Abstract
FIn the power capacity increasing retrofit project of 220 kV A,B and C power transmission lines from Daba to Qingtongxia in Ningxia,in order to solve the problems of the core rod internal shrink,the core rod fracture,the conductor loose strand and the conductor outer aluminium strand damage in the installation of JRLX/T-350/40 carbon fiber compound core aluminium conductor.Through analyzing the structure and characteristic of the conductor,using the methods of the shorten ing laying conductor section,dispersing crimping,changing the technique of the conductor joint and adopting large wheel diameter stringing tensioner and paying –out pulley,accomplishes the power transmission lines retrofit project with high quality.The result shows that the technology fully satisfies the installation request of carbon fiber compound core aluminium conductor,the transmission capaci ty of lines and the ability to resist risk increase doubly under the accident improved,satisfy the need of safeandsteadypowersupply ofthepowergrid.关键词
