长期以来,我国远程大容量电力输送采用的电线电缆一般以铜线或铝线为导线,不仅耗能大,而且载流量小,由此造成的停电、断电故障时有发生,成为电力工业发展的一大“瓶颈”。而新型碳纤维复合芯导线具有重量轻、热膨胀系数小、强度高、容量大、耐高温、低弛度、耐腐蚀、低线损的特点,是传统导线的理想替代品。 For a long time, the wire and cable used in China’s long-distance high-capacity power transmission generally take copper wire or aluminum wire as the lead wire, which not only consumes large energy but also has small current carrying capacity, resulting in blackouts and power failure failures that have become the development of the power industry A big “bottleneck ”. The new carbon fiber composite core wire has the characteristics of light weight, small thermal expansion coefficient, high strength, large capacity, high temperature resistance, low sag, corrosion resistance and low wire loss. It is an ideal substitute for traditional wire.
