Stranded Bare Copper Conductors

Stranded Bare Copper Conductors Description

Bare copper cable offers a low impedance and is the essential component of a grounding system. Its applications are wide, it is often used in excavations as an earth electrode, or buried in concrete foundation in civil engineering.
Uni Industry Group Co., Ltd. offers a range of bare copper cables (annealed or not) with cross sections starting from 6 to 300mm². Other sections are also available on request. The composition of the cable strands varies from 7 to 37 strands. The manufacturing process meets the requirements of the IEC EN 60228: class 2 bare copper conductors for grounding installations. 

Find out more about the characteristics of the electrod, lightning protection conductors as per IEC EN 62561-2 standard : Lightning Protection System Components - Part 2: Requirements for Conductors and Earth Electrodes
