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
zinc coating comply to IEC and ANSI such international standards .
the insulator is with tie top , neck demension 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
silicone rubber , high mechanical strength, high corona resistance
permeability to moisture.
Interface between silicone rubber and fiberglass rod are well
This feature prevents intrusion of moisture and contaminating
The 46 kV silicone rubber post insulators are used on distrbution
lines . These insulators are commonly installed vertically on metal
or wooden structures based to support the
. The finish product have excellent mechanical and electrical
• Eliminate or Reduce Maintenance and is compatible with existing
• Improves Power Quality (lower RI and TVI)
• Safety (light weight for handling and installation)
• Service Life (consistent performance over its service life)
