ABSTRACT:
A composite cable with built-in signal an power cables is mainly used as a control cable for a machine tool and the like. The composite cable contributes to reduced cost, downsizing, higher reliability and higher safety, which are obtained because only a single cable needs to be laid, instead of the conventional cable, which requires multiple cables to be laid. In the composite cable with the built-in signal and power cables, a flat signal cable formed by a plurality of insulating cores arranged in parallel in the lengthwise direction, and having alternately repeated combined portions and separate portions is spirally wound into a roll around one or more power cables provided in the center of the composite cable. The power cables each have a large conductor size. A first shield is optionally provided around the flat signal cable. A second shield is optionally provided around the power cables. A sheath is provided around the flat signal cable or the first shield.
