The use of superconducting cables to retrofit existing underground cable systems can reduce total costs by 20%. Therefore, due to its superiority, superconducting cables are a good alternative to conventional cables in the process of upgrading and augmenting urban power grid facilities. According to statistics, the annual demand for cross-linked polyethylene insulated power cables of 10 kV and above in China is approximately 70,000 to 80,000 kilometers. If 5% of its total volume is replaced by superconducting cables, the annual potential demand for superconducting cables will increase. The total volume will reach 3,500 to 4,000 kilometers. With an average of RMB 2 million per kilometer, the potential market is 8 billion yuan. If you increase at a rate of 7.5% per year, the potential market in 2012 will reach 18 billion yuan. If the market share of the product reaches 10%, the annual output value can reach about 1.8 billion yuan. The market for global superconducting cables in 2012 is estimated to be approximately US$1.7 billion. The research and development level of China's high-temperature cables is far from meeting the needs of new markets. China's technology in this area lags far behind advanced countries in foreign countries. Nearly half of the high-temperature cables need to be imported from abroad, while some domestic manufacturers are concentrated in some small factories. Technological development and production capacity are relatively weak. In particular, production and processing are still limited to existing equipment and tooling of cables, and the development of materials has failed to break through the circle of existing cable materials. It is hoped that domestic manufacturers capable of developing high-temperature special cables can assess the situation, develop and popularize high-temperature series cables in light of China's resources, and increase China's level in this technical field to meet the needs of China's high-temperature industries.
