High voltage cable technology research and development a good beginning - China Wire and cable

High voltage cable technology research and development a good beginning to China high voltage cable technology research and development a good beginning zhangyunlong (date) (month) (year), our country began to implement new imported equipment domestic investment projects shall be approved according to the announcement by the Ministry of Finance in the duty-free imports of domestic investment projects not ( Revision) Overhead conductors, among them, the kV and below, plus or minus kV and below dc cable and kV and below cross-linked polyethylene insulated cable is no longer a duty-free imports. The rules to protect the interests of the domestic cable companies and the development of independent cable technology has important realistic meaning and historical significance. Power supply departments over the years, our country is keen to import foreign wire and cable, and interest in the domestic cable is not big, this is a kind of distorted values of products. Compared with South Korea proud of using the Chinese thoughts, values and a huge gap of our products. Our country medium voltage cross-linking cables have been exported to the Middle East and other regions, as early as s s popularization and application in China. Power supply departments, however, is also in the s, our country has a large number of medium voltage cross-linking cables imported from South Korea, Japan, caused a great impact to the development of the national cable industry. On domestic prices of imported medium-voltage crosslinking cable crosslinking cable market shocks, has been for many years, the domestic cable enterprise suffered huge economic losses. After the s, China began to a large number of applications kV and above high pressure and ultrahigh pressure cross-linking cables, is still all imports. With great enthusiasm foreign investment, the high voltage cable field in China and to the fledgling domestic high voltage crosslinked cable with great blow. So far, our country - kV crosslinking cable manufacturing technology already quite mature. KV and below crosslinking cable already all localization, - kV crosslinking cable has quite a good running records, kV crosslinking cable has passed appraisal and trial run. The country issued no exemption catalogue of imported goods, the scope of three kinds of cable products listed as imported duty-free, cable technology development in China is a positive affirmation and encouragement. Over the past five years, the domestic enterprise constantly declared - kV crosslinking cable can replace imported products, but to little effect. Today, of the provisions of the state can be said to be the round cable companies dream for many years. However, from a new version of the catalog of duty-free imports not prescribed three kinds of products, kV overhead conductors, plus or minus kV dc cable and kV crosslinked polyethylene insulated cable will still keep the import situation. It also puts forward a new task to the cable industry in our country, the next step to enter the extra-high voltage cable field. In fact, our kV overhead conductors, including kV and kV cable manufacturing technology is under continuous development and improvement; Also have several factories in working on kV crosslinking cable, and have achieved gratifying results. Only uhvdc cable, due to the limited use, has not put power r&d. Believe in the near future, our country will have the ample conditions of manufacturing ultra-high voltage cable entering extra-high voltage power cable manufacturing technology.
