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.
