China's smart grid construction has proposed the concept of accelerating the development of the superconducting industry. Specific to the cable industry, the process of industrialization of superconducting cables may be accelerated, but at present there are still no conditions for large-scale industrialization.
If the price of the superconducting cable is attractive enough, the commercial application prospect of entering the smart grid should be very broad. However, in the near future, due to limitations in superconducting basic research, technical personnel, superconducting materials, and cable process equipment, as well as the concept of pricing policies, the prices of superconducting cables will definitely be higher than existing ordinary cables. Far more, therefore, people are not optimistic about the market prospect of superconducting cables.
According to calculations, the current capacity of high-temperature superconducting wires is more than 100 times greater than that of the same cross-section copper wire. If superconducting cables are used to replace copper and aluminum transmission lines in certain aspects, a large amount of copper materials will be saved. From the point of view of saving copper materials, the economic benefits of using the superconducting cable to save copper are compared with the price of superconducting cables. In the end, the overall economic benefit is not yet reported.
The superconducting products for smart grids are not just superconducting cables, but also superconducting generators, superconducting transformers, superconducting current limiters, and superconducting energy storage devices. The development of various products is mutually restrictive. We can't hopefully exaggerate the development of the superconducting cable industry, but we should look to see if the development of other industries is suitable. The cable is only an accessory product of electromechanical equipment. Technological advances in electromechanical equipment have led to improvements and improvements in cable structure and performance. The interaction between the motor and the enameled wire is a good example.
It is said that the State Grid is planning to build a 1 kilometer long and 110 kV high temperature superconducting cable demonstration project, which is planned to be completed in 2012. Moreover, the National Grid and China Southern Power Grid's construction and investment in superconducting pilot demonstration projects will greatly stimulate the development of the domestic superconducting equipment industry, and the huge investment prospects of the superconducting industry will thus emerge.
However, the head of the Institute of Superconducting Power of the Chinese Academy of Electric Power came to Xiaokang recently and said that superconductors now do not have the conditions for large-scale industrialization, but they also need to stimulate the development of related equipment by expanding demonstrations to promote the development of the superconducting industry. It can be seen that overemphasizing the market prospects of superconducting cables can only be used to fill the hunger and hope to quench the thirst.
As for the advantages of superconducting materials, just like nanomaterials, it is recognized worldwide as a popular science knowledge, and it does not need to be more expensive and tongue-in-cheek to publicize, let alone to mislead cable companies, cable markets and social investors. The cable industry has been calling for nanomaterial technology for many years. Perhaps the promotion is not large enough, and there has not been a large number of applications.
After the heat of nuclear power, wind power, submarine and EHV cables, it is not known whether superconducting cable heat will rise again. It is not a bad idea to hold some seminars on superconducting cables in a small area. It is no longer necessary to inflate the superconducting cables. There are still many basic technical issues in the cable industry that have not been solved, and there is not a small gap between them and industrialized countries. This is exactly what small and medium wire and cable companies are concerned about. For example, copper-clad aluminum conductor power cables should not be popularized in the end. Whether low-smoke and low-halogen cables exist or not, and how to further promote the use of environmental protection cables, etc., are all problems for cable companies that are puzzling and need to be solved.
We should treat the future market of superconducting cables rationally. Even if China's demand for superconducting cables grows significantly in the future, it will never exceed the usage of ordinary power cables. There are only a few large cable companies in China that can manufacture this kind of high-tech cable products, which is unmatched by ordinary SMEs and can only be viewed by high-tech products.
For industry organizations, instead of spreading the advanced nature of superconducting cables, it is better to spend time guiding companies to develop more practical new products. For enterprises, instead of being onlookers as high-tech products, it is better to develop new products with high technological content and high added value.
