CONTINUOUSLY TRANSPOSED PAPER INSULATED COPPER WIRE HIGH FREQUENCY
COPPER LITZ WIRE The manufacture process is as follows: Strips of mutual insulated
round copper wire transpose, strand, roll into rectangular section
wire in the same direction at certain pitch, then insulating film
and insulating composite materials is wrapped from inside to
outside. Here are three types: Paper insulated polyvinyl-acetal enameled Continuously Transposed
copper wire Paperless Insulated Netting-type Continuously Transposed copper
wire Heat Resistant Continuously Transposed enameled copper wire
FEATURES Reduce additional circulation current loss Eddy-current loss caused by leaking magnet field Improve the mechanical strength of coil
