Composite electric signal transmitting cable for e.g. tomographic examination, has signal lines and signal line units disposed annularly around outer periphery of coolant pipe comprising tubes such that lines and units are spirally wound

摘要

The cable has tubes (3) that are made of a synthetic resin e.g. urethane resin, and permit the circulation of a coolant e.g. chlorofluorocarbon. The tubes are placed at the level of a central part of the cable. Signal line units (2) are provided, each formed by a bundle arrangement of a set of signal lines (9), where the lines (9) are thermally insulated and comprise an insulated wire. The lines (9) and the units (2) are disposed annularly around an outer periphery of a coolant pipe comprising the tubes such that the lines (9) and the units (2) are spirally wound.
