Description
Technical field
The present invention relates to a kind of power cables, and in particular to a kind of steel wire armored power cable and its processing method.
Background technology
Current power cable does not use generally steel wire to carry out armouring in armouring, it is caused to protect intensity low, is easy damage
It is bad.
In addition, even if carrying out armouring using steel wire, the steel wire nominal diameter of use is all 2.5mm hereinafter, due to steel wire armour
Dress, which focuses primarily on, carries out wire armoring on cage winch, each draw drum of cage winch all has back twist function, and steel wire is in armouring process
In do not twist, production Technology is more ripe, and product quality is guaranteed.But armouring wire nominal diameter is more than or equal to
When 2.5mm, conductor assembly outer diameter is larger, and cage winch folding and unfolding dish size cannot meet the requirement of product length and bending radius, armouring steel
Wire armoring of the silk nominal diameter more than or equal to 2.5mm is generally placed on disk winch and produces, but because armouring wire internal stress compared with
Greatly, it is loose to easily lead to steel wire for poor quality's control when cable core is also easy to produce snakelike and oversheath after armouring, and oversheath is damaged, and quality is not
It is fully up to expectations.The first and last end of cable core does not have external force constraint, parallel core or the excessive situation of pitch easily occurs, is to generate
The severely afflicated area of serpentine bend, when wire armoring, use stranded steel wire as front and back draught line, can effectively solve wire armoring electricity
The serpentine bend in cable-end portion.
When at present to big specification wire armouring, the mode of production same as minor diameter steel wire is generally used, there are following matter
Measure situation：
1. will appear different degrees of loose on steel wire pull head after disk, easily there is parallel steel wire or the excessive situation of pitch
(general producer using wrapped two layers of non-woven fabrics outside wire armoring, but because of non-woven fabrics insufficient strength, because phase mutual friction can go out after upper disk
Now different degrees of damage does not have effect to the fixation of steel wire)；
2. because steel wire internal stress is larger when wire armoring, on head end wire armoring after disk cable core will produce it is snakelike；
3. wire armoring end-o f-pipe -control is improper when oversheath, cause steel wire more and more loose.

The beneficial effects of the invention are as follows：
The present invention substantially increases the protection intensity of cable, and cable keeps the torsion that steel wire generates complete in armouring
It returns, eliminates the internal stress of armouring wire, will not be deformed because of internal stress after wire armoring, loosely, irregularly, at cable
The first and last end of core does not have external force constraint, by pre- armouring and mends continuous armouring guarantee cable conductor effective length.
Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
Obtain other attached drawings according to these attached drawings.
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is further explained.
Referring to Fig. 1, steel wire armored power cable provided by the invention comprising a cable core, outside cable core from inside to outside according to
It is secondary to be equipped with liner layer 200, steel wire armor layer 300 and serving 400.
Cable core specifically includes 3~5 insulated wire cores 110, filling 120 and band 130,3~5 insulated wire cores, 110 He
Cable core can be formed by filling twisted coated by band 130 of 120 phases.
Liner layer 200 is specially a sheath, is closely extruded on cable core, to be protected to cable core.
Steel wire armor layer 300 is coated on outside liner layer 200, is steel wire winding structure, and the nominal diameter of steel wire
2.5mm or more, it is greatly improved the intensity of cable in this way.
Serving 400 is specially a sheath, is coated on outside steel wire armor layer 300, for fixing steel wire armor layer
300 and all parts in cable are protected.
Implementation based on said program, present invention also provides the processing method of steel wire armored power cable, the processing sides
Method includes the following steps：
(1) 3~5 insulated wire cores 110 and filling 120 are matched and coats to form cable core by band first；
(2) and then by liner layer 200 it is extruded on cable core；
(3) and then armouring is carried out, cable core head end shifts to an earlier date pre- armouring, mended behind end and continue armouring；
(4) 3 turns~4 turns of pretwist will be finally rotated when 400 head end pull head of serving by wire armoring direction, end is kept
Some tension and fixed cable core prevents back twist.
In addition, in step (2)：Liner layer is produced using tubular type is squeezed, and is 1.10 or more with mode coefficient, liner layer closely squeezes
Packet is on cable core.
In addition, the armoured process in step (3) includes following three step：
A wire gauges select, and wire gauge selects steel wire nominal diameter 2.5mm or more；
B raw material winding steel wire lopping uses drum-type take-up lopping to raw material steel wire；
Steel wire after raw material winding steel wire lopping is rotated not back-twisting unwrapping wire or plum blossom lands by c steel wire after-combustion
Unwrapping wire, i.e. steel wire uniformly twist；
Steel wire after after-combustion is carried out wire armoring using disk winch, shifts to an earlier date pre- armouring 5 in cable core head end by d wire armorings
Rice~10 meters (being approximately distance of the 400 process pay off rack of serving to extrusion molding prelocalization frame), wire armoring direction and insulated wire
Core stranding direction on the contrary, steel wire torsion direction when wire armoring direction and steel wire after-combustion are at disk on the contrary, wire armoring pitch with
Steel wire torsion pitch when steel wire after-combustion is at disk is consistent, and wire armoring lay ratio is 8~12.
It (is approximately serving process pay off rack to extrusion molding prelocalization frame that 5 meters~10 meters of continuous armouring should be mended behind armouring end
Distance).
In addition, in step c：Take-up uses 500 type tooling iron pan rotary wire-reelings, and the steel wire after after-combustion is in 500 type tooling iron
Torque is generated on disk, and steel wire after-combustion length is 1.08+10 meters~20 meters of cable core length *.
The application substantially increases the protection intensity of cable, and cable is in armouring by using the implementation of the above method
When, so that the torsion that steel wire generates is returned completely, eliminates the internal stress of armouring wire, will not be generated because of internal stress after wire armoring
It deforms, is loose, is irregular, the first and last end of cable core does not have external force constraint, by pre- armouring and mends continuous armouring guarantee cable
Cable core effective length.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
