Abstract
The utility model discloses a fireproof photoelectric composite cable, comprising an outer protection layer, in which four power transmission cables and one optical cable are arranged. A filling layer is disposed in the gap among the outer protection layer, the power transmission cables and the optical cable. The diameters of the four power transmission cables are different. The diameter of the optical cable is smaller than that of any of the four power transmission cables. The optical cable is adjacent to the power transmission cable having the largest diameter and the power transmission cable having the smallest diameter. The sum of the largest diameter and the second largest diameter of the four power transmission cables is 0.85-1.15 times that of the diameters of the other power transmission cables and the diameter of the optical cable. The filling layer is filled with a glass fiber cord. The outer protection layer is formed by winding multiple layers of glass fiber tapes. A mica tape is wound on the exterior of each of the power transmission cables and the optical cable. The fireproof photoelectric composite cable of the utility model is simple in structure, stable in transmission performance, good in overall tensile strength and bending strength and excellent in fireproof performance.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of fire safe type photoelectric compound cable that can transmit electricity and can transmitting optical signal.
Background technology
At present, along with the fast development of technology, in some field, traditional electric power handling cable has been proposed to new requirement, require light harvesting fiber communication and electric power transfer in one, and intensity has been good, be difficult for bending, advantages of good shielding performance.Existing plastic fiber composite cable is by oversheath, is located in oversheath and the insulating power heart yearn and the fiber unit that twist together form, wherein electric power heart yearn and fiber unit just twist together respectively after each self-forming, in this process, often there is the situation that optical fiber fractures, not only cause scrapping of composite cable, wasted the material of fiber unit simultaneously; Even stranded success simultaneously, also there is larger problem in whole intensity, the problems such as fracture that often have tensile strength deficiency to cause, and also fire resistance is poor.Therefore need a kind of transmission performance of design badly stable, the composite cable that physical structure is good and fire resistance is good.
Utility model content
In order to solve the problem relating in background technology, the utility model provides a kind of fire safe type photoelectric compound cable.
The technical solution of the utility model is: a kind of fire safe type photoelectric compound cable, comprise external protection coating, in described external protection coating, be provided with 4 power transmission cables and 1 optical cable, in the space of described external protection coating and power transmission cable and optical cable, be provided with packed layer, the wire diameter of described 4 power transmission cables is all not identical, the wire diameter of described optical cable is less than in 4 power transmission cables the wire diameter of arbitrary, in described optical cable and 4 power transmission cables, wire diameter is minimum and maximum adjacent, the described optical cable of take distributes and wire diameter increases successively along clockwise direction as 4 power transmission cables of starting point, the 0.85-1.15 that in described 4 power transmission cables, wire diameter wire diameter sum maximum and that take second place is all the other power transmission cables and optical cable wire diameter sum doubly, in described packed layer, be filled with glass cord, described external protection coating is formed by the coiling of compound glass fabric strip, described power transmission cable and optical cable are also all wound with one deck mica tape outward.
As of the present utility model a kind of preferred, in described 4 power transmission cables, wire diameter minimum is 7 core cables, and remaining is 19 core cables.
As of the present utility model a kind of preferably, in described 4 power transmission cables the cable wire diameter of wire diameter maximum be minimum wire diameter cable footpath 1.5-3 doubly.
As of the present utility model a kind of preferred, the 1-1.5 of the wire diameter that in described 4 power transmission cables, the cable wire diameter of wire diameter minimum is optical cable doubly.
As of the present utility model a kind of preferred, described mica tape thickness 0.05-0.1mm.
As of the present utility model a kind of preferred, the glass fiber tape coiling that described external protection coating is 0.2mm by 10 layer thicknesses forms.
In sum, the utlity model has following advantage:
The utility model is simple in structure, and transmission performance is stable, and physical property is good, and whole cable tensile strength and bending strength are all comparatively outstanding, and useful life is longer, and fire protecting performance is comparatively outstanding.
