  • Publication number: 20220164940
    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.
