Abstract
A novel photoelectric combined cable belongs to a combined cable used for simultaneously transmitting optical signals and civil low-voltage electric power to blocks and rural resident users. The cable arranges a sheath metal reinforcement, two insulating copper wires, and a PBT loose sleeve into a lattice shape for SZ stranding so as to form a cable core, and insulating waterproof cable paste is filled around the cable core and in gaps. A plurality of optical fibers and optical fiber paste is arranged in the PBT loose sleeve. The cable is formed by longitudinally covering a metal combined tape on the cable core and extruding a polyethylene sheath at the outer side. The cable rearranges the quantities and positions of materials including the insulating copper wires, the PBT loose sleeve, the sheath metal reinforcement, and the like, thereby reducing the kind and quantity of the materials applied, reducing production cost, reducing cable external diameter and weight, and is good for construction laying.
Description
Affiliated technical field:
The utility model relates to a kind of compound cable that is applicable to block and urban residents user's while transmitting optical signal and civilian low-voltage power.
Background technology:
Optoelectronic composite cable in the market is according to the stranding pattern of common layer-stranding cable two insulated copper cash and loose sleeve pipes of some PBT and presumable gasket for packing SZ form to be stranded in around the metal reinforcement; And around vertical bag polyester belt, metal compound belt, and then extrude pe sheath.This kind optoelectronic composite cable, because according to common layer-stranding cable pattern stranding, material therefor kind, quantity are more, and production cost height and cable external diameter are bigger than normal, and weight is big, is unfavorable for laying of cable.
Summary of the invention:
Various with material in order to overcome existing optoelectronic composite cable production, cost height and cable be big and heavy to be unfavorable for the deficiency of laying.The utility model provides a kind of novel photoelectric composite rope.This kind optoelectronic composite cable can reduce material category and quantity, and the cable external diameter is reduced, and provides cost savings and can be beneficial to engineering to lay.
The scheme that the utility model solves its technical problem is: become the sphere of movements for the elephants pattern to carry out the stranded composition cable core of SZ 1 sheath metal reinforcement, 2 insulated copper cash and 1 PBT pine sleeve arrangement, and around cable core and the gap fill the insulated type cable cream that blocks water.Secondly extrude the final stranding of pe sheath to the vertical genus composite band covered with gold leaf of cable core and in the outside.Wherein the copper cash in the insulated copper wire adopts single filled circles copper cash or annealed copper wire.This kind solution is reset quantity, the position of sheath metal reinforcement, insulated copper wire, PBT pine sleeve pipe etc., arrange, and does not adopt gasket for packing.And replace the insulating effect of polyester belt with the insulated type cable cream that blocks water.So just make the use kind and the quantity of material reduce, production cost reduces, and also impels final cable external diameter to reduce, and weight saving has made things convenient for engineering to lay.
The beneficial effect of the utility model is, reduced the use kind and the quantity of producing material, reduced production cost.Final cable external diameter reduces, and weight saving has made things convenient for engineering to lay.
Description of drawings
Below in conjunction with Figure of description the utility model is further specified.
Fig. 1 is the utility model cross sectional representation
1. optical fiber among the figure, 2.PBT pine sleeve pipe, 3. optical fiber cream, 4. block water cable cream, 5. insulated copper wire, 6. metal compound belt, 7. pe sheath, 8. sheath metal reinforcement of insulated type.
Embodiment
At optical fiber described in Fig. 1 (1), optical fiber cream (3), place PBT pine sleeve pipe (2), said insulated copper wire (5), PBT pine sleeve pipe (2), sheath metal reinforcement (8) are arranged in the cable core of sphere of movements for the elephants pattern.The said insulated type cable cream (4) that blocks water is filled in around the cable core and the gap.Said metal compound belt (6) is coated on around the cable core.Said pe sheath (7) extrudes in metal compound belt (6) all around.
During production, at first with some optical fiber 1 at the core rod that gets into extruder die on the secondary coating production line on the secondary coating production line with the drawing tension unwrapping wire of certain speed, in core rod, have spindle that optical fiber cream 3 is sprayed on around the optical fiber 1.Subsequently at the mould outlet place, plastic extruding machine is extruded the PBT material of molten condition around optical fiber 1 and optical fiber cream 3, and along with tractive effort fast moves forward, the PBT material of molten condition forms the loose sleeve pipe 2 of PBT in the quick crystallisation by cooling sclerosis of hot water storgae and cold rinse bank.
Secondly; With copper cash at the core rod that gets into extruder die on the secondary coating production line on the secondary coating production line with the drawing tension unwrapping wire of certain speed; At the mould outlet place, plastic extruding machine is extruded the polyethylene material or the polyvinyl chloride material of molten condition around copper cash subsequently, along with tractive effort fast moves forward; The polyethylene material of molten condition or polyvinyl chloride material form insulated copper wire 5 in hot water storgae and the quick crystallisation by cooling sclerosis of cold rinse bank.
Once more; With metal reinforcement at the core rod that gets into extruder die on the secondary coating production line on the secondary coating production line with the drawing tension unwrapping wire of certain speed; At the mould outlet place, plastic extruding machine is extruded the polyethylene material of molten condition around metal reinforcement subsequently, along with tractive effort fast moves forward; The polyethylene material of molten condition forms sheath metal reinforcement 8 in hot water storgae and the quick crystallisation by cooling sclerosis of cold rinse bank.
The 4th, 5,1 sheath metal reinforcement 8 of 1 PBT pine sleeve pipe 1,2 insulated copper cash is twisted into cable core with certain twisting pitch on the SZ production line, and around cable core and the gap fill the insulated type cable cream 4. that blocks water
The 5th, with having filled the block water cable core of cable cream 4 of insulated type, on the sheath production line with certain laying tension traction unwrapping wire.Before getting into the extruder die core rod, around cable core, vertically coat layer of metal composite band 6.Pass again subsequently the extruder die core rod to mould mouth place by plastic extruding machine with the polyethylene sheath material of molten condition extrude in around form pe sheath 7, the preforming cable is and then by the final stranding of cooling in quick traction to the cold rinse bank.
This kind cable is reset quantity, the position of materials such as sheath metal reinforcement, insulated copper wire, optical fiber loose tube, arrange, and does not adopt gasket for packing.And replace the insulating effect of polyester belt with the insulated type cable cream that blocks water.So just make the use kind and the quantity of material reduce, production cost reduces, and also impels final cable external diameter to reduce, and weight saving has made things convenient for engineering to lay.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
