    ●Composition

    It consists of a copper tape coated on single side or double 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.

    ●Standard

    YD/T 723.4-2007.

    ●Packing

    In roll, then pack into wooden case, the core material is paper/steel/plastic
