Polymeric electrical insulator
W.T. Henley

W T Henley was quick to identify the benefits of using composite polymer insulator technology to replace traditional materials such as glass or porcelain for Insulators.

We developed a unique EPDM* cladding material formulation, which has been in service now for more than a quarter of a century and in a variety of applications.

*Most products are now also available in Silicone

Benefits include
Light weight
Impact and vandal resistant
High pollution resistance
Low profile - makes them less environmentally obtrusive
Flameproof
A wide range of substrates and end fittings
Many direct replacement products to obviate the need to re-tension lines after replacement of traditional insulators

The range consists of
Distribution Insulators
Stand-Off Insulators
Insulators for OEMs
Railway and Light Rail Insulators
