Abstract:
1. A torsion resistant shielded cable for a wind turbine, comprising: at least one conductor; an insulating layer, covering the conductor; a first isolating layer, surrounding the insulating layer; a shielded layer, including a plurality of shield wires; and a second isolating layer wrapping the shielded layer; wherein the second isolating layer is made of alloy to provide shielding against electromagnetic interference (EMI) emitted from the torsion resistant shielded cable; and wherein the shield wires are wound around the first isolating layer clockwise and counter-clockwise interleavedly along an axial direction of the conductor to prevent the shield wires from breaking while the torsion resistant shielded cable is twisted back and forth constantly during rotation of the wind turbine.
