HIGH-SHIELDING LIGHT-WEIGHT CABLES INCLUDING SHIELDING LAYER OF POLYMER-CARBON COMPOSITE

摘要

The present invention relates to a cable for power transmission or communication, the cable comprising: a core portion including one or more conductors, and an insulating layer surrounding each conductor; A first shielding layer surrounding the core portion and formed of a polymer-carbon composite in which carbon-based particles are dispersed in a matrix of a polymer material, and having an electrical resistance of 10 Ω·m or less; And a metal-based second shielding layer surrounding the first shielding layer. With this configuration, a lightweight cable with high shielding efficiency can be provided.
