Description
Technical field
The present invention relates to electric wire field, be specifically related to a kind of Great span reinforced aerial insulated cable。
Background technology
Cable refers to the material for electric power, communication and associated transport purposes, at present, development along with society, the demand of cable rises steadily, and people are also more and more higher to the requirement of cable, particularly in the environment of aerial cable, when cable is subject to external stress effect, its internal wire is susceptible to displacement, causes that cable local temperature is too high, affects the communication efficiency of cable；Connecting typically by dowel between the cable of cable, when dowel is damaged, cable can be separated from one another, it is easy to the sheath of cable is caused damage, affects the performance such as wear-resisting, high temperature resistant of cable；Existing cable radiating effect is poor, in cable work process, it is impossible to is effectively dissipated by the heat that conductor produces, causes that conductor temperature is too high, cause its current-carrying capacity to reduce；
Aerial cable is the important kind of one in information transmission, is mainly used as radio and launches or receive the feeder of equipment and various communication, the machine intraconnections of electronic equipment or be connected with each other line。Aerial cable is made up of inner conductor layer, insulating barrier, outer conductor layer and restrictive coating, inner conductor layer and the usual cross section of outer conductor layer are only small, from carrying poor performance, especially when cable uses under not buried operating mode, owing to load-carrying properties are poor, cable own wt can make cable conductor break, and is also easily damaging tiny cable conductor when construction simultaneously。
Prior art adopts bracing frame that cable is supported; aerial cable is protected by increasing the form of bracing frame; there is certain effect; but add laid down cost and time; in addition the load-carrying properties of cable own are poor, unavoidably can because operation causes the problem that the core of cable damages accidentally in work progress；It addition, major part cable is all too high by temperature, causes spontaneous combustion, cause very big loss。
Summary of the invention
In order to overcome the deficiencies in the prior art, it is provided that a kind of have very strong carrying and compressive property certainly, moistureproof and good airproof performance, little, the good reinforced aerial cable of insulation effect of decaying。
For achieving the above object, the invention discloses a kind of Great span reinforced aerial insulated cable, including the first conductor layer being arranged on cable bosom, being externally provided with the second conductor layer at the first conductor layer, extruding thickness outside the second conductor layer successively is that the insulating barrier of 2-4mm, Jacket thickness are the silver-plated annealing copper strips armor of 3-6mm and extrude the plastic-aluminum armouring pe sheath layer that thickness is 8-10mm；The first described conductor layer is formed by galvanized strand wires strengthening core at its center and some tinned copper conductors being centered around outside galvanized strand wires strengthening core for the center of circle with galvanized strand wires strengthening core are stranded；Second conductor layer is formed with the symmetrical tin plated steel wire carrying core of cable center and some tin plating nickel conductor combination by a pair。
Improve further, between the first described conductor layer and the second conductor layer, be provided with the flexible radiating tube of multiple annular distribution。
Improve further, in described flexible radiating tube, be provided with coolant。
Improving further, described tin plated steel wire carries Xin You center zinc-coated wire and is extruded in the polyethylene protective layer that the thickness outside zinc-coated wire is 3-6mm。
Compared with prior art, the beneficial effects of the present invention is:
1, the present invention has very strong reinforcing property, and the first conductor layer central core of cable has a galvanized strand wires strengthening core, and the stress point of conductor concentrates on the strengthening core of center, and cable, in folding and unfolding winding process, protects inner wire, and is not easily broken；
2, the present invention has and very strong is provided with a pair carrying core in load-carrying properties, the second conductor layer of cable, and the stress point of the second conductor concentrates on this pair carrying core, and cable, in folding and unfolding winding process, protects outer conductor, and is not easily broken；
3, the present invention is provided with radiating tube and by temperature transfer to its internal coolant, to reduce the temperature in cable use procedure, it is ensured that cable will not be answered temperature too high and be caused the reduction of its current-carrying capacity；
4, conductor of the present invention adopts tinned copper conductor and tin plating nickel conductor so that cable has lightweight, acid and alkali-resistance, and shield effectiveness is good, the advantage that oxygen-proof property is strong, and to allow working environment maximum temperature be 85 DEG C, and the minimum temperature of mounting and installation is-10 DEG C；Can stand exchange 50HZ, 3.5Kv/5min voltage and not breakdown。
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention。
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, it is further elucidated with the present invention, it should be understood that these embodiments are merely to illustrate the present invention rather than restriction the scope of the present invention, after having read the present invention, the amendment of the various equivalent form of values of the present invention is all fallen within the application claims limited range by those skilled in the art。
As shown in Figure 1, the present invention provides a kind of Great span reinforced aerial insulated cable, including the first conductor layer 1 being arranged on cable bosom, it is externally provided with the second conductor layer 2 at the first conductor layer, outside the second conductor layer, extrudes insulating barrier 3 that thickness is 2-4mm successively, Jacket thickness is the silver-plated annealing copper strips armor 4 of 3-6mm and extrudes the plastic-aluminum armouring pe sheath layer 5 that thickness is 8-10mm；The first described conductor layer 1 is formed by galvanized strand wires strengthening core 6 at its center and the some tinned copper conductors 7 that are centered around outside galvanized strand wires strengthening core for the center of circle with galvanized strand wires strengthening core 6 are stranded；Second conductor layer 2 is combined with the symmetrical tin plated steel wire carrying core 8 of cable center and some tin plating nickel conductors 9 by a pair, adopt tinned copper conductor and tin plating nickel conductor, cable is had lightweight, acid and alkali-resistance, shield effectiveness is good, the advantage that oxygen-proof property is strong, and to allow working environment maximum temperature be 85 DEG C, the minimum temperature of mounting and installation is-10 DEG C；Can stand exchange 50HZ, 3.5Kv/5min voltage and not breakdown。
