Description
Technical field
The present invention relates to cable production field, specifically a kind of production technology of cable.
Background technology
Cable is typically by several or the cable of similar rope that several groups of wires [every group at least two] are twisted, every group
Mutually insulated between wire, and be often twisted into around a center, whole outside is surrounded by the coating of high-insulation.It is erected at more
In the air or mounted in underground, the bottom, for telecommunication or power Transmission.Cable manufacturing process of the prior art is sufficiently complex and synthesizes
Process conditions are more harsh, cause cable cost higher.
The content of the invention
The invention provides a kind of production technology of cable, to solve above-mentioned technical problem.
A kind of production technology of cable, comprises the following steps：
(1) draw：Under conditions of 30-45 DEG C, using wire drawing machine, stretched mould, copper pole stock is stretched, wire drawing
A diameter of 0.5-1mm；
(2) anneal：Annealed by annealing furnace, annealing temperature is 550-750 DEG C, and annealing time is 50-60mi n, system
Adopted into wire core；
(3) stranding：Cable is made using carrying out process without back twist mode in 3-5 roots conductor wire core, to the cable after stranding
Carry out colligation；
(4) coating：The coated insulation layer on the outside of cable, thickness of insulating layer 1-2mm；
(5) anti-corrosion material is brushed：One layer of anti-corrosion material is brushed in the cable outer surface that step (4) obtains, stands 0.5-1h；
(6) fill：The gap of the cross section of conductor wire core is filled with filler；
(7) coat：A layer insulating is coated in cable surface.
Preferably, in the step (4), the outside of insulating barrier is provided with oversheath, oversheath directly extruded by extruding machine and
Into.
Preferably, in the step (4), while cladding between wire and insulating barrier fill material, the material is poly-
Propylene band or non-woven fabrics.
Beneficial effects of the present invention：
The production technology of this cable of the present invention, pass through one or the mould of several drawing die using wire drawing machine
Hole, reduces its section, length increase, intensity improve, and wire drawing is the first working procedure of each electric wire company, the main work of wire drawing
Skill parameter is to match somebody with somebody mould technology；Annealing operation key is to prevent the oxidation of copper wire, and copper wire core is adopted in the case where being heated to certain temperature,
The intensity that toughness, the reduction wire core that wire core is adopted are adopted is improved in a manner of recrystallization, to meet electric wire to conductor wire
The requirement of core；In order to improve the pliability of electric wire, in order to laying installation, it is twisted that conductor wire core takes more wire cores to adopt
And become the area occupied for reducing wire, the physical dimension for reducing cable, using form is pressed while stranded conductor, make
Typical circular variation is semicircle, sector, shoe and the circle pressed；For multicore cable in order to ensure forming degree, reduce electricity
The profile of cable, it is typically necessary and is twisted as circle.Twisted mechanism and conductor process are similar, because process pitch diameter is larger,
Mostly using without back twist mode, the technical requirements of stranding：Prevent allotype insulation core to turn over and cause the twist and warping of cable；Prevent absolutely
Edge layer is scratched, and most of cable is while stranding with the completion of two other process：One is filling, after ensureing stranding
The rounding of cable and stably；One is colligation, ensures that cable core is not loose；Sheath needs to protect insulated wire cores not to be scratched
Appropriate protection, sheath point are carried out to insulating barrier：Extrude sheath (separation sleeve) and wrapped sheath (bed course), wrapped pad
Layer replaces binding strap is synchronous with cabling procedure to carry out；Oversheath is that the insulating barrier for protecting electric wire prevents what environmental factor from corroding
Structure division, the main function of oversheath is the mechanical strength of raising electric wire, the protection against the tide of anti-chemical burn into, waterproof people, resistance
The only ability such as cable fire, require directly to extrude plastic protective using extruding machine according to the different of cable.
