Description
Technical field
The present invention relates to field of cable technology, particularly a kind of hv cable termination processes technique.
Background technology
The manufacture of electric wire is diverse with the mode of production of most of electronic products.Electronic product generally uses
Another part is assembled into parts, multiple parts refill and are made into separate unit product, and product measures with number of units or number of packages.Electric wire is with length
Degree is basic measurement unit.All electric wires are all from the beginning of conductor is processed, in the periphery of conductor layer by layer plus absolutely
Edge, shielding, stranding, sheath etc. and make electric wire product.Product structure is the most complicated, and the level of superposition is the most.
Summary of the invention
It is an object of the invention to provide a kind of hv cable termination easy and simple to handle, in hgher efficiency and process technique.
The technical solution used in the present invention is:
A kind of hv cable termination processes technique, and its innovative point is: sequentially pass through Insulation test, labelling cutting, pyrocondensation cooling,
Labelling is wound around, connect copper sleeve, polishing dedusting, comprehensive be wound around and post processing processes technique to complete hv cable termination, and it is concrete
Step is as follows:
1) Insulation test: before making, need to carry out Insulation test, testing sequence with the megger of the 2500 volts cable to making
For the insulation between phase and phase and between phase and ground, any one of palpus is more than 2500 megaohms and can make, such as any one
Insulation less than 2500 megaohms or lower, then to cut out 1 meter of this cable, then retest, qualified after can make；
2) labelling cutting: first measure required size, carry out labelling, before moving knife, first adjust razor blade for carving tool, make the point of a knife exposed
Maintain an equal level mutually with the thinnest part of skin at this cable, from mark, draw two cuttves in 45 degree of angle modes, make sure to keep in mind not hinder core diagonal cutting pliers
The glass layer peelling off cable sheath and the inside is coordinated with cutter；
3) pyrocondensation cooling: clean the part of set point fingerstall with ethanol cloth, is inserted in a point fingerstall according to the order of core, and strikes tight.
Before this step, must be by earth lead 23# high pressure belt overstriking, to ensure the sealing after dividing fingerstall pyrocondensation, with heat gun to dividing
Fingerstall heats so that it is pyrocondensation.It should be noted that heat from centre to two during heating so that it is air can be got rid of completely, complete with cable
Seal, after point fingerstall cooling and shaping, according to required size, core is blocked；
4) labelling is wound around: from the head of core to a point fingerstall direction, the distance measuring 27 centimetres performs labelling, 23# high pressure belt
Winding position to point upper 2 to the 3 centimetres of end of finger of point fingerstall, during winding, should use half lap from the beginning of 27 centimetres of positions backward
The mode of bag is carried out, back and forth each the most once, two-layer altogether, determine phase sequence according to the color of core, use form and aspect band to be wound around, its method with
It is wound around 23# high pressure belt the same, covers on 23# high pressure belt, but should be noted at 27 centimetres of marks position backward, form and aspect band
With the distance that 3# high pressure belt should have 5-10 millimeter, after form and aspect band is wrapped, must wrap with adhesive tape, the position when the form and aspect end of tape
Put and be wound around to both sides, each 1 centimetre, terminate after returning to centre, peel off the semiconductor layer of core head, to the position of 27 centimetres；
5) connect copper sleeve: according to the size of core, select suitable copper sleeve, when stripping the major insulation of core, should connect than copper
Long 5 millimeters, earth lead then need not, use hydraulic tongs that copper sleeve is crimped, the copper sleeve after pressing must be put forth one's strength with hands and be drawn
Once, check whether steel joint crimps firmly；
6) polishing dedusting: roughly grind with the 80# rubber in special 211K rubber, polishes the semiconductor layer on core dry
Only, then with 320# rubber, this line is carried out fine grinding, by line ground smooth, use 3MCC-3 cable cleaning paper, the line that will have polished
Core scrub；
7) be comprehensively wound around: the core junction that online die semiconductor layer is clean with polishing, use 13# quasiconductor band from centre to
Both sides are wound around, half pressure half, two centimeters, left and right, and the silicone oil edge in cold-shrinkable terminal should be wound by end point in centre
13# semiconductor layer is coated with a circle, and cold-shrinkable terminal, on core, is then inserted in core by remaining uniform application, and position is then at 13# half
The position of conductor layer 3-4 cm backward extracts the support in shrinkage end out, in core front end, with 23# high pressure belt in shrinkage
Terminal is wound with core junction, method same half pressure half, needs in the gap of copper sleeve Yu major insulation to use
23# high pressure belt fills up, thickness as phase line major insulation, on the 23# high pressure belt wrapped, twines with 70# high pressure belt
Around, the same half pressure half that uses, the method covering of two-layer is on 23# high level belt the most altogether；
8) the ready-made cable termination leftover of bolt of cloth is wrapped up, and prevents from making a mess of, making dirty, clears up rubbish, keeps place cleaning.
Beneficial effects of the present invention is as follows:
Present invention process advantages of simple, simple operation, it is suitable for being widely popularized, the cable of production not only transmission effect is good, insulating properties
Preferably, and service life is the longest, it is possible to apply to a lot of field.
