Abstract
The invention relates to a layer-stranding type outdoor special optical cable cabling process. An optical fiber beam tube, a steel wire and a filling yarn can be cabled by using a cabling machine and a stranding table thereof in the layer-stranding type outdoor special optical cable cabling process. The layer-stranding type outdoor special optical cable cabling process uses the principle: a cable core is cabled by being rotated in a direction through a winding-up unit of the cabling machine, so as to form a stable structure; in the process, the cable core is fixed by using a binding belt; the cable core is prevented from being loosened through a yarn-binding pitch of the binding belt; the yarn-binding pitch ranges from 20 mm to 25 mm; a laying tension of the steel wire ranges from 80 N to 90 N; a laying tension of the beam tube is 1.5 N to 2.0 N; a yarn-binding tension ranges from 4.5 N to 5 N; a winding-up tension ranges from 80 N to 90 N; a stranding pitch ranges from 70 mm to 80 mm; a stranding angle is 7 phi to 8 phi; the diameter of the beam tube ranges from 1.4 mm to 1.9 mm; and the diameter of the filling yarn ranges from 1.4 mm to 1.9 mm. With the adoption of the layer-stranding type outdoor special optical cable cabling process provided by the invention, the technical difficult problem of cabling of an outdoor special optical fiber can be effectively solved; the torsion degree generated in a cabling process is minimum; and no torsion exists on a total length of the optical fiber, so that the optical fiber is not influenced.
Description
Technical field
The invention belongs to the fiber optic cable manufacture technical field, be specifically related to the outdoor special optical cable cabling process of a kind of layer-twisted type.
Background technology
Optical fiber communication is by high-purity SiO
2Make optical fiber with a small amount of high index of refraction adulterant and light material through applying macromolecular material, then the finished product optical fiber that some (1～2160) is above-mentioned is through cover is moulded, the procedure technology processing and manufacturings such as stranded, squeeze jacket, dress armour form practical cable products.In the optical fiber cable manufacture process, the purity of strict control and assurance raw material of optical fibre, so just can produce the optical fiber cable product of function admirable, simultaneously, it also is very important reasonably selecting production technology, optical cable all requires certain stretching in production, installation and operation process, it is a certain amount of remaining long so just to require optical cable to form when beam tube is extruded.Optical fiber enters extruder to emit under certain laying tension, by the tank cooling, can form remaining length at the low temperature tank, and beam tube has very large contraction and forms remaining length at the low temperature tank, and the remaining control long and expressing technique of beam tube is the key factor that determines properties of optical fiber cable.Optical cable extrude the cover mould after, carry out gasket for packing and extrude, then carry out cabling process, high for its stranding index request of outdoor special optical cable, the technical requirement of outward appearance, central reinforce member is strict, and twisting pitch requires directly quality and the transmission performance of the outdoor special optical cable of impact.
Every kind of optical cable has own unique production technology, because exist different performance requirements and structural shape between them, so the each several part material is not quite similar, structure aspects there are differences, so the technological process of production of oneself is arranged in the production run, for outdoor special optical cable, this point is particularly important.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, proposed the outdoor special optical cable cabling process of a kind of layer-twisted type, described process structure rationally, the bundle yarn is even, tension force is suitable, control flow is suitable, and presentation quality is high, smooth, rounding, color and luster evenly, colour mixture not, have boundless market outlook.
Technical scheme of the present invention is: the outdoor special optical cable cabling process of a kind of layer-twisted type, described technique with cable-former and stranded to optical fiber bundle tubes, steel wire and gasket for packing carry out stranding, its principle is: the direction rotation in take-up unit through cable-former makes the cable core cable, become a rock-steady structure, in this process, play fixedly cable core effect with binder, the bundle yarn pitch of binder is so that cable core is not loose, described bundle yarn pitch range is 20-25mm, the steel wire despooling tension scope is 80-90 newton, the beam tube laying tension is 1.5-2.0 newton, and the yarn-binding tension scope is 4.5-5 newton, and the takeup tension scope is 80-90 newton, the twisting pitch scope is 70-80mm, stranding angle is 7-8 π, and the tube bank diameter range is 1.4-1.9mm, and the gasket for packing diameter range is 1.4-1.9mm.
Described gasket for packing pay off rack adopts initiatively unwrapping wire mode.
When changing specification, get back to origin position for stranded.
The present invention has following beneficial effect:
1) the present invention efficiently solves the technical barrier of outdoor special optical cable stranding, and the degree of the reversing minimum that produces in the stranding does not exist on the optical cable total length and reverses, and makes optical fiber unaffected.
2) tension force control of the present invention is accurate, and optical fiber is avoided centrifugal action, and the yield rate of optical cable is high.
3) product surface that utilizes technique of the present invention to make is smooth, and color and luster is even, and it is smooth to receive winding displacement.
4) utilize the transmission performance of the optical fiber that technique of the present invention makes good, temperature characterisitic is high, and properties of optical fiber cable is strong.
Embodiment
Technique of the present invention with cable-former and stranded to optical fiber bundle tubes, steel wire and gasket for packing carry out stranding, its principle is: the direction rotation in take-up unit through cable-former makes the cable core cable, become a rock-steady structure, in this process, play fixedly cable core effect with binder, outdoor special optical cable uses waterstop to make binder, the bundle yarn pitch of binder is so that cable core is not loose, described bundle yarn pitch range is 20-25mm, the steel wire despooling tension scope is 80-90 newton, and the beam tube laying tension is 1.5-2.0 newton, and the yarn-binding tension scope is 4.5-5 newton, the decay of described yarn-binding tension and optical fiber is closely related, and is unsuitable excessive or too small.Tension force is too small, cause easily the bundle yarn loose, cable core is fixing lax, and cause disconnected cable accident in subsequent handling easily, and overtension binder can occur to prick flat ferrule phenomenon, makes the sleeve pipe inner fiber be subject to the effect of stress, producing crooked decay increases, cause quality accident, the takeup tension scope is 80-90 newton, for the 1+5 cable configuration, its twisting pitch scope is 70-75mm, for the 1+6 cable configuration, its twisting pitch scope is 75-80mm, and stranding angle is 7-8 π, the tube bank diameter range is 1.4-1.9mm, and the gasket for packing diameter range is 1.4-1.9mm.For the 1+5 cable configuration, its cable core is outer to be 5.2-5.4mm through scope, and for the 1+6 cable configuration, its cable core is outer to be 5.6-5.8mm through scope.The decay indices of described optical cable is less than 0.02db/km.
The present invention efficiently solves the technical barrier of outdoor special optical cable stranding, and the degree of the reversing minimum that produces in the stranding does not exist on the optical cable total length and reverses, and makes optical fiber unaffected.Tension force control of the present invention is accurate, and optical fiber is avoided centrifugal action, and the yield rate of optical cable is high.The product surface that utilizes technique of the present invention to make is smooth, and color and luster is even.
