Abstract
The invention discloses an optical fiber unit used for an optical fiber composite overhead phase line. The optical fiber unit comprises a plurality of optical fibers and a stainless steel sleeve which is arranged on the outer surfaces of the optical fibers in a surrounding mode. The stainless steel sleeve is filled with optical fiber ointment, and the cross section of the stainless steel sleeve is in a round shape or in a fan shape.
Description
Technical field
The present invention relates to a kind of fiber unit of transmission line of electricity, in particular for the fiber unit of optical phase conductor.
Background technology
At present, the optical phase conductor of existing transmission line of electricity be generally with stainless-steel tube make the fiber unit of sleeve pipe and aluminum metal lines stranded and make, this optical phase conductor sectional area is large, direct current resistance is large, current-carrying capacity 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 of electricity now, the invention provides a kind of fiber unit for optical phase conductor.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of fiber unit for contraction special-shaped corrosion-resistant optical phase conductor, comprise multiply optical fiber, and around the stainless steel sleeve pipe that is arranged on described optical fiber outside surface.
Preferably, be filled with optical fiber ointment in described stainless steel sleeve pipe.
Preferably, the xsect of described stainless steel sleeve pipe is circular or fan-shaped.
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, the contraction special-shaped optical fibre composite aerial phase line increased the aluminium sectional area, reduced direct current resistance and AC resistance is also less, improved running temperature, current-carrying capacity also greatly improves, and the intensity of wire is had no significant effect.On the other hand, in contraction special-shaped optical fibre composite aerial phase line and the prismatic situation of ordinary optic fibre composite aerial phase line, the external diameter of contraction special-shaped optical fibre composite aerial phase line can reduce 10%, and smooth surface, blast in service meets less, and surface is not-easy-to-freeze, the occurrence probability that can reduce to wave.Strand due to the contraction special-shaped optical fibre composite aerial phase line is that face contacts with strand 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 clad, making the surface contacted with each other between the aluminium clad of stainless steel sleeve pipe appearance and fan-shaped aluminum-clad steel wire clad and outer field fan-shaped hard-drawn aluminium wire three is same metal, can not form potential difference (PD), even adhere to condensed state water, can not form electric current between same metal, hard-drawn aluminium wire can not be corroded yet.In view of above advantage, but the serviceable life of extended fiber composite aerial phase line.
The accompanying drawing explanation
Fig. 1 is cross sectional representation of the present invention.
Wherein, 1, sleeve pipe, 2, optical fiber.
Embodiment
Below according to embodiment, the present invention is described in further detail.
As shown in Figure 1, a kind of fiber unit for contraction special-shaped corrosion-resistant optical phase conductor, comprise multiply optical fiber, and around the stainless steel sleeve pipe that is arranged on described optical fiber outside surface.Be filled with optical fiber ointment in stainless steel sleeve pipe 1,
The xsect of stainless steel sleeve pipe 1 is circular or fan-shaped.
With common optical phase conductor, compare, in the situation that external diameter is equal, the contraction special-shaped optical fibre composite aerial phase line increased the aluminium sectional area, reduced direct current resistance and AC resistance is also less, improved running temperature, current-carrying capacity also greatly improves, and the intensity of wire is had no significant effect.On the other hand, in contraction special-shaped optical fibre composite aerial phase line and the prismatic situation of ordinary optic fibre composite aerial phase line, the external diameter of contraction special-shaped optical fibre composite aerial phase line can reduce 10%, and smooth surface, blast in service meets less, and surface is not-easy-to-freeze, the occurrence probability that can reduce to wave.Strand due to the contraction special-shaped optical fibre composite aerial phase line is that face contacts with strand 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 clad, making the surface contacted with each other between the aluminium clad of stainless steel sleeve pipe appearance and fan-shaped aluminum-clad steel wire clad and outer field fan-shaped hard-drawn aluminium wire three is same metal, can not form potential difference (PD), even adhere to condensed state water, can not form electric current between same metal, hard-drawn aluminium wire can not be corroded yet.In view of above advantage, but the serviceable 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 embodiments 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.
