Pressure XLPE cable product demand growth in China in recent years, rapid, doubling every few years demand has become an indisputable fact, less than 1,000 km from 2000 to 2003, 2,370 km to 10,000 km break in 2008, is expected to 2015 annual demand will be more than 20,000 kilometers, which illustrates the next five years or longer period of time in China the demand for high voltage XLPE cable is still in a period of rapid growth.
Far East Cable Co., Ltd. since 2003 with CCV (catenary) successfully cross-linking technology development and production of high voltage 110kV XLPE cable has been thousands of miles customers use the product delivery. In 2006 the company also introduced today the most advanced 220kV and 500kVCCV (catenary) high-voltage power cable production line, and after digestion and absorption, has successfully produced nearly a thousand kilometers of high voltage XLPE cable to deliver the user into operation, the product widely used in Jiangsu, Shanghai, Beijing, Zhejiang, Fujian, Jiangxi, Anhui, Shandong, Henan, Hebei, Hunan, Yunnan, Shaanxi, Liaoning, Heilongjiang and power users, and more than 300 km of high voltage cables exported to Singapore, India, Angola, Kenya, Equatorial Several countries such as Liberia, widely favored by users.
Today CCV (hanging chain) cross-linking production technology, production equipment and testing means not only fully equipped, and use of advanced control technology, reliable drape control, large length of the cross-linking heating and cooling section paragraph, accurate measurement of line tension control and large synchronous rotating traction control technology, making CCV (hanging chain) cross-linked high-voltage XLPE cable manufacturing process technology and product quality in the past VCV (vertical) technology on the basis of a great upgrade. According to State Home Appliances Cables Quality Supervision, Inspection Center and the Guangdong Power Grid Corporation in November 2008 by 17 national high-voltage XLPE cable manufacturing random sampling of 17 110kV400mm2 ~ 1000mm2 cable sample test results show that: CCV (hanging chain) than VCV ( vertical) cross-linking process of production high voltage XLPE cable insulation eccentricity were better more controllable.
CCV (hanging chain) production of high-pressure cross-linking process Power cable The main feature lies in:
1. Roundness is good. As the cross-linking pipe and cooling pipe is relatively long, not Other Constraints, so thick insulated cables without the stress and the steering wheels that are not yet fully insulated from the cooling effect by the force and deformation.
2. Insulation even fully crosslinked. As a result of conductor preheating and appropriate cross-linking temperature, avoid excessive temperature conditions in the cross-linking, so thick insulating layer of insulation and external temperature shrink even more fully cross-linked, more conducive to improving quality and insulation thermal insulation stress.
3. Production more efficient. Relatively the same size cable production speed to be fast, efficient, one-third higher than average.
4. Safe and cost effective. Use CCV (hanging chain) process of production of high voltage XLPE cable as better performance, run more secure, long life, which cost more advantages.
With the continuous progress of science and technology of today, the Far East Cable Co., Ltd., following the United States, Europe and Japan after the world’s developed countries take the lead in the domestic application of CCV (catenary) technology to produce high voltage XLPE cable, and successfully in the domestic market widely used, widely welcomed by customers, business development and therefore more dynamic.
