Power cables for power sources, especially superconducting power cables. Using barium - copper - oxygen system plus niobium and titanium alloy conductor, the processing process steps are: production of alloy wire - stranding - forming - plating insulation film - vacuum - cable - three times coating - jacket - microcomputer detection - printing label - rewound disc - head - packaging - inspection - qualification report - factory. The take-away and pay-off process adopts the over-end take-away process. The aluminum cladding of superconducting power cable is made of corrugated pipe made of titanium alloy material. Superconducting cables can be processed for hundreds of miles, the power system allows a long period of overload, and the amount of cable interception is independent of laying conditions such as soil. The superconducting cable is made of liquid nitrogen gasification alloy material without resistance, and the electric loss is 0. Superconducting cable's current transfer capacity is 5-7 times that of conventional cable.
Superconducting power cable, the use of barium - copper - oxygen system to add niobium and titanium alloy conductor, its processing steps are: production of alloy wire - stranding - forming - plating insulation film - vacuum - cable - three times coating - jacket - microcomputer detection - printing label - rewound disc - head - packaging - inspection - qualification report - factory; The cable adopts barium-Cu-oxygen system plus niobium and titanium alloy conductor is their powder, pressed into the silver tube by cold isobaric method, processed into wire by extrusion drawing method, the 55 bundles together and then stretched, rolled into a thickness of 0.25mm, a width of 3.5mm, after intermediate annealing and periodic thermal mechanical processing, and then the use of microcomputer controlled wiring machine, made of cable conductor. The take-away and pay-off process adopts the over-end take-away process.
The advantages and effects of the invention are:
1. Due to the use of the over-end line process, the superconducting cable processing length can reach hundreds of miles.
2. The use of alloy conductors, rich material resources, and the price of the original ordinary cable material is reduced by half the price, reducing the factory processing costs.
3. The guide cable system can withstand the user's short circuit current in a short time.
4. The overload cycle of the force system is long, and the amount of cable interception has nothing to do with the laying conditions such as soil.
5, the price of superconducting cable and ordinary cable to form competition, because of the superconducting cable beyond, will soon be recognized by people, soon into the commercialization, will have a very serious impact on the cable industry products, especially large-capacity cables more obvious.
6. The guide cable is made of liquid nitrogen gasification alloy material without resistance, and the electric loss is 0.
7. The current transmission capacity of superconducting cables is 5-7 times that of conventional cables.
8. Superconducting cables use less metal and insulation materials than conventional cables, and there is no environmental pollution.
