Hendrix Molded Products Division began with the development of HPI Tie Top Insulators in the mid 1960’s. The first production units were shipped in 1966, giving Hendrix well over 45 years of field experience. In the mid 1970’s, Hendrix developed and produced the first Vise Top Insulators, where a conductor clamping mechanism was designed into the top of the insulator, and the first production units were shipped in 1976. In 2012 Hendrix introduced it’s Line Post Insulator product line to the market and shipped its first order.
All Hendrix HPI Insulators are manufactured from a proprietary blend of gray, track resistant, high density polyethylene. Tie Top, Vise Top, and Line Post Insulators are tested in conformance with ANSI C29 series of Specifications and exhibit superior electrical and mechanical characteristics as compared to wet process porcelain. They have greater leakage distance, higher flashover and impulse values, are light weight, vandal resistant, won’t chip, crack or break, are a Green recyclable product, and are made in the USA.
