Abstract
The utility model discloses a high-heat-dissipation optical-fiber composite overhead ground wire. The overhead ground wire comprises a center reinforcement, an inner stranded wire layer and an outer stranded wire layer, wherein the inner stranded wire layer consists of a plurality of first electric units and an optical unit; the outer stranded wire layer is stranded outside the inner stranded wire layer and consists of a plurality of second electric units; the optical unit is not in close contact with the center reinforcement, the first electric units and the second electric units; and heat dissipation clearances are reserved at the periphery of the optical unit. The high-heat-dissipation optical-fiber composite overhead ground wire ensures that the optical unit is not stressed, and high-temperature heat has difficulty in being transmitted to the optical unit in case of short trouble of a power line, thereby avoiding communication interruption due to damage of optical fibers.
Description
Technical field
The utility model relates to a kind of heat dissipation type high Optical Fiber composite overhead Ground Wire.
Background technology
Mainly contain two kinds of Optical Fiber composite overhead Ground Wire on the existing market: center type Optical Fiber composite overhead Ground Wire and layer-twisted type Optical Fiber composite overhead Ground Wire, wherein most widely used with the layer-twisted type Optical Fiber composite overhead Ground Wire again.As shown in Figure 1, the layer-twisted type Optical Fiber composite overhead Ground Wire comprises central reinforce member 1, be stranded in central reinforce member 1 interior twisted wire layer 2 outer, that form by a plurality of first electric units 21 and light unit 22, and the stranded outer twisted wire layer 3 that outside interior twisted wire layer 2, by a plurality of second electric units 31, forms.Above-mentioned smooth unit 22 generally comprises stainless steel tube 221, is provided with multifiber 222 in the stainless steel tube 221, and described first electric unit 21 or second electric unit 31 are generally aluminum metal lines, as aluminium-clad steel wire, aluminium alloy wire etc.Owing to be tangent between light unit 22 and central reinforce member 1, first electric unit 21 and second electric unit 31 in traditional layer-twisted type Optical Fiber composite overhead Ground Wire, therefore when power circuit is short-circuited fault, heat of high temperature heat radiation is relatively poor, and optical fiber 222 is easily impaired and cause communication disruption.
Summary of the invention
The utility model purpose is: a kind of heat dissipation type high Optical Fiber composite overhead Ground Wire is provided, its light unit does not all closely contact with central reinforce member, first electric unit and second electric unit, and have the heat radiation gap around the light unit, when having guaranteed that the light unit does not stress, guaranteed that also power circuit is when being short-circuited fault, heat of high temperature is difficult to be transmitted to the light unit, prevents that optical fiber is impaired and causes communication disruption.
The technical solution of the utility model is: a kind of heat dissipation type high Optical Fiber composite overhead Ground Wire, comprise central reinforce member, be stranded in central reinforce member interior twisted wire layer outer, that form by a plurality of first electric units and light unit, and the stranded outer twisted wire layer that outside interior twisted wire layer, by a plurality of second electric units, forms, described smooth unit does not all closely contact with central reinforce member, first electric unit and second electric unit, and the light unit around have the heat radiation gap.
First electric unit of twisted wire layer is an aluminium-clad steel wire in described.
Second electric unit of described outer twisted wire layer is an aluminium alloy wire.
Described smooth unit comprises stainless steel tube, is provided with some optical fiber in the stainless steel tube.
The utility model has the advantages that: smooth unit of the present utility model does not all closely contact with central reinforce member, first electric unit and second electric unit, and have the heat radiation gap around the light unit, when having guaranteed that the light unit does not stress, guaranteed that also power circuit is when being short-circuited fault, heat of high temperature is difficult to be transmitted to the light unit, prevents that optical fiber is impaired and causes communication disruption.
