Abstract
The invention discloses a self-supporting aerial insulated service drop cable which consists of an insulating layer of a first cable body, a conductive wire core of the first cable body, a connecting body, the insulating layer of a second cable body and the conductive wire core of the second cable body, the conductive wire core of the first cable body and the conductive wire core of the second cable body have the same circular cross section, the insulating layer of the first cable body, the connecting body and the insulating layer of the second cable body constitute an integrated structure, and a continuous convex ridge-shaped polarity marking line is arranged on the outer surface of the insulating layer of the first cable body. The self-supporting aerial insulated service drop cable has stable operation, safety and reliability by adopting the structure, the self-supporting aerial insulated service drop cable is less affected by natural factors of wind force and the like, the service life is prolonged; the appearance is beautiful, the support and the installation are convenient; the bending performance is good and can be applicable to spaces with higher requirements on the bending performance, the using spaces thereof are expanded and the manufacturing cost is reduced.
Description
Technical field
The present invention relates to electric wire, relate in particular to self-supporting type aerial insulated user's cable.
Background technology
Along with the development of town and country construction and deeply, the urban and rural power grids development is healed and is become ripe, the aerial insulated user cable is used widely, at present the aerial insulated user cable has two single-core cables parallel mode and the stranded mode of twin-core, and two parallel overhead insulating electricity of single-core cable connect the family cable and exist following deficiency: manufacturing cost is higher; In use, because natural causes such as wind-force can cause the friction that runs foul of each other between the cable, cause cable fault, useful life is shorter.And the stranded aerial insulated cable of twin-core can occur: 1) because needs two molds, one mold has the polarity tag line, the nonpolarity tag line of an other mold, in the production process, need die change, cause the waste of insulating material during die change easily, and the cost chronic, manufacturing cost is higher; 2) collision that easily takes place between core because of natural causes such as wind-force is pushed, and influences useful life.
Summary of the invention
Technical problem to be solved by this invention is: a kind of self-supporting type aerial insulated user's cable is provided, and this self-supporting type aerial insulated user's cable has strengthened the performance of natural causes such as wind resistance power influence, has prolonged useful life, has reduced manufacturing cost.
Solve this technical problem, technical scheme of the present invention is: a kind of self-supporting type aerial insulated user's cable, it is by the first cable body insulating barrier, the first cable body conductor wire core, connector, the second cable body insulating barrier and the second cable body conductor wire core are formed, the described first cable body conductor wire core has identical circular cross section with the second cable body conductor wire core, the described first cable body insulating barrier, the connector and the second cable body insulating barrier are for forming the structure of one, and the outer surface of the described first cable body insulating barrier is provided with polarity mark's line of continuous form of ridges.
The lateral dimension e of described connector is 1.2～2 millimeters, and the thickness of connector is 0.7～1 millimeter.
The lateral dimension e of described connector is 1.5 millimeters, and the thickness of connector is 0.8 millimeter.
A kind of self-supporting type aerial insulated user's cable of the present invention adopts such structure, has following beneficial effect: 1) have good self-bearing capacity, its cross section can be got below 10 square millimeters; 2) stable, safe and reliable, it is less influenced by natural causes such as wind-force, has prolonged useful life; 3) good looking appearance is convenient to set up installation; 4) good bending property can be suitable for the place that bending property is had relatively high expectations, and has enlarged its field of employment; 5) reduced manufacturing cost.
