Abstract (en)
[origin: EP0129755A1] An oil-immersion electrically insulated cable of high performance is constructed by wrapping a conductor with an insulating layer formed by winding on the conductor polypropylene film having a density in the range of 0.905 to 0.915 g/cm<3>, birefringence in the range of 0.020 to 0.035, ratio of strengths in two axial directions (tensile strength in the longitudinal direction/tensile strength in the lateral direction) in the range of 5 to 15, and thickness in the range of 70 to 300 microns, and impregnating the insulating layer with an insulating oil, preferably DDB oil.
