Elastomeric cable adapters for power transmission cables and cover assemblies and methods including the same

Abstract

A cable adapter unit for building up an outer diameter of an electrical cable to facilitate fitment of a cold-shrinkable cover sleeve body on the electrical cable includes a cold-shrinkable, tubular, elastomeric cable adapter and a removable holdout. The cable adapter defines a cable adapter through passage configured to receive the electrical cable. The cable adapter includes: an integral, electrically conductive, tubular stress cone layer; and an electrically insulating, tubular outer layer integral with and surrounding the stress cone layer. The stress cone layer and the outer layer each define a portion of the through passage. The holdout is mounted within the through passage and is configured to be withdrawn therefrom. The holdout maintains the cable adapter in an expanded state in which the cable adapter is elastically expanded and, when withdrawn from the through passage, permits the cable adapter to radially contract to a contracted state about the electrical cable.
