Index > Product > Copolymer Coated > Copolymer Coated Aluminum Tape
Copolymer coated copper tape applies for medium and high voltage power cables as a shield/moisture barrier as a moisture/ chemical barrier for cable core, it consists of a copper tape coated on single side with a special ethylene copolymer color-coded green. The coating forms a strong moisture-resistant bond to the copper substrate that will not delaminate from contact with the copper. The coatings also form strong polymeric bonds to zero halogen, polyethylene and chlorinated polyethylene jacketing resins during the jacket extrusion process thereby allowing fabrication of “bonded jacket” or laminate sheath, cables. The copper alloy is fully annealed which has high conductivity and easy fabrication characteristics.
