● Use
     
FXG8 Series lightning suspension insulators suitable for overhead lines, the overhead insulated wire or bare wire connection Tension rods or rod fittings on the corner, so the tension overhead wires and insulation, and play a role in mine.

●Summary 
    This product is hanging in the transmission and distribution wires on the road, at the right end of the insulator is low, then the left and right ends of the insulator between the high and low voltage electrode to form a space gap, the main channels used to provide lightning flash and arc discharge channel, its action voltage is lower than the insulator body, and the body will inevitably precede insulator flashover before the action, so lightning drainage, protection of insulators and conductors. 
When insulated overhead transmission and distribution grid to DC lightning or induced by lightning, insulators left and right ends of the arc space bar to provide clearance action can be discharged before the insulator flash road, providing lightning flashover channel, lightning flash built up on the network channel frequency of single-phase short-circuit current of the arc or the arc root on the high voltage electrode is fixed to the arc can be supplied, and will not flow onto the string or wire insulator body, thus avoiding the insulator sheds burns, the insulated wire or burnout phenomenon. 
The product line insulators meet the technical standards of the national standard, and will be enhanced insulator various performance indicators, try to plug the discharge, in the case of blockage could not be mine again to ease the way. Insulators and fittings combined anti-arc, can be hung on a tension power transmission and distribution lines, it is relative to the level of tension pole installation can also be hung on a line perpendicular to tighten the bracket, with great economic and practical sex. This product provides several bars arc arc-frequency ablation, reliable performance, can effectively prevent damage due to lightning and insulator insulated conductors lightning break accident occurred. 
Wherein both ends of the mandrel head insulator fittings can be connected to a desired shape according to transmission and distribution lines, and changes its shape to facilitate connection in the line insulators.
