A kind of surface treated clearance type capacity-improving conducting wires, including core 1, core 1 are internal layer aluminum steel 3 and outer layer aluminum steel outside
4, there are gap between the steel core and aluminum steel in core 1, it is coated with lubricant grease 2 resistant to high temperature in gap, conducting wire is existed
Be safely operated under high temperature, due to the presence in gap, while construction when be aided with steel core stringing processing so that conducting wire is completely by steel
Core stress (since the linear expansion coefficient of steel core is only the 1/2 of aluminum steel), for conducting wire in hot operation, arc sag incrementss are smaller, full
The requirement of sufficient route capacity-increasing transformation, core 1 be superhigh intensity galvanized strand wires, internal layer aluminum steel 3 be heat-resisting aluminium alloy molded line or
Soft aluminum molded line, outer layer aluminum steel 4 are heat resistant aluminum alloy wire or annealed aluminum wire, and outer layer aluminum steel 4 is round wires or molded line, 4 surface of outer layer aluminum steel
By blasting treatment, the reflection of light is reduced, it is desirable that reflectivity≤32%, surface treated gap-type conductor have line expansion system
Number is small, meets increase-volume requirement, can be in the case where being changed without head tower, as long as this kind of conducting wire of replacement same size, i.e., reachable
To the requirement of increase-volume 100%, track investment is reduced, while steel core is coated with grease, have the advantages that corrosion resistant, improves making for conducting wire
Use the service life.
Core 1 is twisted by the galvanized steel wire of more superhigh intensitys, and internal layer aluminum steel 3 is heat-resisting aluminium alloy molded line, outer layer
Aluminum steel 4 is round wires or molded line.
