Product Image

VDWWD_OpenGraph

Hendrix Polyethylene Insulators (HPI) are molded from a proprietary blend of gray, track resistant, high density polyethylene. They are ideal for use with all types of construction using either bare wire or covered conductors.

When using covered conductors, it is recommended that HPI Insulators always be used in order to match the dielectric properties of the insulating materials.

Hendrix Tie Top Insulators are designed with standard ANSI neck and thread sized and are available for systems with nominal voltage ratings of 15KV, 25KV, and 35KV. They conform with the electrical and mechanical requirements of ANSI C29.5 and C29.6.
