Abstract
The utility model discloses a medium-voltage composite cable which comprises a cable core, a heat insulation layer and an outer sheath from the inside out, wherein the cable core comprises an insulation core and a filling strip, which are twisted; a slotting hole which is axially slotted is arranged on the filling strip; and an optic fiber unit is arranged in the slotting hole. In the utility model, the optic fiber unit is arranged in the filling strip with the slotting hole, so that an optic fiber grating unit can be put in or taken out conveniently and practicably, a strengthened sheath structure of the optic fiber grating unit can be omitted simultaneously and the cost is saved while the cable is protected.
Description
Technical field
The utility model relates to field of cables, specifically is a kind of middle Intelligent Composite cable of pressing.
Background technology
The cable that existing transmission and distribution network is used, mostly has only single electric power transfer function, state of insulation that not only can not automatic, real-time, online detection electric wire self, guarantee safe operation effectively, can not transmit various control signals and network signal, be difficult to satisfy modern intelligent grid and realize that electric power, telecommunications, the Internet net the instructions for use of fusion more, but also can not be applied in the high-temperature resistant fire-preventive environment.
Present photoelectricity composite cable, fiber unit mainly is distributed in the gap location of cable core with filling forms, processing mode mainly is to increase the fiber unit that metal or nonmetal reinforcement sheath become band sheath structure outside multifiber, this processing mode is because need be with fiber unit with the metallic conductor cable core stranding of mechanical strength much larger than fiber unit, damage fiber unit easily, if and the thickening reinforced layer can improve the weight and the cost of cable again.
The utility model content
The purpose of this utility model provides a kind of simple in structure, convenient for production, cost is low and combination property is superior middle pressure composite cable.
The technical scheme that realizes the utility model purpose is a kind of middle composite cable of pressing, and comprises from the inside to the outside cable core, thermal insulation layer and outer jacket; Described cable core comprises stranded insulated wire cores and packing; Described packing is provided with axially grooved grooved bore; In the described grooved bore fiber unit is set.
Described insulated wire cores comprises conductor, semiconductive inner shield, insulating barrier, semiconductive external shield and the shielding of metal copper strips from the inside to the outside; Described insulating barrier is high dielectric crosslinked polyethylene.
It is wrapped at the cable core outer surface that described thermal insulation layer employing contains the chromium fiber ceramics.
Described insulated wire cores has three, evenly is provided with; Described packing is fan-shaped, is filled between the adjacent insulated wire cores.
Place the filler that blocks water in the grooved bore of described packing.
The diameter of the grooved bore of described packing is greater than the diameter of fiber unit.
Adopted technique scheme, the utlity model has following beneficial effect: (1) the utility model is arranged on tape spool in the packing of grooved bore with fiber unit, passable is easy to operate feasible, can save simultaneously the reinforcement sheath structure of fiber grating unit, both facility had also been saved cost.
Also the filler that blocks water can be added when (2) adding fiber unit in the fluting circular hole of packing of the present utility model, the fiber unit requirement that radially, vertically blocks water can be reached like this.
(3) diameter of the circular hole of packing of the present utility model helps surplus long optical fibers unit and enters in the filling cylindrical void greater than the fiber grating element diameter.
(4) thermal insulation layer of the present utility model adopts the soft junction structure, the pottery that contains the chromium fiber is fabulous exotic material, because its proportion is significantly less than other refractory material, thereby accumulation of heat is very little, effect of heat insulation is obvious, has good bending property again, can make insulating material, can make high-temperature refractory again, the serviceability temperature of cable of the present utility model is brought up to more than 1500 ℃, largely improve the bendability of existing fire-resisting cable simultaneously, and has higher fire insulation performance and intensity, still can fire-proof and thermal-insulation at big fire barbecue environment, reach at water and drench, the safety that still can keep cable insulation under the vibration environment reaches long period continuation power supply.
(5) the utility model processing technology is simple,, fiber unit is directly inserted the packing that forms the band fiber unit in the grooved bore of packing; The same with common power cable during the composite cable stranding, process equipment and moulds of industrial equipment do not need to improve, and can reduce the processing charges of cable.
(6) fiber unit of composite cable of the present utility model can be used for the transmission network signal, automatically, real time on-line monitoring cable insulation operation conditions itself, effectively guaranteed convenience, fail safe and reliability that cable moves.
