Hendrix is a manufacturer of aerial spacer cable systems, molded polymer
insulators and vise top insulators and TR-XLPE insulated,
medium voltage power cable rated 15kV to 35kV.
Bill Hendrix founded Hendrix Wire & Cable, Inc. in 1951. His mission was to manufacture and market an overhead
electrical distribution system (Aerial Spacer Cable) he invented. The first products produced by Hendrix were
patented overhead spacers and polymer insulators. The system solved the reliability problems that local utilities
were experiencing. The Aerial Spacer Cable greatly reduced power outages caused by various elements in the environment.
Other benefits that soon became apparent included less frequent tree trimming, reduced right of way concerns, ease of
operation in contaminated environments, and the ability to span cable over a long distance. These factors contributed
to overall lower operating costs for the utility.
Hendrix Molded Products Division began with the development of HPI Tie Top
insulators in the mid 1960’s giving Hendrix almost 50 years of field experience making polymer insulators. In the mid 1970’s, Hendrix
developed and produced the first Vise Top Insulators, where a conductor clamping mechanism was built into the top of the insulator.
In 2012 Hendrix introduced its Line Post Insulator product line to the market.
In 1967 Hendrix expanded his product line by entering the underground cable market. Hendrix has been a leader in promoting
electrical test requirements in the cable industry and in other quality advancements such as clean room technology to
eliminate contamination in cable insulation. Hendrix has built a reputation for high quality cable, short, consistent
lead-times and responsive customer service.
Our products are operating world-wide. They have endured extreme environment
condition, from the tropical rain forests of Brazil to the snow covered mountains of Antarctica. Hendrix is ISO 9001
certified and continues to make quality, service and reliability the centerpiece of the Hendrix philosophy.
Hendrix is located in a 250,000 square foot facility in Milford, New Hampshire.
Hendrix fabricates bare aluminum and copper conductors for the manufacture of utility power cables.
True-triple, gas-cure primary extrusion lines are fully supported by neutral and jacketing machines.
Electrical and physical test facilities are capable of performing all standard industry tests and Hendrix’
own internal quality tests. An analysis lab handles qualification testing, compound development and failure
analysis for customers. At Hendrix’ recently opened Molded Products production facility in nearby Amherst,
New Hampshire injection molding presses produce high quality Molded polymer insulators,
both tie top and vise top plus aerial spacer cable components.
