Abstract

The utility model relates to an armoured integrated electric power communicating optical cable which is characterized in that an inner core is composed of four core optical fibers, three power supply lines and filling materials. In the utility model, the inner core is respectively composed of and is covered and wound by a covering belt layer, an inner sheath and an outer sheath. The utility model can simultaneously transport light signals and alternate current 220V strong electricity in optic cables, has good waterproof property at the same time, can enhance the stability and reliability of systems and can reduce cost.

Description

Armouring combined power communications optical cable

Technical field: the utility model relates to the optical communication technique field, belongs to a kind of optical cable of information transmission specifically.

Background technology: present harbour, harbour and Container Yard, generally adopt wireless data to pass reportedly feed technique, and modern harbour is the container wharf, container weighs 40 tons, general communications optical cable crushes easily, and optical cable inside only comprises optical fiber or doublely is with some signal wires, this type of signal can only transmit weak electric signals such as phone, can not transmit long-range high voltage and big electric current, so can not satisfy the requirement of high-quality power supply and uninterrupted power supply, therefore the current significant problem that must solve.

Summary of the invention: the purpose of this utility model provide a kind of at the harbour, place such as harbour and Container Yard, with the signal of the radio communication base station in a distant place by Optical Fiber Transmission to information center, this radio communication base station can satisfy the armouring combined power communications optical cable of 24 hours different cut-off electricity simultaneously.

For finishing the technical scheme that above-mentioned purpose is taked: the steel wire that the utility model integral body is provided with by four groups of stranded four-core optical fiber that form of OFCC, three power leads, center, some are moulded the inner core that a filler and factice for filling are formed, the above-mentioned wrapped belting layer in the inner core outside, above-mentioned band is respectively around PE inner sheath, steel band, PE oversheath, the steel wire that above-mentioned optical cable center is provided with is a steel wire with plastic plated, and above-mentioned belting layer is the steel-tape armouring layer.

Performance of the present utility model satisfies request for utilization fully, is implemented in while transmitting optical signal and alternating current 220V forceful electric power in the optical cable, has premium properties such as waterproof simultaneously, and the stability of raising equipment and system and reliability reduce construction cost.

Description of drawings:

Fig. 1 is the utility model structural drawing.

Specific implementation method: of the present utility modelly 1 be described in detail in conjunction with the accompanying drawings.Total is provided with by the stranded four-core optical fiber that forms of four groups of OFCC 6, three power leads 8, centers that steel wire 7, some are moulded a filler 9 and factice for filling 5 is formed the optical cable inner core, the steel wire 7 that above-mentioned center is provided with is a steel wire with plastic plated, guarantee the line of electric force insulation interior with optical cable, three power leads 8 are three-phase power line, the factice for filling of inner core setting has favorable waterproof property, and line of electric force 1 is three sectional area 2.5mm simultaneously ²The multiply copper cash.The wrapped belting layer 4 in the inner core outside that meter is stated, wherein belting layer 4 is distinguished line PE inner sheaths 3, steel band 2, PE oversheath, described belting layer 4 is the vertical Baogang of embossing band armouring, oversheath 1 is made up of tygon, therefore whole optical cable has environmental suitability and good mechanical properties such as good tension, resistance to compression, allows serviceability temperature at-20～+ 60 ℃.
