Abstract

In order to improve a multi-conductor control cable comprising conductor bundles utilized in container loading devices (spreader cables) so that it can transmit video signals, a stranded unit is provided in place of a conductor bundle. This stranded unit consists of only four stranded elements: an optical waveguide cable; a stranded element with a diameter equal to the diameter of the optical waveguide cable; and two additional stranded elements of smaller diameter.
