Abstract
A cold shrink product for an electrical system includes a tubular elastomeric layer including an inner surface. The inner surface defines a cavity and first retention features facing the cavity. The first retention features are configured to engage second retention features of a mandrel to resist relative displacement between the elastomeric layer and the mandrel during manufacture of the cold shrink product.

A cold shrink product for an electrical system, the cold shrink product comprising:
- a tubular elastomeric layer including an inner surface, the inner surface defining a cavity and first retention features facing the cavity;
- wherein the first retention features are configured to engage second retention features of a mandrel to resist relative displacement between the elastomeric layer and the mandrel during manufacture of the cold shrink product.
A method for forming a cold shrink product for an electrical system, the cold shrink product including a tubular elastomeric layer including an inner surface defining a cavity and first retention features facing the cavity, the cavity being configured to receive an electrical cable, the method comprising:
- mounting the elastomeric layer on a mandrel such that the first retention features of the elastomeric layer engage second retention features of the mandrel;
- and
- injecting a material along an outer surface of the elastomeric layer to form a second layer on an outer surface of the elastomeric layer, wherein engagements between the first and second retention features resist relative displacement between the elastomeric layer and the mandrel as the material is injected.
A cold shrink product for an electrical system, comprising:
- an inner conductor shield having an inner surface defining a generally cylindrical cavity for receiving an electrical cable, the generally cylindrical cavity having a central axis, the inner surface having a plurality of circumferential projections extending toward the central axis, each of the plurality of circumferential projections being longitudinally spaced along the central axis from an adjacent one the plurality of circumferential projections;
- an outer insulation shield surrounding the inner conductor shield, the outer insulation shield being spaced away from the inner conductor shield;
- and
- insulation material located between the inner conductor and the outer insulation shield.
