Novel environment friendly photoelectricity composite communication cable

Technical field

This utility model relates to communication technical field, particularly relates to a kind of novel environment friendly photoelectricity composite communication cable.

Background technology

At present, flourish along with communications industry 4G network, in communication network service, telephone service is in steadily Growth trend, and data service is exponentially increased situation, and the multimedia such as voice, data and image is required to Transmission, so needing bigger network capacity and broader wide bandwidth.Novel environment friendly photoelectricity composite communication cable, It integrates optical fiber, communication cable, not only can solve equipment electricity consumption, signal transmission, but also can solve width With incoming light signal reception, be a kind of novel access way.

Utility model content

The purpose of this utility model is to provide a kind of novel environment friendly photoelectricity composite communication cable, overcomes existing skill There is the problems such as big, purchase cost height that take up room in art, under Environmental Safety premise, be provided that light is believed simultaneously Number transmission and supply of electric power.

To achieve these goals, this utility model have employed following technical scheme: a kind of novel environment friendly light Reply hop communication cable by cable, including being placed in the optical cable at composite rope center, many power lines and be set in turn in power supply Lapping layer, sealing coat, chain armor and external sheath layer outside line；

Described power line includes conductor and the synthetic mica tape flame retardant coating being coated on successively outside conductor, insulating barrier；

Gap between described power line and lapping layer is filled by combustion-proof glass fiber；

Described sealing coat uses low smoke halogen-free flame-retardant polyolefin；

Described chain armor uses the chain armouring of aluminum alloy strip.

Wherein, described insulating barrier and sealing coat all use low smoke halogen-free flame-retardant polyolefin.

Wherein, described conductor is soft circular copper wire.

Wherein, described external sheath layer uses that environmental-protection low-smoke halogen-free is flame-retardant polyolefin sheathed extrudes.

Wherein, described lapping layer uses LSOH anti-flaming band wrapped.

Wherein, described optical cable includes optical fiber, fine cream and Loose tube, for single or multicore.

The beneficial effects of the utility model are: after using above-mentioned cable, and optical cable is placed in composite rope center, and The common stranded molding of power line, gap is filled pyroceram silk fiber rope, is strengthened fire-resistant, high temperature resistant Performance, transmits while so can be achieved with optical signal transmission and supply of electric power.

External diameter is little, lightweight, takes up room little, has superior bending property and good resistance to pressure measurement performance, It is easy to lay and transport；Cost-effective, operating expenses is low, i.e. solves equipment electrical problem in networking, Optical fiber can be used as reserved again, it is to avoid secondary wiring；Multiple transmission technology, same equipment are provided simultaneously Adaptability high, extensibility strong, product is widely applicable；The bandwidth providing huge accesses.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment technical scheme, institute in embodiment being described below The accompanying drawing used is needed to be briefly described, it should be apparent that, the accompanying drawing in describing below is only this practicality Novel in order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below by p- In embodiment or description of the prior art, the required accompanying drawing used is briefly described, skill common for this area From the point of view of art personnel, on the premise of not paying creative work, it is also possible to obtain other according to these accompanying drawings Accompanying drawing.

Fig. 1 is cross-sectional structure schematic diagram of the present utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people The every other embodiment that member is obtained under not making creative work premise, broadly falls into this utility model The scope of protection.

Novel environment friendly photoelectricity composite communication cable as shown in Figure 1, including being placed in the optical cable 9 at composite rope center, Many power lines and the lapping layer 5, sealing coat 6, the chain armor 7 that are set in turn in outside power line and protect outward Jacket layer 8；Described power line include conductor 1 and the synthetic mica tape flame retardant coating 2 being coated on successively outside conductor 1, Insulating barrier 3；Gap between described power line and lapping layer 5 is filled by combustion-proof glass fiber 4；Institute State sealing coat 6 and use low smoke halogen-free flame-retardant polyolefin；Described conductor 1 is soft circular copper wire.

Using synthetic mica tape to carry out wrapped outside conductor, refractory temperature can reach 700～800 DEG C；This cable can be Stand the flame-retardant test of 90min at 750 DEG C～800 DEG C, be applicable to the place that fire resistant requirements is higher.

Described insulating barrier 3 uses low-smoke halogen-free polyolefin to insulate, due to low smoke halogen-free flame-retardant polyolefin oxygen index (OI) relatively Height, electrical property is good and has the characteristics such as low cigarette, Halogen；Its temperature resistant grade and mechanical performance also ratio is poly-simultaneously Vinyl chloride is good, so insulating barrier also has premium properties.

Described chain armor 7 uses the chain armouring of aluminum alloy strip, just can reach certain shield effectiveness, with Time there is the protective effect to internal cable core, also can need not use corrugated tube during laying cable, Thus also reduce installation cost.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all Within protection domain of the present utility model should be included in.
