Insulator 51-4F

IEC standard 46KV vertical composite line post insulator , grey color for distribution lines. 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 . The insulator is with tie top , neck dimension is 51-4F . They are crimped directly to the rod by a special process originated ,The crimp requires no intermovement of the parts to achieve high strength, nor does it introduce potting compounds or adhesives. 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. Applications: The 46 kV silicone rubber post insulators are used on distribution lines . These insulators are commonly installed vertically on metal or wooden structures based to support the conductor . Competitive Advantage: . The finish product have excellent mechanical and electrical performance. • Eliminate or Reduce Maintenance and is compatible with existing plant • Improves Power Quality (lower RI and TVI) • Safety (light weight for handling and installation) • Service Life (consistent performance over its service life)
