69kv/115kv/138kv composite post insulator Silicone Rubber Line Post Insulators IEC standard composite line post insulator grey color for distribution lines and railway system

OEM production is accepted



Insulator fiberglass rod is produced from the highest quality materials. Strands are aligned for maximum tensile strength. The rod is more than 50 percent glass fibers in cross section.

End fittings are cast steel . The fittings surface are hot dip galvanized .

Zinc coating comply to IEC and ANSI such international standards .

Weathersheds are high pressure injection molded . Housings manufactured with silicone rubber , high mechanical strength, high corona resistance and low permeability to moisture.
Interface between silicone rubber and fiberglass rod are well treated.

This feature prevents intrusion of moisture and contaminating elements.
