The product is formed by winding nomex paper, cable paper and polyimide film on the high-quality copper (aluminum) conductor, so that the film and the conductor are bound as a whole. The product has good voltage resistance and small insulation thickness, and the heat resistance is up to 220℃. It is mainly used for winding of the motor, reactor, electric welding machine or other similar electrical products.
Conductor material:
The aluminum flat wire shall conform to provisions in GB5584.3-2009, and resistivity at 20℃ shall not be larger than 0.0280Ωmm2/m.
The aluminum flat wire shall conform to provisions in GB5584.2-2009, and resistivity at 20℃ shall not be larger than 0.017241Ωmm2/m.
After wide edge bending and narrow edge bending of the paper-wrapped line on the round bar specified in the following table, the wrapping layer shall be free of cracked or naked conductor:
