Polyester Film Aluminium Wire
Polyester Film / Non-woven Fabrics Wrapped Aluminum/Copper Wires Strips
Product introduction:
This product is made of oxygen free copper rod or electrical round aluminum rod through a certain specification of the die extrusion or drawing after annealing treatment of the wire, and then on the copper / aluminum wires strips on the 2-3 layer of polyester film or Non-woven Fabrics electrical insulation layer of the winding wire, the product is good, temperature resistance and other grade 130for B grade, mainly used for air core reactor.
Conduct Materials:
Aluminum flat wires strips should follow the standard of GB5584.3-2009, at 20℃ the conductivity resistivity is not more than 0.028mm2/m.
Copper flat wires strips should follow the standard of GB5584.2-2009, at 20℃ the conductivity resistivity is not more than 0.017241mm2/m.
