Polymer Insulators and Accessories

For over 50 years, we’ve created products stronger and longer-lasting than porcelain. Our offerings include high-density polyethylene insulators, wildlife protection, and other molded accessories.

HDPE Insulators

Hendrix Polyethylene Insulators are molded from a proprietary blend high density polyethylene. They are ideal for use with all types of construction using either bare wire or covered conductors. We manufacture tie top and vise type pin insulators, as well as tie top, clamp, and trunnion style line post insulators.

Wildlife guard to install on bushings of transformers

Wildlife Protection

Hendrix designed flame retardant raptor guards for use on pin and vise type insulators. Lineduc, perch preventers, and bushing guards are also offered to prevent wildlife interaction with energized conductors.

Stringing tool for use with vise top insulators


Hendrix also offers products for specific applications such as cable restraints, phase spacing, vise top inserts for conductor stringing, and a cable spreading tool.
