Polyimid-Film insulated Winding Wires
Standard: IEC 60317-43 for round wire

IEC 60317-0-1

IEC 60317-44 for rectangular wire

IEC 60317-0-2

IEC 60172

NF C 31 616  E

IEC 60851 -1-6

Description
Polyimid –film taped ,round or rectangular winding wirs , are copper conductors wich are wrapped tightly with a polyimid-tape, coated on one or both sides with a FEP (teflon )- adhesive e.g.kapton FN , FCR or FWR

The Temperature Index of the insulation is 240

Electrical properties :

4-5 KV  -1 film

8-10 KV -2 film

Conductor material :

Bare copper , soft .

Enamelled copper

Standard range of dimension :

Thickness : 1-6 mm

Width : 2-20 mm

Dimeter (round) : up to 6 mm

Cross section : up to 80 mm²

Advantages : -Very good dielectric strength

-Outstanding resistance to corona discharges

Application: Rotor and stator windings :

Railway traction motors ,

heavy-duty d.c. motors ,

mining machine motors

underwater motors
