Abstract
The utility model discloses a high-voltage-resistant photoelectric mixing tension type flat cable, and is characterized in that: the center of the cable is an optical cable, two sides of the optical cable are provided with conductors, the innermost layer of the each conductor is a conducting core formed by intertwisting of galvanized copper wires, a first semiconducting layer, an insulating layer, a second semiconducting layer, a shielding layer and a reinforcing layer are coated outside the conducting core in order, two sides of the outermost conductors are provided with wire ropes, and a sheath is coated outside the optical cable, the conductors and the wire ropes. The high-voltage-resistant photoelectric mixing tension type flat cable of the utility model has the significant advantages that: by adopting a photoelectric mixing structure and simultaneously adding the wire ropes at two sides of the optical cable and the cable, the tension resistance of the cable is raised.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of high pressure resistant photoelectricity mixing tensile type flat cable, belongs to fields such as generating, metallurgy, chemical industry.
Background technology
The photoelectricity composite cable is SUMITOMO CHEMICAL company initiative in 1978, and Application and Development is mainly used in electric power transmission and the communication system extensive use in power communication system at present in the sea floor optoelectronic composite cable.Because light transmission and electrical transmission are two kinds of dissimilar transmission meanss, in the transmission course the phase mutual interference can not take place, in public correspondence is built, the photoelectricity composite cable can solve equipment electricity consumption and signal transmission issues simultaneously, and the characteristic that it has kept the ordinary optic fibre cable can also satisfy the relevant criterion of low voltage power transmission cable.Yet, flatten cable during existing photoelectricity is compound, employed is common cable conductor, and broken easily, poor-performings such as its resistance to wear, weatherability.
The utility model content
The utility model purpose: the purpose of this utility model provides a kind of have superpower resistance to tension, high pressure resistant photoelectricity mixing tensile type flat cable.
Technical scheme: a kind of high pressure resistant photoelectricity mixing tensile type flat cable described in the utility model, the center is optical cable, establish conductor on its both sides, the innermost layer of this conductor is for to close the core of leading that forms by the TC skein silk, outside it, coat first semi-conductive layer, insulating barrier, second semi-conductive layer, screen and back-up coat successively, establish steel wire rope on outermost conductor both sides, outside optical cable, conductor and steel wire rope, coat sheath then.
Wherein, described first semi-conductive layer can be avoided the partial discharge between conductor and the insulator; Second semi-conductive layer can be eliminated the air gap that produces between insulator and the screen, cause it to the deterioration effect of electric field, for example bubble-discharge, insulation breakdown etc.Described insulating barrier is the import silicone rubber insulation layer, makes electrified body and miscellaneous part isolated, guarantees the good electric property that has of product.Described screen is zinc-plated copper wire screen, and by capacitance current, when being short-circuited in system, as the passage of short circuit current, the while can also electric field shielding when normal operation.Described back-up coat is the nonwoven fabrics back-up coat.Described sheath is cold-resistant nitrile rubber sheath, can protect cable not to be subjected to the influence of extraneous machinery, heat, cold, chemistry or moisture.
Beneficial effect: the utility model compared with prior art, its remarkable advantage increases steel wire rope at optical cable and cable both sides simultaneously for adopting the photoelectricity mixed structure, has improved the resistance to tension of cable.
Description of drawings
Fig. 1 is sectional view of the present utility model.
Embodiment
As shown in Figure 1, the center of this cable is optical cable 1, respectively establish two conductors on its both sides, this conductor lead core by multiply tinned copper wire 2 stranded forming, outside leading core, coat first semi-conductive layer 3, import silicone rubber insulation layer 4, second semi-conductive layer 5, zinc-plated copper wire screen 7 and nonwoven fabrics back-up coat 8 successively, establish two steel wires, 6 ropes on outermost conductor both sides, outside optical cable 1, conductor and steel wire rope 6, coat cold-resistant nitrile rubber sheath 9 then.
