Abstract
The present utility model discloses a double layer light unit overhead ground wire. The ground wire comprises a light unit, the light unit comprises an aluminum pipe, a stainless steel pipe, a plurality of optical fibers and a middle reinforcing core, the optical fibers are uniformly arranged outside the middle reinforcing core, the optical fibers and the middle reinforcing core are arranged inside the stainless steel pipe, the stainless steel pipe is arranged inside the aluminum pipe, a metal stranding layer is arranged outside the aluminum pipe, a buffer member is arranged outside the metal stranding layer, and a sheath is arranged outside the buffer member. A contacting part between the light unit and the metal stranding layer is made of aluminum, electric corrosion can be avoided, a shielding wire is arranged between the buffer member and the sheath, interferences of electric waves are small, and the signal transmission effect is good.
Description
Technical field
The utility model relates to a kind of overhead ground wire, relates in particular to a kind of double-deck light unit overhead ground wire.
Background technology
Mainly contain two kinds of Optical Fiber composite overhead Ground Wire on market, center type Optical Fiber composite overhead Ground Wire and stranded optical fiber composite overhead ground wire, tradition layer-twisted type Optical Fiber composite overhead Ground Wire all is placed on by optical fiber and forms the light unit in stainless steel tube, because existing smooth unit is all as sleeve pipe by stainless steel tube, galvano-cautery easily occurs between itself and aluminum metal lines, and in signals transmission, easily be subjected to wave interference.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
The utility model content
The purpose of this utility model be to provide a kind of antiseptic property good, in disturbing little double-deck light unit overhead ground wire.
The technical solution adopted in the utility model is:
A kind of double-deck light unit overhead ground wire, comprise the light unit, described smooth unit comprises aluminum pipe, stainless steel tube, multifiber and middle strengthening core, multifiber is distributed in outside middle strengthening core, multifiber and middle strengthening core are located in stainless steel tube, and described stainless steel tube is arranged in aluminum pipe, and described aluminum pipe is provided with the metal stranded layer outward, described metal stranded layer is provided with bolster outward, and described bolster is provided with sheath outward.
Described metal stranded layer is aluminium alloy wire.
Be provided with shielding conductor between described bolster and sheath.
Described bolster is plastic foam.
Described sheath is pe sheath.
The beneficial effects of the utility model: between light unit and metal stranded layer, the contact portion material is aluminium, galvano-cautery can not occur, and is provided with shielding conductor between bolster and sheath, is subjected to wave interference little, and signal transmission effect is good.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, aluminum pipe, 2, stainless steel tube, 3, optical fiber, 4, middle strengthening core, 5, aluminium alloy wire, 6, sheath, 7, plastic foam, 8, shielding conductor.
Embodiment
