Abstract
Abstract A CABLE HAVING AN IMPROVED CORE SCREEN OF CONDUCTIVE POLYMER MATERIAL ON THE CORE OF THE CABLE IS PRODUCED BY PASSING A CABLE HAVING A LAYER OF INSULATION AS THE CORE THROUGH A BATH CONTAINING A LATEX OF CONDUCTIVE POLYMER MATERIAL SUCH AS A BLEND OF A COPOLYMER OF ETHYLENE AND ACRYLIC ACID AND CARBON BLACK TO DEPOSIT THE BLEND ON THE CABLE CORE. A STRIP OF METAL IS THEN WRAPPED OR OTHERWISE FORMED AROUND THE CORE SCREEN TO PROVIDE A PROTECTIVE METAL SHIELD. AN OUTER JACKET OF PLASTIC CAN THEN BE EXTRUDED OVER THE PROTECTIVE METAL SHIELD.
