A cable is used for running a load between surface and downhole in a well. The cable includes one or more wires composed of a non-metallic material. Each of the one or more wires bears the load from the surface and can electrically conduct between the surface and downhole. An insulating material is disposed about the one or more wires and insulates the electrical conduction. The non-metallic material includes a carbon nanotube wire. A jacket can be disposed about the insulating material, and the jacket can be composed a non-metallic material also, such as carbon nanotube wire. Markers disposed at predefined distances along the length of the cable are used to determine the deployed length of the cable.
