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 aluminum or ductile iron.
In case the material is ductile , the fittings surface are hot dip
galvanized .
zinc thickness comply with IEC and ANSI such international standard
requirement .
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 - Weathersheds are high pressure injection molded .
Housings manufactured with
silicone rubber exhibit hydrophobicity, 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 35 kV silicone rubber post insulators are used on distrbution
lines or substations. These insulators are commonly installed
vertically on metal or wooden structures based to support the
conductor or power apparatus.
Competitive Advantage:
. Improved Reliability
• 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)
