Abstract

The utility model discloses an insulating steel strip armoring optic fibre composite low -voltage cable of copper -core polyvinyl chloride, including a cable core, the cable core form by many insulation core and the transposition of optical fiber unit, copper -tape armor layer is woven to crowded package inner sheath outside the inner sheath outside the cable core, crowded package oversheath outside copper -tape armor layer. The utility model discloses fused fiber communication and power transmission's function, have the transmission of high reliability data, price low, connect characteristics such as convenient, the advantage has that the external diameter is little, light in weight, occupation space are little, has important status in the data transmission of following home intelligence, office automation, digital transformer substation, industry control networking.

Description

A kind of copper core polyvinyl chloride insulation steel-tape armouring optical fiber composite low-voltage cable

Technical field

This utility model is related to electric wire field, and in particular to a kind of copper core polyvinyl chloride insulation steel-tape armouring optical fiber is multiple Close low-voltage cable.

Background technology

As national grid increases the construction to intelligent grid, except backbone network builds high pressure, supertension Large Copacity energetically Outside transmission line of electricity, also power optical fiber is pushed to family in user side.On June 13rd, 2010, State Grid Corporation of China is in ShenYang, Liaoning Province City holds power optical fiber to family pilot work forum, indicates that power optical fiber is built to family pilot project and starts comprehensively.Optical fiber It is that power cable and communications optical cable are fused in a cable in place of composite low-voltage cable main innovation, the same of electric energy is being provided When, telecommunications network, broadcasting and television network, the same net signal transmission of the Internet are capable of achieving, it is more convenient and modernization to provide the user Life style.

Utility model content

In order to overcome the deficiencies in the prior art, there is provided a kind of copper core polyvinyl chloride insulation steel-tape armouring Optical Fiber Composite Low-voltage cable.

For achieving the above object, this utility model provides a kind of copper core polyvinyl chloride insulation steel-tape armouring fiber composite low-voltage Cable, including cable core, described cable core are formed by many insulated wire cores and fiber unit are stranded, are filled out in the gap of cable core Water blocking yarn is filled, inner sheath is extruded outside cable core, copper strips armor is woven outside inner sheath, outer shield is extruded outside copper strips armor Set.

Preferably, described insulated wire cores are made up of copper conductor and the polyvinyl chloride insulation layer being extruded in outside copper conductor.

Preferably, described fiber unit is made up of optical fiber and the protection pipe being arranged on outside fiber unit.

The beneficial effects of the utility model are：

Compared with prior art, power cable and communications optical cable compared with prior art, are fused to one by this utility model In root cable, while electric energy is provided, telecommunications network, broadcasting and television network, the same net signal transmission of the Internet are capable of achieving.In technology On realize, may replace conventional electric wire, netting twine, electricity The multiple construction of a plurality of circuits such as words line, cable television line, greatlys save cable resource and conduit resource；This utility model merges The function of fiber optic communication and power transmission, with high reliability data transmission, price it is low, it is easy to connect the features such as, advantage has External diameter is little, lightweight, it is little to take up room, in future home intellectuality, office automation, digital transformer substation, industry control network Data transfer in have consequence.

Description of the drawings

Fig. 1 is structural representation of the present utility model.

Specific embodiment

Below in conjunction with the accompanying drawings and specific embodiment, further elucidate this utility model, it should be understood that these embodiments are only used for Illustrate this utility model rather than limit scope of the present utility model, after this utility model has been read, art technology Modification of the personnel to the various equivalent form of values of the present utility model falls within the application claims limited range.

As shown in figure 1, this utility model provides a kind of copper core polyvinyl chloride insulation steel-tape armouring optical fiber composite low-voltage cable, Including cable core, described cable core is formed by many insulated wire cores and fiber unit are stranded, wherein, insulated wire cores are by copper conductor 1 and the polyvinyl chloride insulation layer 2 that is extruded in outside copper conductor constitute；Fiber unit is by optical fiber 4 and is arranged on outside fiber unit Protection pipe 5 constitute；In the gap filling water blocking yarn 3 of cable core, inner sheath 6 is extruded outside cable core, copper is woven outside inner sheath Band armor 7, extrudes oversheath 8 outside copper strips armor.

This utility model has merged the function of fiber optic communication and power transmission, with high reliability data transmission, price it is low, The features such as easy to connect, advantage, have that external diameter is little, lightweight, it is little to take up room, in future home intellectuality, office automation, number There is in Zi Hua transformer stations, the data transfer of industry control network consequence.

The above is only preferred implementation of the present utility model, it is noted that for the ordinary skill people of this area For member, on the premise of without departing from this utility model principle, some modifications and improvement can also be made, these also should be regarded as category In protection domain of the present utility model.
