Copper strip for cable armouring is widely used in cable manufacturing for armouring, shielding, screening, grounding and protective wrapping applications. It provides excellent electrical conductivity, good corrosion resistance, stable mechanical properties and reliable processing performance during cable production.
Compared with aluminum strip or steel tape, copper strip offers much higher electrical conductivity and better shielding performance. It is suitable for power cables, control cables, instrumentation cables, communication cables, marine cables, mining cables and special industrial cables.
We supply copper strip and copper tape in different grades, tempers, thicknesses and widths according to customer cable design and production requirements.
In cable armouring and shielding applications, copper strip is usually helically wrapped or longitudinally applied around the cable core. It can provide electrical shielding, grounding continuity, electromagnetic interference protection and additional mechanical protection.
The quality of copper strip directly affects cable performance, production stability and service life. Therefore, the strip should have clean surface, accurate thickness, uniform width, stable mechanical properties and smooth edge quality.
Our copper strip for cable armouring is produced with strict control of conductivity, surface quality, dimensional tolerance and edge condition to ensure stable performance in continuous cable production lines.
