Description
Technical field
The utility model relates to a kind of aluminium alloy conductor cable for shield machine, belong to field of cable technology.
Background technique
In recent years with the continuous improvement of domestic communication condition, massif tunnel digging and metro construction welcome quick hair
In exhibition period, digging equipment is mainly shield machine equipment, and the cable of mating shield machine also uses traditional copper conductor shield electromechanical
Cable, shield machine tens meters of accompanying cable needs or even several hundred rice in tunneling process are pulled back and forth on ground, due to copper
The specific gravity of conductor is bigger, influences cable dead weight, exacerbates cable in the frictional force of ground moving, cable cover(ing) is caused to pass through
Often damage reduces cable service life, while the price of copper is more expensive, promotes cables manufacturing cost, is unfavorable for cable and promotes for a long time.
Summary of the invention
The utility model aim is to provide a kind of aluminium alloy conductor cable for shield machine, replaces traditional copper using aluminium alloy conductor
Conductor is effectively reduced cable self weight, improves cable service life, and the price of aluminium is more cheap, can reduce cables manufacturing cost,
Efficiently solve the above problem present in background technique.
The technical solution of the utility model is: a kind of aluminium alloy conductor cable for shield machine, includes power core conductor, isolation
Layer, power wire core insulation, gnd conductor, semi-conductive adhesive, non-woven fabrics and environmentally friendly chlorinated polyethylene sheath, the power wire core are led
Body, separation layer and power wire core insulation set gradually composition power cable core from the inside to the outside, and separation layer is around power wire core
Outside conductor, power wire core insulation is extruded in outside separation layer；Semi-conductive adhesive, which is extruded in outside gnd conductor, forms wire core；It is dynamic
The quantity of power cable core and wire core is one or more, and the two forms cable core, wrapped non-woven fabrics outside cable core, nothing
Environmentally friendly chlorinated polyethylene sheath is extruded outside woven fabric；Power core conductor and the material of gnd conductor are aluminium alloy conductor.
The aluminium alloy conductor monofilament diameter of the power core conductor and gnd conductor is between 0.2-0.3mm, aluminium alloy
Synnema lay ratio is twisted less than 20 times, twists lay ratio again less than 20 times.
The power core conductor and gnd conductor are the aluminium alloy conductor after annealing.
The beneficial effects of the utility model are: replacing traditional copper conductor using aluminium alloy conductor, the specific gravity of copper is the 3.3 of aluminium
Times, cable self weight is effectively reduced, improves cable service life, the price of aluminium is also the 1/3 of copper, through under measuring and calculating cable overall cost
It is reduced to original 1/5, cable cost is effectively reduced.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: power core conductor 1, separation layer 2, power wire core insulation 3, gnd conductor 4, semi-conductive adhesive 5, non-woven fabrics 6,
Environmentally friendly chlorinated polyethylene sheath 7.
Specific embodiment
Technical solutions of the utility model are described in further detail with embodiment with reference to the accompanying drawing.
A kind of aluminium alloy conductor cable for shield machine includes power core conductor 1, separation layer 2, power wire core insulation 3, ground wire
Conductor 4, semi-conductive adhesive 5, non-woven fabrics 6 and environmentally friendly chlorinated polyethylene sheath 7, the power core conductor 1, separation layer 2 and power
Core insulation 3 sets gradually composition power cable core from the inside to the outside, and separation layer 2 is outside power core conductor 1, power
Core insulation 3 is extruded in outside separation layer 2；Semi-conductive adhesive 5 is extruded in outside gnd conductor 4 and forms wire core；Power electric cable
The quantity of core and wire core is one or more, the two composition cable core, wrapped non-woven fabrics 6 outside cable core, outside non-woven fabrics
Extrude environmentally friendly chlorinated polyethylene sheath 7；Power core conductor 1 and the material of gnd conductor 4 are aluminium alloy conductor.
Between 0.2-0.3mm, aluminium closes the aluminium alloy conductor monofilament diameter of the power core conductor 1 and gnd conductor 4
The twisted synnema lay ratio of gold twists lay ratio less than 20 times less than 20 times again.
The power core conductor and gnd conductor are the aluminium alloy conductor after annealing.
The aluminium alloy conductor annealing process: aluminium bar is during drawing on wire drawing machine, it may occur that hardens, becomes fragile, is
The plasticity for restoring monofilament, keeps good electric property, it is therefore desirable to wire rod made annealing treatment at a certain temperature,
So one section of fixed length twist again after conductor be wrapped in annealing axis on be put into annealing furnace carry out integrally annealed, it is specific as follows:
Step (1): annealing furnace heating temperature is adjusted to 320 DEG C~350 DEG C, handle after making in-furnace temperature reach 350 DEG C by heating
Aluminium alloy is placed in furnace；
Step (2): heat preservation, then the heating temperature of heating element is adjusted to 320 DEG C, keep the temperature 9h~10h；
Step (3): cooling, per hour cooling extent be 15 DEG C~17 DEG C, until drop to 150 DEG C or less come out of the stove it is air-cooled.
After the aluminium alloy conductor annealing, the control of monofilament elongation is 25% or more, and tensile strength control exists: 100-
120MPa。
In practical applications, in the wrapped separation layer 2 of power core conductor 1, separation layer 2 extrudes 3 composition of power wire core insulation
Power cable core extrudes semi-conductive adhesive 5 outside gnd conductor 4 and forms wire core, more power cable cores and wire core at
Cable, outer wrapped non-woven fabrics 6 after stranding extrude environmentally friendly chlorinated polyethylene sheath 7 outside non-woven fabrics 6.
