October 19, from the East China Power Transmission Engineering Co., Ltd. 1 million KV Datang power plant to send out the project line through. The carbon fiber composite core wire used in this project is the first application of this new material in UHV engineering.
Carbon fiber composite core wire is a new type of overhead transmission line wire, light weight, tensile resistance, thermal stability. However, due to the carbon fiber self-bending, poor torsional performance, easy scattered stocks, pine shares, cast shares and other characteristics, it is very difficult to be successful in the special high-pressure project. In this respect, the company's various departments to mobilize resources, to carry out adequate preparatory work, invited experts on the carbon fiber cable erection Construction Scheme feasibility demonstration, and the project personnel carried out before the construction of the line of safety, quality and technical disclosure. The company according to the characteristics of carbon fiber wire construction, equipped with various types of carbon fiber wire construction equipment to meet the site, and organized a number of carbon fiber wire crimping Construction theory training and practical exercises, to ensure the safety and quality of carbon fiber wire control, controllable, in control.
1 million kv Inner Mongolia Datang Xilin Hot Power Plant Delivery project is a carbon fiber wire used in UHV pilot demonstration project, from Datang Power plant, stop in the Victory 1000kV substation, single loop erection, the length of the line 14 km, the new angle steel Tower 30, many times across provincial road and other special high-voltage lines, construction difficult. More difficult is that the project along the vast grassland, grassland climate change, April wind and snow, cold air, August precipitation, road transport is difficult, October snowflakes, hail no time, for the construction of a lot of difficulties. In addition, a large number of pastoral pastures along the project, the project personnel need to communicate with pastoralists many times, and in the construction process to pay attention to grassland protection. In such adverse circumstances, the project department after six months of fighting, 19th finally successfully completed the final line of the project release pass. The whole project has ensured the external transportation of Inner Mongolia coal energy, and promoted the transformation of Inner Mongolia coal superiority to economic superiority.
