insulator fittings, and the other end is the discharge end, forming a discharge gap with the ground electrode mounted on the lower end of the insulator; There is also an insulating cover to wrap all the exposed fittings at the upper end of the insulator except for the discharge end of the lead fork.

Under normal conditions, the discharge gap of the lightning protection insulator does not move; Only when the lightning overvoltage exceeds the specified lightning can the gap between the arc fork and the ground electrode be broken down, forming a short-circuit channel. The successive power frequency arc burns on the arcing fork of the clip, releasing overvoltage energy to protect the wire from burns.
