DESCRIPTION

Product Description: Horizontal Line Post Insulator

The Horizontal Line Post Insulator is a key component in overhead transmission and distribution systems, primarily used for insulating and supporting conductors on crossarms. Installed horizontally, it provides reliable mechanical support while maintaining electrical insulation between the line and grounded structures.

WishPower’s line post insulators feature a composite design with silicone rubber sheds and fiberglass rods, offering excellent resistance to electrical stress, environmental aging, and contamination. Rated for voltages between 10kV and 66kV, they are ideal for use in polluted, coastal, or high-altitude regions.

OEM customization is available for mounting style, dimensions, and voltage class, ensuring compatibility with global project requirements.
