Description
Technical field
The utility model relates to the technical field of cable structure, specially a kind of 1120 aluminium alloy frame hollow wires.
Background technique
While existing middle strength aluminium alloy material Yin Qibipu aluminium intensity improves 50% resistivity only more general aluminium height less than
The electrical distribution field of 4% characteristic at home and abroad is used widely.Strength aluminium alloy and non-thermal in 6XXX system heat treatment type
Middle strength aluminum alloy material to be used based on 1120 aluminium alloys of processing-type.In 1120 nonheat-treatables strength aluminium alloy relative to
In 6XXX system for strength aluminium alloy, because it does not need to be heat-treated, therefore the energy is more saved, and can preferably avoid
Scratch in conducting wire production process.But 1120 aluminium alloy stranded conductors in existing aluminium alloy aerial conductor structure are all aluminium alloy strand
Line, conducting wire entirety pull-off force is lower, and the structure of outer layer round wires causes conducting wire entire outer diameter larger, and windage is larger.
Summary of the invention
In view of the above-mentioned problems, the utility model provides a kind of 1120 aluminium alloy frame hollow wires, conductive layer is not being reduced
The whole pull-off force of conducting wire is increased substantially under the premise of area, and reduces entire outer diameter, and the wind pressure that conducting wire is subject to is effectively reduced
Active force.
A kind of 1120 aluminium alloy frame hollow wires comprising inner core and external twisted layer, it is characterised in that: the outside is twisted
Layer includes the ring structure that at least one layer of molded line is put together.
It is further characterized by:
The inner core is specially high-strength aluminum alloy core；
The specific structure of the inner core include but is not limited to be 1120 aluminium alloy stranded conductor of steel core, 1120 aluminium alloy of carbon fiber core
1120 aluminium alloy stranded conductor of twisted wire or aluminium Baogang core；
The outermost layer of the external twisted layer is specially the ring structure that molded line is put together；
Every layer is ring structure that molded line is put together in the external twisted layer；
Molded line in the external twisted layer include but is not limited to be ladder-shaped or SZ molded line.
After the utility model, high-strength aluminum alloy, zinc-plated steel core, aluminium Baogang core or carbon fiber composite are used
Core is expected as inner core, and outside uses 1120 aluminium alloy monofilament, and the structure of molded line is made in therein one or more layers, is not subtracting
The whole pull-off force of conducting wire is increased substantially under the premise of few conductive layer area；Because wire diameter is obvious using molded line structure
Reduce, according to conducting wire wind pressure calculation formula:
F=(1/2) * ρ * V2*D*CFX
The Action of Wind pressure power that F --- --- is subject on conductor, N
ρ --- --- atmospheric density, kg/m3
V --- --- wind speed, m/s
D --- --- diameter of wire, m
CFX--- --- wind resistance coefficient
It is recognised that the Action of Wind pressure power that conducting wire is subject to can be effectively reduced in wire diameter after becoming smaller；
To sum up, the whole pull-off force of conducting wire is increased substantially under the premise of not reducing conductive layer area, and is reduced whole
The Action of Wind pressure power that conducting wire is subject to is effectively reduced in external diameter.
