Abstract
The utility model discloses a cross-linked polyethylene insulated armored cable with a function of communication, and overcomes the problems of large spans of power transmission cables in special occasions and unstable power transmission of a common wire in the prior art. The cable provided by the utility model comprises an outer sheath, a wrapping layer, a first group of stranded conductors, a communication wires, an insulating layer, and a second group of wires. The interior of the outer sheath is provided with the wrapping layer in a pasted manner. The wrapping layer wraps the first group of stranded conductors and the communication wires. The insulation wraps the second group of wires. The first group of stranded conductors and the communication wires equipped with an independent insulation layer are respectively distributed at the periphery of the insulating layer. The number of strands of the first group of stranded conductors is greater than that of the second group of wires. The number of strands of the communication wires is an even number which is greater than or equal to 2. The number of strands of the first group of stranded conductors of the cable is obviously more, thereby achieving the cable-armouring effect, and improving the load capability of the cable. The cable provided by the utility model is equipped with a plurality of pairs of communication wires, has the functions of telephone communication and remote control, thereby simplifying the circuit wiring.
Description
Technical field
This utility model relates to a kind of power cable, particularly relates to a kind of crosslinked polyetylene insulated armoured cable with communication function.
Background technology
Power cable is in order to transmit and to distribute the cable product of high-power power in the basic routing line of electric power system.At present, along with the development of telecommunications, it is also more and more welcome that cable has the feature of communication function.In reality transmission of electricity occasion, some user can be distant apart from distribution center, some mountain area is rough and uneven in surface causes electric pole skewness, can cause the span of local wire larger, use common cable can cause cable in the sagging prolongation of self gravitation and the adstante febre that is heated, virtually increased the resistance of wire, the degree of heat and then continuation increase, and use for a long time easily accidents caused under bad working environments.Therefore, just need to use armoured cable.
Utility model content
It is large that the utility model has overcome in prior art under special occasions power transmission cable span, and the plain conductor unsettled problem of transmitting electricity provides a kind of crosslinked polyetylene insulated armoured cable with communication function of simple in structure, stable performance.
Technical solution of the present utility model is, provide a kind of crosslinked polyetylene insulated armoured cable with communication function with following structure: contain oversheath, integument, first group of stranded conductor, communication conductor, insulating barrier and second group of wire, in oversheath, post integument, integument wraps up first group of stranded conductor and communication conductor, insulating barrier wraps up second group of wire, first group of described stranded conductor is distributed in around insulating barrier with the communication conductor with independent insulating barrier, the number of share of stock of first group of stranded conductor is greater than the number of share of stock of second group of wire, the number of share of stock of communication conductor is to be more than or equal to 2 even number.
Second group of wire is sub-thread or stranded conductor, and its material is silver, copper, aluminium or iron.First group of stranded conductor annular spread around and with second group of wire coaxially distributes in insulating barrier, and its material is silver, copper, aluminium or iron.The insulating barrier color of communication conductor is different, and the material of communication conductor is silver, copper, aluminium or iron, and the insulating barrier of communication conductor is polyethylene.
Between oversheath and integument, have a tough and tensile flexible tearing line, its material is nylon, and the material of oversheath is polyethylene, and the material of integument is polyester film.The group number of wire is to be more than or equal to 2 natural number, and the group number of insulating barrier is to be more than or equal to 1 natural number.The material of insulating barrier is crosslinked polyethylene.
Compared with prior art, the crosslinked polyetylene insulated armoured cable that the utlity model has communication function has the following advantages: the number of share of stock of first group of stranded conductor is obviously greater than the number of share of stock of second group of wire, can play armature of cable effect, and can increase the ability of cable load.There is multipair communication conductor simultaneously, can hold concurrently telephone communication and remote control function, thus reach simplification wiring.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utlity model has the crosslinked polyetylene insulated armoured cable cross section of communication function.
Embodiment
In accompanying drawing explanation, label 1 is oversheath, the 2nd, and integument, 3 is first group of stranded conductor, the 4th, insulating barrier, 5 is second group of wire, the 6th, tearing line, the 7th, the insulating barrier of communication conductor, the 8th, communication conductor.
Below in conjunction with the drawings and specific embodiments, to the utlity model has the crosslinked polyetylene insulated armoured cable cross section of communication function, be described further: as shown in the figure, the utility model contains oversheath, integument, first group of stranded conductor, communication conductor, insulating barrier, second group of wire, first group of described stranded conductor is distributed in around insulating barrier with the communication conductor with independent insulating barrier, the number of share of stock of first group of stranded conductor is greater than the number of share of stock of second group of wire, and the number of share of stock of communication conductor is to be more than or equal to 2 even number.
Second group of wire is sub-thread or stranded conductor, and its material is silver, copper, aluminium or iron.First group of stranded conductor annular spread around and with second group of wire coaxially distributes in insulating barrier, and its material is silver, copper, aluminium or iron.The insulating barrier color of communication conductor is different, and the material of communication conductor is silver, copper, aluminium or iron, and the insulating barrier of communication conductor is polyethylene.
Between oversheath and integument, have a tough and tensile flexible tearing line, its material is nylon, and the material of oversheath is polyethylene, and the material of integument is polyester film.The group number of wire is to be more than or equal to 2 natural number, and the group number of insulating barrier is to be more than or equal to 1 natural number.The material of insulating barrier is crosslinked polyethylene.
This product can be maked somebody a mere figurehead wiring, cable testing bridge wiring and the interior wiring of cable shaft etc.
