Earthing Straps

Our highly flexible earthing straps and earth leads are made from high conductivity copper grade Cu-ETP and are used in electrical distribution, building services and process plants for a wide range of applications including lightning protection.

By selecting the correct braid, termination and insulation, our earthing straps are optimised for each application and required performance criteria with respect to temperature, flexibility, corrosion resistance, weight and electrical characteristics. ( Current ratings.) Call our sales office for assistance in specifying the appropriate product for your application

We have a different web page for our range of Earth Bonds made from round braid and a separate web page for earthing straps made from Stainless Steel.

Our Earthing Straps can be supplied with or without insulation with competitive pricing and ex stock / short lead times. Contact our sales office for further information or complete our enquiry form if what you need is not in our shop.

Why use copper braid for earthing?

Copper braid provides a flexible, low-resistance path to ground. It handles vibration and movement better than rigid bars, ensuring reliable earthing in substations and cabinets.

Can copper braid be used for lightning protection?

Yes. Copper braid safely connects lightning protection systems to earth grids, allowing high current surges to flow without damage.
