Copper Earth TapeBare Copper Earthing Tape

Flat bare copper earthing tapes 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.

HV EHV Earthing Of Substations

Bare copper earth tapes protect 11kV-33kV substations containing high voltage circuit breakers, metering, telemetry and protection equipment.

Earthing tapes for grid and primary substations and switchroom connections (11kV, 33kV, 66kV, 132kV) including both HOT and COLD sites.

A COLD site is a grid, primary or secondary substation where the earth potential rise is less than 430V or 650V (for high reliability protection with a fault clearance time less than 200ms).

A HOT site is a grid, primary or secondary substation where the earth potential rise is greater than 430V or 650V.

Primary Substation – a MV-HV substation with 33kV operating voltage and may include transformers stepping down to 11kV, 6.6kV or 400V.

Secondary Substation – a MV-HV substation with an operating voltage of 11kV or 6.6kV and may include transformation to 400V (Low Voltage).

We have included several downloads opposite covering the Design & Construction guideline specifications which provide useful information from Ofgem and National Grid.

T&D can supply copper earth tapes for earthing, bonding and protection of LV HV substations and networks. The design and effective performance of an earthing solution can have a major impact on potential safety, security of electricity supplies, power quality and construction costs.

BS 7430 Amendment 1:2015

Code Of Practice For Protective Earthing Of Electrical Installations

BS7430 standard covers earthing system design parameters for low voltage and high voltage structures, electrical equipment and systems. BS7430 has significant safety implications as effective earthing safeguards people from the risk of electric shock. To design, specify, inspect and periodically test and maintain earthing systems without endangering those who come into contact with them, users need to follow the guidelines and recommendations outlined in the amended 2015 version of the standard.
