Line Post Insulators

Line Post Insulators are molded from a proprietary blend of gray, track and UV resistant high density polyethylene. They are a lightweight alternative to traditional porcelain post insulators and are ideally suited for all types of structures using bare or clad conductors.

When using covered conductors, it is always recommended to use HPI insulators to match the dielectric properties and reduce electrical stress at the interface.

Application

Line post insulators are used in high-voltage electrical power transmission systems to isolate energized conductors from grounded structures. They provide electrical insulation and mechanical support for overhead power lines, protecting them from damage due to accidental ground contact and reducing the risk of electrical outages. They are commonly made of porcelain, glass or composite materials and are designed to withstand extreme weather conditions, high mechanical loads and long-term exposure to electrical stress.
