The OPGW/OPPC structure contains optical units and metal wires, which need to be wound on a tool tray suitable for the cable laying machine’s winding cage during cable laying. In order to reduce material loss, these wires are often in large trays (or bundles) when entering the factory, often poorly arranged and under uneven stress, and may also have joints. Therefore, it is necessary to use a wire rewinding machine to match these wires. The auxiliary equipment of OPGW/OPPC mainly includes rewinding machines for wire, steel pipes, and finished cables.
