Substations and distribution installations require insulation components capable of supporting both electrical and mechanical loads over long operating periods. The 35kV Composite Post Insulator is developed for these applications, providing insulation performance together with structural support for energized equipment.
The insulator combines a fiberglass reinforced core with a silicone rubber housing. This construction reduces overall weight while helping maintain stable performance in outdoor environments exposed to pollution, moisture, and ultraviolet radiation.
Its design makes it suitable for modern distribution infrastructure where installation efficiency and operational reliability are important considerations.
Rated for 35kV applications
Silicone rubber housing
Fiberglass reinforced core rod
Good resistance to environmental contamination
Suitable for outdoor installation
Lightweight compared with traditional porcelain designs
Reliable mechanical support capability
Adapted for utility and industrial projects
This product is commonly selected for:
Electrical substations
Distribution switchyards
Utility infrastructure projects
Pole-mounted equipment installations
Renewable energy connection facilities
Industrial power distribution system
Unlike traditional ceramic constructions, composite post insulators offer a lower overall weight, which can simplify transportation and installation.
The silicone rubber housing provides a hydrophobic surface that helps limit contamination build-up, making the insulator suitable for coastal, industrial, and high-humidity environments.
