Copper Earth Bars

As the UK’s largest distributor of copper earth bars we can provide excellent service for the complete range of Earthing & Lightning Protection products including copper tape, rods, clamps and ancillary items.

  • Earthing bars can be tinned and bases power 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

Substation earthing bars (LV HV) are used to marshall earth connections, connect copper earth rods or earth cable conductors using crimp lugs for terminations in substations, cable pits, feeder pillars and switchgear.

Earth Bars

Earth Bars & Marshalling Bars

All earth connections are usually labelled and connected via separate connections to a dedicated copper earth bar (GRP/brick-built designs) or marshalling bar (integral/basement designs) which in turn shall be connected to the main transformer/switchgear earth terminal to allow:

  • Personnel to determine if the earthing is intact when entering the substation
  • The earthing to be easily identified
  • The earth resistance to be measured using a clamp meter

Note: At new enclosed high voltage substations the HV earth bar within the LV feeder pillar shall not be used to marshal the earthing connections as access, particularly at IDNO substations, to the LV cabinet/pillar is not always available. However it is acceptable to use the HV earth bar within the LV feeder pillar at existing outdoor sites for all earth connections to prevent theft.
