    Abstract: A cable including a conductor surrounded by a covering layer, the covering layer formed from a thermoplastic vulcanizate composition which includes a continuous phase and a dispersed phase. The continuous phase is formed of a thermoplastic polyolefin. The dispersed phase is formed of a cross-linked elastomeric polyolefin. The thermoplastic vulcanizate composition passes the Hot Creep Test at 150° C. in accordance with UL 2556 (2013) and has a dielectric loss of 3 or less. Methods of forming cables with coverings are also disclosed.

    Abstract: The invention relates to semiconducting shield compositions for electric power cables having a base polymer system, nano-talc, and carbon black. The invention also relates to such semiconducting shield compositions and the use of these semiconducting shield compositions to manufacture semiconductive shields for use in electric cables, electric cables made from these compositions and methods of making electric cables from these semiconducting shield compositions. The semiconducting shield compositions of the invention may be used as strippable “semiconducting” dielectric shields (also referred to as the core shields, dielectric screen and core screen materials) in power cables with cross linked polymeric insulation, primarily with medium voltage cables having a voltage from about 5 kV up to about 100 kV, preferably up to about 35 kV.
