End fittings are aluminum or ductile iron.
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)
