Abstract

The utility model relates to a figure eight-shaped optic/electric composite flame resistant cable which comprises a power cable and an optical fiber cable; the cable core of the power cable is provided with a lead wire and a filling rope with insulating layers wrapped outside conductors; each conductor consists of a plurality of strands of tinned copper wires; a heat isolating layer, a copper wire woven shielding layer and an outer protective cover are subsequently wrapped outside the cable core of the power cable; the cable core of the optical fiber cable is provided with an optical fiber with a sleeve wrapped outside and a tensile reinforcer; the outer protective cover is wrapped outside the cable core; the outer protective cover of the power cable and the outer protective cover of the optical fiber cable are connected into a figure eight shape; a connecting sling is arranged between the two outer protective covers. The figure eight-shaped optic/electric composite flame resistant cable is applicable to the occasions which need power transmission and light signal transmission at the same time, can realize the purpose only by laying a cable without secondary laying, so as to reduce the laying cost and reduce the construction intensity; and the wire displacement is neat, and the searching is convenient in case of faults.

Description

8 shaped photoelectric composite flame-retardant cables

Technical field

The utility model relates to a kind of cable, especially has the photoelectricity composite cable of electric power transfer function and optical fiber communication function concurrently.

Background technology

Existing power cable and communications optical cable all are independent manufacturings, laying installation respectively during use, for the occasion that needs electric power transfer and optical signal transmission simultaneously just necessary power cable laying and optical cable respectively, cause cable, optical cable secondary to lay, laid down cost improves, construction intensity increases, and winding displacement is mixed and disorderly, breaks down to search difficulty.

Summary of the invention

In order to overcome the deficiency that existing power cable and optical cable are made separately, laid respectively, the utility model provides a kind of 8 shaped photoelectric composite flame-retardant cables, power cable and optical cable are combined, the occasion that needs electric power transfer and optical signal transmission is at the same time laid a cable and just can be achieved the goal.

A kind of 8 shaped photoelectric composite flame-retardant cables that the utility model provides comprise power cable and optical cable, be provided with lead in the cable core of power cable at conductor outsourcing insulating layer coating, gasket for packing, the conductor of power cable is made of the multiply tinned copper wire, outside the cable core of power cable, coat thermal insulation layer successively, the copper wire woven shield, oversheath, be provided with the optical fiber of outer canning tube in the cable core of optical cable, the tension reinforcement, outside the cable core of optical cable, coat oversheath, the oversheath of power cable and the oversheath of optical cable fuse and are 8 fonts, are provided with the connection suspender belt between two oversheaths.

The beneficial effects of the utility model are: need the occasion of electric power transfer and optical signal transmission at the same time, only need once lay the utility model and just can achieve the goal, do not need secondary to lay, reduce laid down cost, reduce construction intensity, and winding displacement is neat, searches conveniently in case break down.
