Description
Technical field
The present invention relates to field of cable technology, a kind of method being specifically related to cable copper wire twisted synthesizing cable.
Background technology
So-called stranded, it is simply that by several root same diameter or the single line of different-diameter, by certain direction and certain
Rule twists together, and becomes an overall stranded core.When stranded wire uses directly as electric wire, the most naked strand
Line, such as copper stranded conductor, aluminum stranded conductor and steel strand wires etc., for overhead transmission line and electrical equipment connecting line；Stranded wire is as used
When making the conductor of insulated wire cable, the most stranded core, belong to the key component of insulated wire cable.Twisting process is
An important step in bare wire and insulated wire cable production, is a base widely used in electric wire production technology
This technique.
Cable is used to transmit electric energy or control signal.Power equipment electricity consumption majority is to use polyphase source, thus electric
Power cable is multicore, the three-core cable of conventional three phase mains or quad (wherein having a core as ground wire).Control cable
Being mainly used for the circuit of control equipment, the radical that controlling circuit needs is usually a lot, therefore controls cable and does often
Become multicore.The most easy to use, economical, and to using the three-core cable stranding of three phase mains power transmission together, can
So that three-phase magnetic field cancellation, reduce loss.Therefore, in cabling procedure, it is by two cores, three cores, the insulation of even tens
Core twists together.Composition multicore cable.This by insulated wire cores by the stranded technical process of certain rule, including
The filling in space and band process on stranding between core time stranded, be called stranding.
During stranding, the stranded form of insulated wire cores is to use concentric layer regular stranded, the stranding that insulated wire cores diameter is identical
Being called symmetrical stranding, what in insulated wire cores, diameter was different is called asymmetric stranding.
Although the cable that the insulated wire cores of radical twists together as required, economy easy to use, but some cable is
Not stranding, such as high tension cable etc., this is heavy in order to avoid structure is too big and reason in technical equipment, is manufactured into single
Cable.
Stranding is to be carried out stranded for becoming cable in certain direction with certain rule by several root insulated wire cores or unit group
The process of core.Stranding is also stranded, in cabling process in addition to stranded, further comprises that filling, band be wrapped, copper strip shielding around
The techniques such as bag and steel-tape armouring.
At recent two decades, the cable used by China public place and skyscraper is substantially all as copper core conductor low-smoke low-halogen
Or low-smoke halogen-free inflaming-retarding cable, and copper resource belongs to shortage goods and materials in China, 70% from import, copper valency since particularly 2005
Remain high always.In order to ensure for the safety of electric line, again can saving copper resource, attenuating cost of investment, therefore
Invention proposes a kind of new method using cable copper wire twisted synthesizing cable.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that the side of a kind of cable copper wire twisted synthesizing cable
Method, it both can guarantee that the safe operation for electric line, again can saving copper resource, reduce cost of investment.
For achieving the above object, the present invention uses following manufacturing step:
1), copper monofilament draws: at normal temperatures, utilize wire drawing machine to pass through together or the nib of several drawing die so that it is to cut
Face reduces, length increases, intensity improves；
2), monofilament annealing: copper monofilament be heated to carry out at a temperature of certain stranded；
3), the strand system of conductor: conductor wire core is taked that multifilament is stranded to be formed；
4), insulating exruded: to use and extrude solid type insulating barrier；
5), stranding: use without back twist mode, be circular by cable twisting；
6), sheath: be divided into and extrude sheath (separation sleeve) and wrapped sheath (bed course)；
7), oversheath: utilize extruding machine directly to extrude plastic sheath.
Preferably, in described step 2, heating-up temperature is: 460～500 DEG C, improves the tough of monofilament in the way of recrystallization
Property, reduce monofilament intensity, to meet the electric wire requirement to conductor wire core；Annealing operation is it is crucial that stop the oxygen of copper wire
Change.
Preferably, the strand of described step 3 conductor has been made as improving the pliability of electric wire, in order to laying installation, and
Conductor wire core stranded in form, can be divided into rule stranded and irregular stranded.The irregular stranded bundle strand, multiple with one heart of being divided into again
Strand, special stranded etc..
Preferably, by circular for the cable twist forming degree being ensure that cable in described step 5, reduce outside cable
Shape.
Preferably, described step 6 sheath is to protect insulated wire cores not hindered by armouring institute lump, and wrapped bed course replaces tying up
Band and cabling procedure are Tong Bu carried out.
Preferably, described step 7 oversheath is the structural portion protecting the insulating barrier of electric wire to prevent environmental factors from corroding
Point.The Main Function of oversheath is to improve the mechanical strength of electric wire, the protection against the tide of anti-chemical burn into, waterproof people, prevention cable
The abilities such as burning.
Stranding direction of lay of the present invention have left-hand and dextrad point, district's method for distinguishing is identical with stranded core, will insulate
After core stranding, horizontal positioned eyes front, if left-handed for left-hand, dextrorotation is dextrad, and cable outermost layer stranding should be dextrad.
In process of production facing to the front end (i.e. unwrapping wire end) of wire twisting machine or cable-former, cage is to turn clockwise, the core twisted out
For dextrad, it is reversed left-hand.
After using said method, the invention have the benefit that
1), flexibility is good: owing to electric wire uses under different occasions, current-carrying capacity differs, and cross-sectional area of conductor also has greatly
Have little, along with conductor cross-section increase, conductor diameter increases the most therewith, make conductive line bends occur difficulty, if use many little directly
The single line in footpath is stranded, it is possible to improve the crooking ability of wire, it is simple to the processing and manufacturing of electric wire and mounting and installation.
2), good stability: many single lines in certain direction and the stranded stranded core of certain rule, due at twisted wire
In the position of each single line be in the elongation zone on twisted wire top and the compressional zone of the bottom of twisted wire the most in turn, when twisted wire two ends to
During lower bending, extending force and compression stress that every single line is subject to are the most equal, and single line will not produce elongation and compression, and twisted wire also will not
Deform.
3), good reliability: make the conductor of electric wire of single line, easily lacked by generation in discontinuity of material or manufacture
Falling into and affect the reliability of single electrical core, with the stranded core of many single lines, such defect is just disperseed, will not
Focusing in the certain point of wire, the reliability of wire is much better than.Such situation is particularly evident in the joint of wire.
4), intensity is high: the single line of same cross-sectional sizes is compared with many twisted wires, and the strength ratio of twisted wire is with the single line in cross section
Intensity wants height.
