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
