Abstract
The utility model provides a low wind noise optic fibre composite overhead ground wire, includes stainless steel sleeve pipe optical fiber unit and the aluminium clad steel wire of transposition together with optical fiber unit, at the fan-shaped aluminum alloy line of different thickness alternate settings of stainless steel sleeve pipe optical fiber unit and the outer cladding of aluminium clad steel wire. The utility model discloses owing to coated the fan-shaped aluminum alloy wire of the alternate setting of different thickness outside stainless steel sleeve fiber unit and the aluminium clad steel wire, make the compound overhead earth wire surface of optic fibre change the smooth situation of rounding, become unsmooth, weakened the noise that the ground wire produced after being blown in the air, reduced wind and made an uproar, reduced the noise interference to surrounding environment, the effect ideal, the cost is lower.
Description
Technical field
The utility model relates to a kind of overhead ground wire of transmission line, especially OPGW.
Background technology
The wind of OPGW is made an uproar and is meant the ear-piercing noise that ground wire is produced later on by wind aloft, and its power is relevant with the level and smooth situation of rounding on the surface of OPGW.The line surface is level and smooth more, and wind is made an uproar strong more, and is big more to the noise jamming of surrounding environment.The existing fiber composite overhead ground wire generally adopts round line concentric stranding, and the cross section of line is circular, and the surperficial rounding of line is level and smooth, and wind is made an uproar by force.Therefore,, need take measures to change the level and smooth situation of rounding on line surface, weaken wind and make an uproar, to reduce noise jamming to surrounding environment for the OPGW in the transmission line that sets up in the residential block.For the wind that weakens OPGW is made an uproar, common online surperficial winding screw shape bar changes the level and smooth situation of rounding on the surface of line.But it is higher to do cost like this, and it is also undesirable to reduce the wind effect of making an uproar.
Summary of the invention
In order to overcome the deficiency of existing fiber composite overhead ground wire, the utility model provides a kind of low wind din-light fine composite overhead ground wire.
The fine composite overhead ground wire of a kind of low wind din-light that the utility model provides; Comprise stainless steel sleeve pipe fiber unit and, outside stainless steel sleeve pipe fiber unit and aluminium-clad steel wire, coat the fan-shaped aluminium alloy wire of the alternate setting of different-thickness with the stranded aluminium-clad steel wire of fiber unit.
The beneficial effect of the utility model is: owing to outside stainless steel sleeve pipe fiber unit and aluminium-clad steel wire, coated the fan-shaped aluminium alloy wire of the alternate setting of different-thickness; The level and smooth situation of rounding that made the OPGW surface modification becomes uneven, has weakened the noise that ground wire is produced later on by wind aloft; Having reduced wind makes an uproar; Reduced the noise jamming to surrounding environment, satisfactory for result, cost is lower.
Description of drawings
Fig. 1 is the cross sectional representation of the utility model.
In Fig. 1,1, thick fan-shaped aluminium alloy wire, 2, stainless steel sleeve pipe fiber unit, 3, optical fiber, 4, aluminium-clad steel wire, 5, thin fan-shaped aluminium alloy wire.
Embodiment
With reference to Fig. 1, the interior stainless steel sleeve pipe fiber unit 2 of establishing optical fiber 3 is stranded with aluminium-clad steel wire 4, coat the thick fan-shaped aluminium alloy wire 1 and thin fan-shaped aluminium alloy wire 5 of alternate setting again in its outside, promptly process the utility model.
Claims (1)
1. the fine composite overhead ground wire of one kind low wind din-light; Comprise stainless steel sleeve pipe fiber unit and, it is characterized in that outside stainless steel sleeve pipe fiber unit and aluminium-clad steel wire, coating the fan-shaped aluminium alloy wire of the alternate setting of different-thickness with the stranded aluminium-clad steel wire of fiber unit.
