A high voltage interconnection system for electrically interconnecting a pair of objects that are movable relative to each other includes a flexible cable, a connection arrangement electrically contacting an end of the flexible cable, and a cable holder arrangement holding the flexible cable in a slidable manner. The cable holder arrangement may include a wear plate fixed to at least one of the objects and a sliding collar fixed on the flexible cable. The collar may be slidably supported to protect the flexible cable from damage as it moves.
