Polyester Film Covered Aluminum magnet wire
Polyester Film / Non-woven Fabrics Wrapped Aluminum/Aluminum magnet wire Strips
Product introduction :
This product is made of oxygen free Aluminum 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 Aluminum / Aluminum magnet wire 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 magnet wire strips should follow the standard of GB5584.3-2009, at 20℃ the conductivity resistivity is not more than 0.028mm2/m.
Product breakdown voltage should follow below table:
