ABSTRACT:
Electrical insulation for an elongate current carrying body, e.g. an underwater cable for carrying very high voltages, is provided by winding a tape round the body under tension, the tape being made of a film of an axially orientated polymer having a thickness less than 200 microns, and preferably between 10 and 50 microns, a significant degree of crystalline order, a high tensile strength, a high modulus of elasticity, and the ability to cling to itself.
