Pure Copper Flat Bus Bar Copper Tape For Lightning Grounding Protection System
Our Lightning Grounding Protection System is built around high-conductivity 99.97% pure copper flat bus bars and copper tapes, designed for reliable earthing and equipotential bonding. Manufactured in China under strict ISO 9001:2015 standards, these copper conductors offer tensile strength up to 1040 MPa and a service life exceeding 50 years. Whether you need T2 or T3 pure copper, custom thicknesses (3–6 mm), or custom widths (20–40 mm), we provide flexible, corrosion-resistant solutions for electrical grounding and lightning protection.
With excellent conductivity (15%–99.99% IACS depending on application) and strong anti-corrosion properties, our copper earth bars and tapes ensure near-zero equipotential voltage, protecting both people and sensitive equipment from fault currents and lightning strikes. Easy to install and available with custom lengths and logos.

A: Our standard earthing tape is 99.97% pure copper, with T2/T3 pure copper options available. Higher purity (99.99%) can be provided upon request.
A: Yes. Standard widths: 20/25/30/35/40 mm. Standard thickness: 3/4/5/6 mm. Any custom dimension is available – just contact us.
A: T2 offers slightly higher conductivity and purity (≈99.95%), while T3 is also pure copper (≈99.90%) and more cost-effective. Both work excellently for grounding and lightning protection.
A: Over 50 years in normal atmospheric and soil conditions, thanks to copper’s natural anti-corrosion properties.
A: Yes. It meets ASTM, GB, and ISO 9001 standards, and we can provide certification upon request.
A: From 560 MPa to 1040 MPa, depending on the temper and processing.
A: Yes, samples are available with a lead time. Please contact our sales team.
A: It can be cut, bent, and drilled easily. Commonly installed using exothermic welding, mechanical clamps, or bolted connections.
