Abstract
The invention discloses a manufacturing method for a low-sag soft-aluminum-wire optical fiber composite overhead phase line. The method comprises the following steps that 1) optical fibers are arranged in a stainless steel casing pipe; 2) a fan-shaped aluminum cladding layer is extruded on the outer surface of the stainless steel casing pipe to form an optical fiber unit; 3) fan-shaped soft aluminum wires and the optical fiber unit are simultaneously intertwisted outside a carbon fiber composite core; 4) and at least one layer of fan-shaped soft aluminum wires are intertwisted on an outermost layer.
Description
Technical field
The present invention relates to a kind of manufacture method of aerial condutor of transmission line, the manufacture method of especially a kind of low arc drop, soft aluminium molded line optical phase conductor.
Background technology
At present, the optical phase conductor of existing transmission line is generally to make central reinforce member with single steel wire or steel strand wire, stranded layer be stainless steel tube make the fiber unit of sleeve pipe and the circular aluminum metal wire stranded and make, this optical phase conductor sag is large, sectional area is large, D.C. resistance is large, ampacity is low, wind pressure load is large, surface easily freezes, wave odds large, the self-damping performance is general and corrosion resistance is low, thereby causes phase line easily to be damaged.
Summary of the invention
In order to overcome the deficiency of the optical phase conductor that has transmission line now, the invention provides the manufacture method of a kind of low arc drop, soft aluminium molded line optical phase conductor.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
The manufacture method of a kind of low arc drop, soft aluminium molded line optical phase conductor, comprise the steps: 1) first optical fiber is arranged in the stainless steel sleeve pipe; 2) again stainless steel sleeve pipe appearance is extruded to fan-shaped aluminium coating layer and make fiber unit; 3) then simultaneously stranded fan-shaped annealed aluminum wire and fiber unit outside carbon fiber complex core; 4) finally at the outermost layer fan-shaped annealed aluminum wire of stranded at least one deck again.
Preferably, described fan-shaped annealed aluminum wire be the conductance annealed aluminum wire that is 63%IACS owing to having adopted technique scheme, the present invention has following beneficial effect:
With common optical phase conductor, compare, in the situation that external diameter is equal, low arc drop, soft aluminium molded line optical phase conductor reduced sag, increased the aluminium sectional area, reduced D.C. resistance and AC resistance is also less, improved operating temperature, ampacity also greatly improves, and the intensity of wire is had no significant effect.On the other hand, in low arc drop, soft aluminium molded line optical phase conductor and the prismatic situation of ordinary optic fibre composite aerial phase line, low arc drop is soft, the external diameter of aluminium molded line optical phase conductor can reduce 10%, and smooth surface, blast in service meets less, surface is not-easy-to-freeze, the occurrence probability that can reduce to wave.Strand and strand due to low arc drop, soft aluminium molded line optical phase conductor is that face contacts again, can consume more vibrational energy when aeolian vibration, be that the self-damping performance is also better, and because stainless steel sleeve pipe appearance is extruded with the aluminium coating layer, making the aluminium coating layer of stainless steel sleeve pipe appearance and surface that fan-shaped aluminum steel contacts with each other between the two is same metal, can not form potential difference, even adhere to condensed state water, can not form electric current between same metal, aluminum steel can not be corroded yet.Borrow in above advantage, but the useful life of extended fiber composite aerial phase line.

Embodiment
Below according to embodiment, the present invention is described in further detail.
With reference to Fig. 1, the manufacture method of a kind of low arc drop of the present invention, soft aluminium molded line optical phase conductor comprises:
1) first optical fiber 3 is located in stainless steel sleeve pipe 2;
2) again stainless steel sleeve pipe 2 appearances are extruded to fan-shaped aluminium coating layer 5 and make fiber unit 4;
3) then at stranded fan-shaped annealed aluminum wire 6 of outer while of carbon fiber complex core 1 and fiber unit 4;
4) finally at the outermost layer fan-shaped annealed aluminum wire 6 of stranded at least one deck again.
As shown in Figure 1, a kind of low arc drop, soft aluminium molded line optical phase conductor, by carbon fiber complex core 1, conductor and fiber unit 4, formed, core 1 arranged outside in carrying has conductor and fiber unit 4, described fiber unit 4 outer surfaces be extruded with fan-shaped aluminium coating layer 5 and with the stranded formation internal layer of fan-shaped aluminum metal lines, and be wound with at least fan-shaped aluminum metal lines 6 of one deck outside internal layer.Conductor adopts full annealing aluminium, the annealed aluminum wire that its conductance is 63% work ACS.
With common optical phase conductor, compare, in the situation that external diameter is equal, low arc drop, soft aluminium molded line optical phase conductor reduced sag, increased the aluminium sectional area, reduced D.C. resistance and AC resistance is also less, improved operating temperature, ampacity also greatly improves, and the intensity of wire is had no significant effect.On the other hand, in low arc drop, soft aluminium molded line optical phase conductor and the prismatic situation of ordinary optic fibre composite aerial phase line, low arc drop is soft, the external diameter of aluminium molded line optical phase conductor can reduce 10%, and smooth surface, blast in service meets less, surface is not-easy-to-freeze, the occurrence probability that can reduce to wave.Strand and strand due to low arc drop, soft aluminium molded line optical phase conductor is that face contacts again, can consume more vibrational energy when aeolian vibration, be that the self-damping performance is also better, and because stainless steel sleeve pipe appearance is extruded with the aluminium coating layer, making the aluminium coating layer of stainless steel sleeve pipe appearance and surface that fan-shaped aluminum steel contacts with each other between the two is same metal, can not form potential difference, even adhere to condensed state water, can not form electric current between same metal, aluminum steel can not be corroded yet.Borrow in above advantage, but the useful life of extended fiber composite aerial phase line.
Obviously, the above embodiment of the present invention is only for example of the present invention clearly is described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make on the basis of the above description other multi-form variation and changes.Here can't give all execution modes exhaustive.Every still row in protection scope of the present invention of apparent variation that technical scheme of the present invention amplifies out or change that belong to.
