Abstract
The utility model discloses a novel dry optical-unit type optical-fiber composite cable. The cable core of the optical-fiber composite cable is internally provided with a loose tube, the loose tube is internally provided with optical fibers and a dry water-stopping object, the loose tube is wrapped with an aluminum-plastic composite tape, the aluminum-plastic composite tape and an electrical lead form the cable core, and a steel-tape armoring layer is arranged between an inner sheath and an outer sheath outside the cable core. Because the optical fibers are arranged in the aluminum-plastic composite tape, the aluminum-plastic composite tape prevents the electromagnetic interference from external electrical leads to the optical fibers; the dry water-stopping object in the loose tube can prevent the intrusion of moisture; and the steel-tape armoring layer between the inner sheath and the outer sheath enhances the strength of the optical-fiber composite cable.
Description
Technical field
The utility model relates to field of cables, particularly a kind of composite cable that has optical fiber communication function and electric power transfer function concurrently.
Background technology
At present, general central beam tube type optical cable has only communication function, can not transmit electric power simultaneously to communication equipment and power equipment, can only select other power cable laying, repeats wiring, causes waste.Traditional central beam tube type cable adopts the filled type ointment that blocks water, and the restriction of laying drop is installed, and novel dry type central beam tube type cable adopts no ointment stop water, and the restriction of laying drop can be installed.
The utility model content
In order to overcome the deficiency that existing central beam tube type optical cable can not carry out optical fiber communication and electric power transfer simultaneously; The utility model provides a kind of novel dry type light unit optical fiber composite cable, and this novel dry type light unit optical fiber composite cable can carry out optical fiber communication and electric power transfer simultaneously.
The utility model solves the technical scheme that its technical problem adopted: be provided with optical fiber in the loose sleeve pipe of novel dry type light unit optical fiber composite cable; Be provided with the dry type water-blocking material between pine sleeve pipe and the optical fiber; Pine sleeve pipe outerwrap aluminium-plastic tape, aluminium-plastic tape and electrical lead are formed cable core, and cable core is wrapped in the inner sheath; Inner sheath is wrapped in the steel-tape armouring layer, and the steel-tape armouring layer is outward an oversheath.
The utility model beneficial effect be because the optical fiber in the pine cover is positioned at the dry type water-blocking material, no ointment stop water, the saving optical fiber set-up time, cable is not limited by drop; Optical fiber is positioned at plastic-aluminum combined pipe racks, and aluminium-plastic tape has stoped the electromagnetic interference of extraneous electrical lead to optical fiber; Steel-tape armouring layer between inner sheath and the oversheath has been strengthened the intensity of this Optical Fiber Composite cable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. optical fiber, 2. dry type water-blocking material, 3. loose sleeve pipe, 4. aluminium-plastic tape, 5. electrical lead, 6. inner sheath, 7. steel-tape armouring layer, 8. oversheath.
Embodiment
In Fig. 1, be provided with optical fiber 1 in the loose sleeve pipe 3 of novel dry type light unit optical fiber composite cable, be provided with dry type water-blocking material 2 between loose sleeve pipe 3 and the optical fiber 1; Dry type water-blocking material 2 is a water blocking yarn in the present embodiment; Pine sleeve pipe 3 outerwrap aluminium-plastic tapes 4, aluminium-plastic tape 4 is formed cable core with electrical lead 5, and cable core is wrapped in the inner sheath 6; Inner sheath 6 is wrapped in the steel-tape armouring layer 7, is oversheath 8 outside the steel-tape armouring layer 7.
