ABSTRACT:
An elastically recoverable elastomeric splice cover suitable for use covering a joint connector in a cable conductor having a central body with two distal opposing geometric cones capped by extended endseals, and formed from three contiguous layers,
a) a semiconductive outer shield layer,
b) an inner toroidal electrode disposed along a central axis having a length less than that of the body,
c) and interposed therebetween, an intermediate insulative layer having a length equal to that of the body and geometric cones. The outer shield layer and electrode are formed from a thermally conductive silicone elastomer, and all of the layers are formed from a silicone elastomer having a tear strength of at least about 15 N/mm, and an elongation of at least about 400%. The insulative layer further includes from about 10% to about 35% of an electrically insulative filler, and has a minimum thermal conductivity of at least about 0.18 W/mK, wherein after 30 alternating load current cycles the connector has maintained a temperature of about 10.degree. C. cooler than the cable conductor beyond the splice.
