HEAT-RESISTANT CABLE Russian patent published in 2003 - IPC

FIELD: cables. SUBSTANCE: heat-resistant cable can be employed to transmit signals from transducers measuring various physical parameters, for instance, temperature and mounted mainly on technological equipment operating under extreme conditions. Invention is aimed at increase of mechanical ( strength and plastic ) properties of cable of same or even smaller diameter and at reduction of number of technological operations in process of cable manufacture. This technical result is achieved by manufacture of sheath of heat-resistant cable from two tubes, as minimum, made of metals ( metal alloys, steels ) which stationary potentials differ by 0.15 V and more and possess opposite signs. Tubes are installed uniaxially with clearance. Clearance is filled with magnesian insulation. Beside this outer and/or inner tubes can be produced from zirconium. EFFECT: increased mechanical properties of cable. 2 cl, 2 dwg
