PURPOSE: To enable a cable body and a suspension wire to be easily and properly connected and integrated with each other, ensure low cost for the integration, allow the cable body to be wound around a drum for transport to an installation site, and further enable an installation work to be easily undertaken.
CONSTITUTION: Cable rings 2 made of a plate strip are provided and arranged at the predetermined pitch along the lengthwise direction of a cable body 4. Each cable ring 2 is wound around the body 4 and a suspension wire 6 approximately over the entire surface thereof, with both ends kept at a position faced to the body 4 and the wire 6, thereby constituting a self-support type cable 1 with the cable body 4 and suspension wire 6 integrally jointed.
