Abstract: A device for analyzing or inspecting a prepared portion of a power cable includes a cable gripping section to grip a portion of the power cable proximate to a prepared end of the power cable, where the cable end has been prepared by removing certain portions of the power cable so that it can properly accept an electrical or cable accessory, such as a splice or termination. The device also includes an imaging device holding section to hold an imaging device at a predetermined radial distance from the prepared cable end. In particular, the imaging device holding section is radially and axially adjustable in position. During inspection of the prepared cable end, the imaging device is fully rotated about the prepared cable end to acquire a 360 degree image of the prepared cable end.

Abstract: A support core for an elastic sleeve comprises a first cylindrical section disengagably connected to a second cylindrical section. Each cylindrical section has an annular sidewall made up of a plurality of interlocking concave plates extending longitudinally along a portion of the support core between a abutment end and a distal end. The abutment end of each cylinder section includes a generally helical edge. The plurality of concave plates comprises a top and bottom surfaces, having two opposing longitudinal edges extending between said surfaces on opposite sides of the concave plate. Each of the longitudinal edges comprises an interlocking feature that configure to connect to a mating feature of at least one other concave plate to form one of cylindrical sections of the support core.
