Description

A kind of novel photoelectric composite rope

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 is having heavy in section copper cash (10mm ²More than) situation under, its material therefor is of a great variety, cost is high, and its external diameter and substance sharply increase, and is unfavorable for the cable laying operation of cable.

Summary of the invention:

In order to overcome existing optoelectronic composite cable heavy in section copper cash (10mm is being arranged ²More than) situation under produce variously with material, 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: with 2 copper sections is 10mm ²Above insulated copper wire, 2 light unit are arranged in the sphere of movements for the elephants pattern around 1 pe sheath metal reinforcement, and the gap is provided with 4 gasket for packings around its outside again, and carries out the stranded composition cable core of SZ.The insulated type cable cream that blocks water is filled in around the cable core and gap.At last to extruding the final stranding of pe sheath again in the outside after the vertical genus composite band covered with gold leaf of cable core.Around 1 metal reinforcement SZ stranded composition, the loose sleeve pipe number of PBT is 6 at most by some PBT pine sleeve pipes and gasket for packing in wherein said smooth unit, and minimum is 1, and the gasket for packing number is 5 at most, and minimum is 0.Be provided with optical fiber cream and some optical fiber in the every PBT pine sleeve pipe.Copper cash is single filled circles copper cash or annealed copper wire in the wherein said insulated copper wire, and the insulating material of insulated copper wire adopts polyethylene or polyvinyl chloride.Because it is 10mm that the external diameter of this kind light unit approaches copper section ²The thickness of above insulated copper wire is so both are easy to be twisted into cable core.This kind design both can be satisfied the requirement that optoelectronic composite cable has the heavy in section copper cash.The kind and the quantity of producing material are reduced, and 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.

Embodiment

Be arranged in the sphere of movements for the elephants pattern in 2 insulated copper cash (4) described in Fig. 1,2 light unit (7) around sheath metal reinforcement (6); And side clearance evenly is provided with 4 gasket for packings (3) and forms cable core outside it, and the said insulated type cable cream (5) that blocks water is filled in around the cable core and the gap.Said metal compound belt (2) is coated on around the cable core.Said pe sheath (1) extrudes in metal compound belt (2) all around.

In Fig. 2, amount to 6 filler cells metal reinforcement (12) permutation and combination in the said smooth unit and become cable core.Filler cells is made up of gasket for packing (8) in said PBT pine sleeve pipe (9) and the said smooth unit.The number of said PBT pine sleeve pipe (9) is 6 at most, and minimum is 1, and the number of gasket for packing (8) is 5 at most in the said smooth unit, and minimum is 0.Said optical fiber (10) and optical fiber cream (11) are positioned in the PBT pine sleeve pipe (9).

During production, at first with some optical fiber 10 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 11 is sprayed on around the optical fiber 10.Subsequently at the mould outlet place, plastic extruding machine is extruded the PBT material of molten condition around optical fiber 10 and optical fiber cream 11, and along with tractive effort fast moves forward, the PBT material of molten condition forms the loose sleeve pipe 9 of PBT in the quick crystallisation by cooling sclerosis of hot water storgae and cold rinse bank.

Secondly, with gasket for packing 8 in PBT pine sleeve pipe 9 and the light unit on the SZ production line in the light unit metal reinforcement 12SZ be twisted into optical cable core and form the light unit.When stranded, it is at most 6 that the number of PBT pine sleeve pipe 9 is provided with, and minimum is 1, and to be provided be at most 5 to the number of gasket for packing 8 in the light unit, and minimum is 0.

The 3rd; 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 be crystallisation by cooling sclerosis fast in hot water storgae and cold rinse bank, forms insulated copper wire 4.

The 4th; 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 6 in hot water storgae and the quick crystallisation by cooling sclerosis of cold rinse bank.

The 5th; 2 insulated

copper cash

4 and 2 light unit 7 are arranged in the sphere of movements for the elephants pattern around sheath metal reinforcement 6; The gap evenly is provided with 4 gasket for packings 3 and on the SZ production line, is twisted into cable core with certain twisting pitch around its outside, again around the cable core and the gap fill the insulated type cable cream 5 that blocks water.

The 6th, with having filled the block water cable core of cable cream 5 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 2.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 1, the preforming cable is and then by the final stranding of cooling in quick traction to the cold rinse bank.

The structural shape that this kind cable has utilized optical cable core is formed cable core as the light unit and with the heavy in section insulated copper wire with certain positional alignment, and replaces the insulating effect of polyester belt with the insulated type cable cream that blocks water.Adapted to the requirement that heavy in section copper cash optoelectronic composite cable is arranged.Saved the use kind and the quantity of material greatly than the optoelectronic composite cable line of equal specification, impelled production cost to reduce, final cable external diameter is reduced, 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.
