Abstract
The utility model discloses a composite overhead ground wire including an optical unit. A plurality of first electric units are twisted outside the optical unit. Second optical units are formed outside the first electric units. The first electric unit and the second electric unit are not in close contact. Heat dissipating gaps exist between the optical unit and the first electric units. A sheath is sleeved outside the second electric units. The composite overhead ground wire provided by the utility model has advantages that the heat dissipation effect is good since the first electric unit and the second electric unit are not in close contact and the heat dissipating gaps exist between the optical unit and the first electric units, so that high-temperature heat is difficult to transfer to the optical unit when short troubles occur in a power circuit. Therefore, optical fibers are prevented from damaging and communication interruption is avoided.
Description
Technical field
The utility model relates to a kind of composite overhead ground wire.
Background technology
Mainly contain two kinds of Optical Fiber composite overhead Ground Wire on the market, center type Optical Fiber composite overhead Ground Wire and layer-twisted type Optical Fiber composite overhead Ground Wire, power department is for improving the security reliability of optical cable transmission line, preferred electric power special optical cable is laid along the high-voltage line power line, tradition layer-twisted type Optical Fiber composite overhead Ground Wire is when power circuit is short-circuited fault, heat of high temperature heat radiation is relatively poor, and optical fiber is easily impaired and cause communication disruption.Therefore, need provide a kind of new technical scheme to solve the problems referred to above.
The utility model content
The purpose of this utility model provides a kind of composite overhead ground wire of good heat dissipation effect.
The technical solution adopted in the utility model is:
A kind of composite overhead ground wire, comprise the light unit, stranded outside the described smooth unit have a plurality of first electric units, described first electric unit is formed with second electric unit outward, not closely contact between described first electric unit and second electric unit, exist the heat radiation gap between described smooth unit and first electric unit, described second electric unit is with sheath outward.
Described first electric unit is aluminium-clad steel wire.
Described second electric unit is aluminium alloy wire.
Described smooth unit comprises stainless steel tube and multifiber, and described multifiber is located in the stainless steel tube.
Described sheath is the anti-electric-mark sheath.
The beneficial effects of the utility model: not closely contact between first electric unit and second electric unit, exist the heat radiation gap between light unit and first electric unit, good heat dissipation effect, when power circuit is short-circuited fault, heat of high temperature is difficult to be transmitted in the light unit, avoids optical fiber impaired and cause communication disruption.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, stainless steel tube, 2, optical fiber, 3, aluminium-clad steel wire, 4, aluminium alloy wire, 5, the heat radiation gap, 6, sheath.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of composite overhead ground wire of the present utility model, comprise the light unit, the light unit comprises stainless steel tube 1 and multifiber 2, multifiber 2 is located in the stainless steel tube 1, stranded outside the light unit have a plurality of first electric units, first electric unit is aluminium-clad steel wire 3, first electric unit is formed with second electric unit outward, second electric unit is not closely contact between aluminium alloy wire 4, the first electric units and second electric unit, exists heat radiation gap 5 between light unit and first electric unit, second electric unit is with sheath 6 outward, and sheath 6 is the anti-electric-mark sheath.
Not closely contact between first electric unit and second electric unit, exist the heat radiation gap between light unit and first electric unit, good heat dissipation effect is when power circuit is short-circuited fault, heat of high temperature is difficult to be transmitted in the light unit, avoids optical fiber 2 impaired and cause communication disruption.
