Polymeric Insulators

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

Using the unique Henley EPDM material, in use for over 25 years, our range of Railway insulators saw first use in 1999. With all the benefits offered by polymeric insulators, the material offers outstanding pollution and weathering performance and is also ideal for tunnels and stations where natural rain washing is not possible.

With a wide selection of substrates and galvanised, malleable iron or Aluminium end fittings available, we believe we have the widest range of Railway insulators available. We are always pleased to customise our range for any local specification.

Our range is Network Rail approved and our manufacturing and quality systems fulfil the requirements of the Link-up scheme for suppliers to the rail industry. Link-up ID: 16788

Product Profiles

This Henley range has been designed for the OLE and Distribution Alliance for West Coast Mainline.

The Design Assurance Group is currently assessing compatability for interfaces and mechanical performance, where the housing and core materials have previously been assessed under RT/E/S/21082.

The OLE & Distribution Alliance DAG have now issued a certificate of recommendation for product acceptance to Network Rail.

W.T. Henley are working closely with Amec Spie on the Manchester South Capacity Improvement Project where these polymeric insulators provide ease of installation and vandal resistance.
