Molded Header


Hendrix Line Post Insulators are molded from a proprietary blend of gray, track and UV resistant, high density polyethylene. They are the lightweight alternative to traditional porcelain post insulators and are ideal for use with all types of construction using either bare or covered conductors.

When using covered conductors, it is recommended that HPI insulators always be used in order to match dielectric properties and reduce electrical stress at the interface.

HPI Line Post Insulators meet the electrical and mechanical requirements of ANSI C29.18. They are designed with standard tie-top head dimensions and a center tap ¾” base thread for stud bolt mounting.
