FFLW-12 series high-voltage needle type composite puncture type (non puncture type) anti arc insulatorDetailed product description：

FFLW-12/5T20 puncture type (non puncture type) anti arc insulator is a new type of composite structure product. Insulated conductors are widely used in distribution lines both domestically and internationally, but their inherent lack of lightning resistance makes them prone to wire breakage accidents when struck by lightning. This product is a new type of combined structure two in one puncture type anti arc insulator. Its composite insulator has good insulation performance and anti pollution level, and can be used for insulation and supporting wires in 10KV overhead power lines. It also has the protection function of preventing 10KV overhead insulated wires from lightning strikes and wire breakage. This product also has a moving pressure block and a puncture type tooth structure to prevent the wire from moving due to thermal expansion and contraction. The installation and construction are convenient and reliable, and there is no need to peel off the insulation layer, which can avoid water ingress and corrosion of the wire core.
