A new alloy conductor material, which can replace the copper or aluminum material in the current operation of the power grid as a power cable, to reduce the line loss of the power grid, to provide a new superconducting power cable material for the power energy sector.
The invention is realized as follows: superconducting power cable, using barium - copper - oxygen system to add niobium and titanium alloy conductor, the processing process is as follows: production of alloy wire - stranding - forming - plating insulation film - vacuuming - cable formation - three times coating - jacket - microcomputer detection - printing factory label - rewound disk - head - packaging - inspection - qualified report - leaving the factory; The cable adopts the alloy conductor of barium - copper - oxygen system plus niobium and titanium. The powder of the alloy conductor is pressed into the silver tube by cold isobaric method and processed into wire by extruding and drawing method. The 55 pieces are bunched together and then stretched and rolled into a belt with a thickness of 0.25mm and a width of 3.5mm. The drawing and discharging process adopts the process of crossing the end of the drawing line.
The advantages and effects are:
1. The superconducting cable can be processed for hundreds of miles by the process of crossing the wire.
2. Alloy conductor, rich material resources, and the original ordinary cable material price reduced by half the price, reduce the factory processing costs.
3. The guide cable system can withstand short circuit current in a short time.
4. The overload period of the force system is long, and the cut-off amount of the cable has nothing to do with the laying conditions such as soil.
5. The price of superconducting cable and ordinary cable competition, because of the superconducting cable beyond, will soon be recognized by people, soon into the commercialization of cable industrial products will cause a very serious impact, especially the large capacity of the cable is 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 cable is 5-7 times that of conventional cable.
8. Superconducting cables use fewer metals and insulation materials than conventional cables and do not pollute the environment.
