MILFORD, NH (April 28, 2015) – Marmon Utility LLC/Hendrix Molded Products, a premier provider of quality products and services for the electric utility industry, has long been manufacturing high-density polyethylene insulators and accessories as an alternative to porcelain.

Hendrix has been a leader in molded polymer products since the introduction of the HPI Tie-Top insulator in the mid1960s, with continued product innovation throughout the years, including the industry’s first Vise-Top insulator, introduced in the ’70s. Hendrix Molded Products are made of high-density, recyclable polyethylene, and are 100 percent made in the USA. The company’s products include Tie-Top, Vise-Top, and Universal Vise-Top pin insulators.

The benefits to polyethylene insulators for the utility market as compared to their porcelain counterparts are many and include greater leakage distance, higher flashover and impulse values, lighter weight, and vandal-resistance. In addition, Hendrix polyethylene molded products won’t chip, crack, or break; they accept any conductor or tie (bare or covered); and they’re completely interchangeable with porcelain – so upgrading is easy. The Hendrix insulators also exceed the electrical and mechanical requirements of ANSI, and there are millions of HPI insulators in service around the globe.

“At Hendrix, we’ve long known the benefits of polyethylene insulators, since we launched them 50 years ago…We’ve found that once customers try our molded products, they see the benefits for themselves and make the switch to take advantage of the improvements. It’s a great product that really makes sense.”

Ken Woo, Director of Sales for Hendrix Molded Products
