Description

technical field [0001] The invention relates to an epoxy resin composition, in particular to a matrix resin composition for a resin-based fiber-reinforced composite mandrel for overhead wires. The present invention also relates to a method of using the above-mentioned resin composition. Background technique [0002] As the carrier of power transmission, overhead transmission wire occupies an extremely important position in the transmission line. For a long time, aluminum steel cored wire (ACSR) has been mainly used for overhead conductors. [0003] With the continuous advancement of material technology, people tried to use organic composite materials instead of metal materials to make the core material of wires at the end of the 20th century, and developed a new type of composite core wire (ACCC wire). Compared with traditional overhead wires, the new wires have high strength, high electrical conductivity, large carrying capacity, high operating temperature, small linear e...
