Abstract
The termination of a high voltage electric cable includes a rigid heat shrinkable tube that extends between the cable jacket and a connector mounted on the cable conductor. The tube is made from an engineering plastic material and has a Flexural Modulus and a Young's Modulus high enough so as to ensure that the termination is self supporting. The termination may be used in the transmission of power from one carriage to another of an electric train.
Claims11
A self-supporting terminated cable, said cable comprising a conductor, a dielectric and an outer jacket, wherein at an end of said cable to be terminated, said outer jacket of the cable has been removed to expose said delectric, the dielectric has been removed to expose said conductor, and connector means has been secured to the exposed conductor, and wherein an arrangement comprising a first tubular member that is recoverable and electrically insulating and that has a flexural modulus of at least 500 MPa over the temperature range -55.degree. C. to +80.degree. C. is disposed on said cable end such that said tubular member has a wall thickness of at least 1 mm and encloses said exposed cable dielectric and overlaps said cable outer jacket and said connector.
