Abstract

A multicore electrical cable (38) includes a plurality of insulated electrical conductors (46), each including at least one conductor wire strand (28,28a) forming the conductor core (42). A plurality of conductor wire strands (28,28a) are helically twisted together to form the conductor core (42) and the interstices between strands are filled with a conductive sealant (40) or one conductor wire strand forms the conductor core. The conductor cores (42) are over sheathed by a polymeric insulation layer (30), with a layer of an adhesive (44) provided between the polymeric insulation layer (30) and the conductor core (42) to fill interstices therebetween. The insulated electrical conductors (46) are bundled together, and over sheathed by an outer polymeric insulation layer (50), with a layer of adhesive filler (48) provided between the outer polymeric insulation layer (50) and the insulated electrical conductors (46). A subsea umbilical is also provided.
