Problems solved by technology

However, during use, once the conductor of the power cable is oxidized, the resistance of the cable will increase. On the one hand, the transmission loss will be greatly increased. drop due to volatility
However, due to the physical and chemical properties of the conductor material itself, the current anti-oxidation treatment methods and temperature stabilization methods are difficult to achieve the desired effect. It is urgent to develop an anti-oxidation power cable conductor material to promote the development of power cables.
[0004] In summary, those skilled in the art urgently need to study an anti-oxidation power cable conductor material and its preparation method to solve the problem of performance degradation caused by temperature fluctuations caused by the oxidation of conductor materials during power transmission.

Description

technical field [0001] The invention relates to an anti-oxidation cable conductor material and its preparation method and application, belonging to the technical field of power cable materials. Background technique [0002] In recent years, with the rapid development of high-speed rail and marine projects, the power transmission has increased year by year, resulting in the rapid improvement of power grid technology, the continuous increase of power grid voltage level, and the continuous expansion of power grid construction scale. Therefore, the operation of the power grid More stringent requirements were put forward. The overhead lines used to transmit electric energy in the past are not only susceptible to external interference, which increases the risk of grid transportation costs, but also occupies too much land resources, reducing the utilization rate of land resources, making it difficult to meet the power transmission requirements of the grid. Power cables are widely ...
