The direction of lay of layer is left-hand, and the direction of lay of the Z-shaped molded line layer of the second aluminium alloy is dextrad.
Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art
1, the utility model is used for the high current-carrying capacity aluminium alloy conductor of overhead transmission line, strengthening core using carbon fiber and
Basalt fibre mixing is twisted, and is filled and be formed with epoxy resin, light-weight, and tensile strength is big, can for aluminium alloy conductor
The skyborne arc sag of conducting wire is effectively reduced, and improves it to boisterous resistivity；It is also set up in addition, reinforcing core outer surface
There is aluminum alloy strip wrapping layer, on the one hand which improves the roughness for reinforcing wicking surface, make itself and outer layer aluminium
Alloy conductor combination is more firm, while also having protection and fixed function to the composite fibre that it is coated, and improves strengthening core
Anti-cracking performance, and then extend the service life of conducting wire.
2, the utility model is used for the high current-carrying capacity aluminium alloy conductor of overhead transmission line, aluminium alloy conductor layer innermost layer
It is twisted using aluminium alloy round wires, is conducive to the buckling performance for improving aluminium alloy conductor, makes it have smaller bending radius；
Outer layer is provided with the Z-shaped molded line layer of two layers of aluminium alloy, and mutually embedding company is secured between each single line, close structure, conductor cross-section utilization rate
