2 Core Screened Cable 1.5 sq mm

Product Description

A shielded cable or screened cable is an electrical cable of one or more insulated conductors enclosed by a common conductive layer The shield may be composed of braided strands of copper or other metal such as aluminium a non braided spiral winding of copper tape or a layer of conducting polymer Usually this shield is covered with a jacket

The shield acts as a Faraday cage to reduce electrical noise from affecting the signals and to reduce electromagnetic radiation that may interfere with other devices see electromagnetic interference The shield minimizes capacitively coupled noise from other electrical sources The shield must be grounded to be effective The shield should be electrically continuous to maximize effectiveness which includes cables splices

In shielded signal cables the shield may act as the return path for the signal or may act as screening only

High voltage power cables with solid insulation are shielded to protect the cable insulation people and equipment
