Abstract
The utility model discloses a photoelectric composite cable which comprises an outer protective layer. Four power transmission cables and one optical cable are arranged in the outer protective layer, and filling layer is filled in the gaps among the power transmission cables and the optical cable. The four power transmission cables are different in wire diameter, and the wire diameter of the optical cable is smaller than any of the power transmission cable. The optical cable is in the center of the four power transmission cables, and axis of the optical cable is superposed with the axis of the outer protective layer. The sum of the wire diameter of the largest power transmission cable and that of the second largest power transmission cable is 0.85-1.15 times of the total wire diameters of the other cables including power transmission cables and the optical cable. The photoelectric composite cable is simple in structure, stable in transmission performance, excellent in physical properties, integral tensile strength and bending strength, and long in service lifetime.

The utility model content
In order to solve the problem related in background technology, the utility model provides a kind of photoelectric compound cable.
The technical solution of the utility model is: a kind of photoelectric compound cable, comprise external protection coating, be provided with 4 power transmission cables and 1 optical cable in described external protection coating, be provided with packed layer in the space of described external protection coating and power transmission cable and optical cable, 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, described optical cable is positioned at described 4 power transmission cable centre positions and described optical cable axis and described external protection coating axis and coincides, the 0.85-1.15 that in described 4 power transmission cables, wire diameter is maximum and wire diameter sum that take second place is all the other power transmission cables and optical cable wire diameter sum doubly.
As of the present utility model a kind of preferred, described packed layer comprises the center-filled layer that described optical cable is wrapped up and is arranged on described center-filled layer four radially packed layers, described four radially packed layer, center-filled layer and external protection coating surround four installation cavitys, described 4 power transmission cables are arranged in described four installation cavitys, are provided with limit section packed layer in described installation cavity.
As of the present utility model a kind of preferred, in described 4 power transmission cables, the wire diameter minimum is 7 core cables, and remaining is 19 core cables, and the line of centres of described 4 power transmission cables is square.
As of the present utility model a kind of preferred, described external protection coating is formed by the multi-layer nonwoven fabrics coiling.
As of the present utility model a kind of preferred, the 1.5-3 that in described 4 power transmission cables, the cable wire diameter of wire diameter maximum is minimum wire diameter cable footpath 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.
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.
