Hard Drawn Copper Earth Bars

Hard Drawn Copper Earth Bars

Thorne & Derrick distribute the complete range of Earth Tapes manufactured from high conductivity hard drawn copper by AN Wallis in an extensive range of widths and thicknesses from 20 x 3mm (60sqmm C.S.A. Cross Section Area) to 100 x 6mm (600sqmm C.S.A.) – hard drawn copper earthing bars are available in 4m lengths.

The A N Wallis hard drawn copper bar has a high conductivity for use in high voltage distribution and control applications including switchgear, transformers, control panels and panel boards – the copper bars are also available in tinned versions.

Hard drawn copper earth bar conductors with fault current ratings according to BS7430 with an initial copper conductor temperature of 30°C and a maximum temperature of 250°C.

Copper Earth Bars

Hard drawn copper earthing bars are specified for above ground earthing conductors due to copper theft risk of insecure stranded copper conductors – a complete range of earth bars, connector joints, fixing clips and clamps for connecting conductor tape to copper earth rods.

cOPPER Earth Tapes

Earth Tapes, Cables & Conductors – bare copper, PVC covered and LSOH (Low Smoke Zero Halogen) tapes, hard drawn copper bar and earth braids. LV-HV-EHV earthing tapes and systems for substations, transformers and generators.

Substations LV MV HV

Thorne & Derrick supply DNO’s, IDNO’s, ICP’s and utility power contractors involved in the construction and maintenance of MV-HV substations – this includes duct seals for underground cable duct, cable cleats to support cables, underground cable protection and a full range of MV-HV cable joints, terminations and connectors in heat shrink, cold shrink and push-on technologies for XLPE, PILC, oil and gas insulated cables.
