摘要： A winding wire (1) of a coil for a random-wound stator (20) is provided. The winding wire (1) comprises a conductor (2), an insulation layer (3) surrounding the conductor (2) along a longitudinal direction thereof and a conductive layer (4) surrounding the insulation layer (3) along a longitudinal direction thereof. Whereby the conductive layer (4) has a volume resistivity in the range of 0,1 - 10.000 ohm cm. The corresponding manufacturing method (30) of such a winding wire (1) and a random-wound stator (20) is provided. The random-wound stator (20) comprises a stator body (21) and random wound coils (10) out of such winding wires (1).
