Insulated electrical conductor
Abstract
Abstract THE INSULATED CONDUCTOR OF THE INVENTION COMPRISES AN ELECTRICALLY CONDUCTIVE METAL CORE HAVING A POLYOLEFIN INSULATING COVER THEREON AND A ELASTOMER SHEATH OVER THE INSUALTING COVER. THE ELASTOMER SHEATH IS BONDED TO THE POLYOLEFIN COVER BY A SUITABLE THERMALLY APPLIED ADHESIVE COMPOSITION. THE METHOD OF THE INVENTION COMPRISES THE STEPS OF PROVIDING AN ELECTRICALLY CONDUCTIVE METAL CORE, COVERING THE CORE WITH A POLYOLEFIN INSULATING LAYER, HEATING THE INSULATING LAYER TO A TEMPERATURE OF 400 TO 500*F., THEN APPLYING A SUITABLE ADHESIVE COMPOSITION TO THE INSULATING LAYER WHILE IT IS IN THE TEMPERATURE RANGE OF 400 TO 500*F., THEN APPLYING A SECOND APPLICATION OF THE ADHESIVE COMPOSITION TO THE POLYOLEFIN-ADHESIVE COVERED CONDUCTOR, AND THEN APPLYING AN ELASTOMER SHEATH TO THE POLYOLEFIN-ADHESIVE COVERED CONDUCTOR AFTER THE SECOND APPLICATION OF ADHESIVE COMPOSITION HAS BEEN APPLIED THERETO.
