On March 19, 2008 ～ 21 days, committee of technology of standardization of countrywide wire cable annual meeting was held smoothly in Shanghai 2007. The conference examined 12 states level, include among them times those who get the attention inside course of study " cable of power of insulation of polyethylene of cross-linking of rated voltage 500kV and its accessory " .
" cable of power of insulation of polyethylene of cross-linking of rated voltage 500kV and its accessory " put forward by association of industry of Chinese electric equipment, committee of technology of standardization of countrywide wire cable provides system to decide, draft. This is our country reach its accessory to establish national standard to cable of power of insulation of 500kV cross-linking polyethylene first. The sense that makes a standard depends on maintaining national interest, protect cable of manufacturer of broad line cable, wire to use the profit of business, do a foundation to work for safety of national electrified wire netting. Regard extrahigh voltage as the professional firm of cable, whole journey of cable of 10 thousand horses participated in this standard draft, investigate the work, it is one of main units of the standard that draft. It is reported, " cable of power of insulation of polyethylene of cross-linking of rated voltage 500kV and its accessory " national level is cent " accessory of cable of experiment method and requirement, power, power cable " 3 parts.
National economy high speed, persistent development, accelerated electric power to build the development pace of the career, the application of cable of cross-linking of high pressure, superhigh pressure is wider and wider. Current, domestic company already can produce cable of cross-linking of 110kV, 220kV, but 500kV cross-linking cable has not enter commercial stage of production, domestic place needs 500kV cross-linking cable to need to be imported from abroad, 500kV cross-linking cable is homebred change already became urgent matter.
Top-ranking enterprise sells a level. Of the standard contend for be the market actually. The national standard that can make a trade even international standard, it is highest pursuit to each enterprise. In main body technology equipment standard achieves the premise with top-ranking international to fall, cable of 10 thousand horses passes the formulate that takes an active part in national level, commanding elevation of industry of race to control, revealed the technical actual strength of the enterprise, also make pace of industry standard and technical development speed, own innovation consistent, true implementation leads industry technology to develop way with the standard.
