Copper Earth Bars for Lightning Protection Systems

Earth bars are an integral part of an Electrical oBuilding Services or Substation technical specification for earthing and bonding; they provide a convenient common earth point for the infrastructure. It is critical copper earth bars provide long lasting, high quality earthing capable of enduring any potential dangerous fault currents.

Main earthing bars provide a recognised earth connection/ reference point and allow the local substation earth resistance to be measured using a clamp meter.

Thorne & Derrick and AN Wallis are aware of the crucial role of an Earth Bar which is why they manufacture high quality, affordable earth bars that are designed and tested to all relevant standards – manufactured from hard drawn copper bar to BS EN 13601 and tested to BS EN 62561-1 Class H.

Earthing bars can be tinned and bases powder coated to improve corrosion resistance
Bars are pre-drilled with cable connection holes with optional threads for installation ease
Manufactured from highest conductivity and quality copper to British Standards
Full range of standard, single and twin link types for LV, MV & HV switchroom/substations
Customised to suit the earthing requirements of your project on short lead times
