  • Detail

Henan Province started to erect the first carbon fiber composite power cable

now UTM is also increasingly appearing in plastic molding and extrusion laboratories. Zhongwei line is an important transmission line for the west to East power transmission of Xinxiang Power in Henan Province. With the power load increasing year by year, Beiwei line has reached the transmission limit, and the limited transmission line corridor is far from meeting the demand δ The unit of normal stress is MPa. In view of this problem, Henan Electric Power Survey and Design Institute, in combination with the actual situation, adopted the capacity expansion and reconstruction of the old lines without changing the original towers, and adopted the new material of carbon fiber composite core conductor, which opened up a new way to solve the problem of line capacity expansion

construction site

carbon fiber composite core conductor is an ideal substitute for the traditional steel core aluminum stranded conductor at present. The new conductor has high strength, high operating temperature, high conductivity, low sag and large current carrying capacity. After the transformation is completed, the power supply capacity of the line is equivalent to building a new power transmission line. At the same time, it also avoids the problem of new land occupation, saves cost, shortens the construction period, and provides technical support for the future, which can eliminate the problem of graphene sheet convergence, so as to make the plastic formula design and recycling more flexible. It has accumulated valuable experience

according to liuhengfu, the on-site head of Xinxiang Power Supply Company, the total length of the replaced line is 2280 meters. The line passes through 9 iron towers and 6 corners, and also crosses two highways

extended reading: China's first 220kV carbon fiber composite core conductor

since July 26, 2006, China's first 220kV carbon fiber composite core conductor has been successfully operated in Longyan, Fujian Province, the jrlx/t carbon fiber composite core conductor launched by far east Composite Technology Co., Ltd. has been suspended and operated in more than 100 transmission lines in Fujian, Liaoning, Jiangsu, Zhejiang, Yunnan, Shanxi, Tianjin, Shenzhen and other provinces and cities, and has been well operated, which is highly praised by users, Domestic power transmission technology has made great progress. In the same period, Far East Composite Technology Co., Ltd. won the bid for Fujian electric power construction project again

with the continuous growth of power demand, the transmission capacity is required to be larger and larger. In order to solve the problem of improving the transmission capacity of power lines while using the existing iron towers, most fittings, porcelain bottles and other original equipment, and not increasing the land for line corridors, Far East Composite Technology Co., Ltd. continues to promote the strategy of green development and sustainable development, actively develops new products, explores new ways to transform China's electricity and improve the utilization of the original lines, and strives to build a safe, environmental friendly, efficient and energy-saving transmission network. The Far East carbon fiber composite core conductor has the remarkable characteristics of light weight, high strength, low line loss, low sag, high temperature resistance, corrosion resistance, and environmental compatibility. It only uses 50% aluminum, and can increase its service life from 30 years to 80 years, and also saves 50% of the land. The carbon fiber composite core wire has also passed the energy-saving product certification issued by the electric energy (Beijing) Certification Co., Ltd., becoming the only energy-saving wire and cable product recognized by the state in the cable industry, and the enterprise has also won the title of green benchmark enterprise for many consecutive years
