Abstract
A cable for power transmission or communication has a core unit having at least one conductor and an insulating layer surrounding each conductor. A first shielding layer surrounds the core unit and is formed of a polymer-carbon composite in which carbon-based particles are dispersed in a matrix of thermosetting polymer material, the first shielding layer having an electrical resistance of 10 Ω·m or less. A metal-based second shielding layer surrounds the first shielding layer.
