ABSTRACT:
A cable (100, 120) for transmitting electrical energy is constructed with a layer (104) of insulating and shielding material made up of pre-impregnated strands, for example glass strands (105), carrying a nonlinear dielectric material concentrically formed about an electrical conductor (102). A portion of the layer (104) is displaced by stranded material (116) pre-impregnated with a thermally conducting material to define a longitudinal heat distributing channel (114) along the cable (100, 120). The layer (104) of nonlinear dielectric material improves field control within the cable (100, 120) and also the temperature profile along the cable (100, 120), both of which improve performance and life expectancy. In addition, the electric field and the electromagnetic interference (EMI) around the cable (100, 120) are reduced. The longitudinal heat distributing channel (114) further improves the temperature profile along the cable (100, 120).
