Product Instruction : Paper covered wire , Composite wires
Paper covered winding wire is made up of bare or enameled conductor from oxygen free copper rod or electrical aluminum rod by drawing or extruding processing and wrapped by insulation materials.
Composite wire (Multiple Strips paper covered wires) is made up of several strips of bare copper/aluminum wire, or paper covered single wire ,or enamel flat wire, or their composite with insulation wrapping in the outside layer 
Product Usage: Power Transformer,Traction Motor & Transformer,and Reactor’s winding

Enamel thickness   usually 0.10~0.16 mm for Acetal, usually 0.03-0.05mm for Epoxy which is chosen  as per different thermal class, and Side B can be Epoxy-coated on one side or two side.
Max wrapping layers once    24 layers for paper covered wire
                                                 4 layers per wire and 16 layers outside for composite wires
We could offer products of special requirements on conductor size, insulation layer thickness, or wire number of the composite.
