The invention has advanced and practical process and less investment. The shielding flexible cable with the two-core semicircular conductor for the communication power supply manufactured by the invention has the advantages of good roundness, smaller outer diameter, good heat dissipation, small occupied space for cable laying and low manufacturing cost of the cable.
Description
Technical field
The present invention relates to a kind of manufacturing process of power cable, especially communication power supply is with the manufacturing process of the shielded flexible cable with two core semicircular conductors.
Background technology
The existing communication power supply uses cable to be mostly two cores, and the conductor of its heart yearn is generally circle, for guaranteeing the roundness of cable; Be employed in the manufacturing process of adding filling member in the cable core, cause the finished cable external diameter bigger, poor radiation; Cable laying takes up room greatly, and the manufacturing cost of cable also increases.Communication power supply can not add filling member with the shielded flexible cable with two core semicircular conductors also can make cable keep good roundness, and the finished cable external diameter is less, and thermal diffusivity is good, and it is little that cable laying takes up room, and the manufacturing cost of cable reduces.Therefore, provide a kind of communication power supply very necessary with the manufacturing process of shielded flexible cable with two core semicircular conductors.
Summary of the invention
The purpose of this invention is to provide the manufacturing process of a kind of communication power supply with shielded flexible cable with two core semicircular conductors.
A kind of communication power supply provided by the invention mainly comprises manufacture craft, heart yearn manufacture craft, the cabling process of the semicircular conductor of two heart yearns with the manufacturing process of the shielded flexible cable with two core semicircular conductors, and each road manufacture craft is such:
The manufacture craft of a, semicircular conductor: form strand by monofilament, form conductor, get into the first road frame winch and mould then according to the order of sequence and carry out multiple strand by a plurality of strands; Mould behind the first road frame winch is a circular die, and the mould behind the later per pass frame winch is the semicircle pinch roller mould for being made up of upper and lower pinch roller all, and the circumferential edge of upper pressure wheel is provided with semi-circular recesses; The circumferential edge of lower pressure wheel is the plane; Conductor is progressively forming semicircular conductor through in the semicircle pinch roller mold process according to the order of sequence, behind last one frame winch and semicircle pinch roller mould, and the semicircular conductor moulding; The tight band of wrapped again one deck is fixed semicircular conductor;
B, heart yearn manufacture craft: the extruded insulation layer is made semicircle heart yearn separately outside two semicircular conductors; The core rod, the die sleeve that extrude mould are semicircle; Core rod and die sleeve angle are controlled at 5-8 °, and the circular arc of semicircle mould is last during the extruded insulation layer, and the plane is following;
C, cabling process: the plane of two semicircle heart yearns is carried out relatively stranded, adopt the pretwist stranding, the stranding lay ratio is controlled at 35-45 doubly, coats belting layer, screen, oversheath successively outside two heart yearns after stranded.
The invention has the beneficial effects as follows: technology is advanced practical, small investment.The communication power supply that adopts the present invention to process is good with the shielded flexible cable roundness with two core semicircular conductors, external diameter is less, and thermal diffusivity is good, and cable laying takes up room little, the low cost of manufacture of cable.

Embodiment
Below in conjunction with embodiment the present invention is described further.
With cable RVVZP 0.6/1kV 2*240 is example:
30 on monofilament by line footpath 0.45mm is formed strand, and 48 dish strands (30/0.45mm) are made through 61 frame winches strand.Stranded mode is 3+9+15+21: 3 dish strands on first frame, and direction of lay is a left-hand, stranded mould is circular nylon mould; 9 dish strands on second frame, direction of lay is a dextrad, stranded mould is the semicircle pinch roller mould of being made up of upper and lower pinch roller; The circumferential edge of upper pressure wheel 1 is provided with semi-circular recesses 2, is semicircle pinch roller, and the circumferential edge of lower pressure wheel 3 is plane 4, is the planar shaped pinch roller; 15 dish strands on the 3rd frame, direction of lay is a dextrad, stranded mould also is semicircle pinch roller mould; 21 dish strands on the 4th frame, direction of lay is a left-hand, stranded mould also is semicircle pinch roller mould.Conductor adopts wheeled traction in the strand process again, twists pitch again and is controlled at 190-200mm, and flat height is controlled at 13.50mm, twists later half round conductor moulding again, and the fire-retardant polypropylene band of wrapped again one deck is tightly pricked semicircular conductor.Outside two semicircular conductors, extrude the flame-proof polyvinyl chloride insulating barrier separately then and make semicircle heart yearn; The core rod, the die sleeve that extrude mould are semicircle; Core rod and die sleeve angle are controlled at 5-8 °, and the circular arc of semicircle mould is last during the extruded insulation layer, and the plane is following.Then the plane of two heart yearns is carried out relatively strandedly, adopt the pretwist stranding, laying up pitch is controlled at 1400-1500mm, coats fireproof glass silk ribbon belting layer, soft copper band screen, flame-proof polyvinyl chloride oversheath successively outside two heart yearns after stranded again.
Use the present invention to make communication power supply with shielded flexible cable with two core semicircular conductors; The quantity difference of the strand that the quantity of the monofilament of can be different according to the line footpath of the monofilament of semicircular conductor, forming strand is different, stranded is provided with not the frame winch and the stranded mould of people having a common goal's number, after being twisted into the semicircular conductor of different size more separately the extruded insulation layer process semicircle heart yearn; Carry out the plane of two semicircle heart yearns stranded relatively then; Coat fireproof glass silk ribbon belting layer, soft copper band screen, flame-proof polyvinyl chloride oversheath outside two heart yearns after stranded successively, the communication power supply of promptly processing different size is with the shielded flexible cable with two core semicircular conductors.
