Abstract
The invention discloses an optical-fibre composite low-voltage cable, comprising a cable core, wherein a filling layer is filled in a gap in the cable core, and a belting layer, an armouring layer and a jacket layer are concentrically wound outside the cable core in order; and the cable core is formed by concentrically twisting a low-voltage power cable insulated wire core with an optical cable. According to the optical-fibre composite low-voltage cable disclosed by the invention, a power cable and a communication optical cable are combined in one cable, and the co-network signal transmission of a telecommunication network, a broadcast and television network, and the Internet can be realized while electric energy is provided, and thus providing convenient and modern lifestyle for users.
Description
Technical field
The present invention relates to the power cable field, especially a kind of Optical Fiber Composite low-voltage cable.
Background technology
Along with national grid strengthens the construction to intelligent grid, except backbone network is built high pressure, superhigh pressure large capacity transmission circuit energetically, also try hard to recommend power optical fiber to the family at user side.On June 13rd, 2010, State Grid Corporation of China holds power optical fiber pilot work forum to the family in the ShenYang, Liaoning Province city, indicates that the pilot project construction starts power optical fiber comprehensively to the family.Optical Fiber Composite low-voltage cable main innovation part is that power cable and communications optical cable are fused in the cable; When electric energy is provided; Also realized the same net signal transmission of telecommunications network, broadcasting and television network, the Internet, for the user provides convenient more and modern life style.
And the weak point that exists in the present prior art is: prior art can only perhaps realize optical fiber communication by electric energy transmitting; Thereby cause the repeatedly construction of many circuits such as electric wire, netting twine, telephone wire, cable television line, wasted cable resource and conduit resource greatly.
Summary of the invention
The technical problem that the present invention will solve provides a kind ofly organically to be combined power cable core and optical cable, realizes that a cable can transmission of electric energy, can realize the compound low-voltage cable of the function of optical fiber communication again.
A kind of Optical Fiber Composite low-voltage cable of the present invention comprises cable core, and the space in cable core is filled with packed layer, and belting layer, armour and restrictive coating are set outside cable core successively with one heart; Said cable core is to be formed by lv power cable insulated wire cores and the optical cable system of twisting with one heart.
Said cable core adopts the strand system core structure of 2 cores+1,3 cores+1 or 4 cores+1 to form by lv power cable insulated wire cores and optical cable.
Described lv power cable insulated wire cores is coated with plastic insulating layer.
Described optical cable is non-metallic layer strand dry type optical cable, non-metallic layer strand filled type optical cable, nonmetal central tube dry type optical cable or nonmetal central tube filled type optical cable.
Said belting layer and packed layer are the fire proofing layer.
Said armour is a double-deck galvanized steel strip gap winding arrangement.
Said restrictive coating is for extruding the flame retardant plastics layer.
Beneficial effect of the present invention is:
1, the present invention is fused to power cable and communications optical cable in the cable; Once construction, the problem that passage, disposable solution cable are registered one's residence only needing have been realized technically; Instead is the repeatedly construction of many circuits such as electric wire, netting twine, telephone wire, cable television line in the past, practices thrift cable resource and conduit resource greatly.
2, the function of optical fiber communication and electric power transfer has been merged in the present invention, has characteristics such as high reliability data transmission, price be low, easy to connect, also has that external diameter is little, in light weight, advantage such as little takes up room.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of Optical Fiber Composite low-voltage cable of the present invention comprises cable core, and the space in cable core is filled with packed layer 4, outside cable core, is wound with belting layer 3, armour 2 and restrictive coating 1 successively with one heart; Described cable core is to be twisted with one heart to make with optical cable 5 by lv power cable insulated wire cores 6 to form.
Cable core of the present invention adopts the strand system core structure of 2 cores+1,3 cores+1 or 4 cores+1 to form by lv power cable insulated wire cores and optical cable, and said optical cable can be non-metallic layer strand dry type optical cable, non-metallic layer strand filled type optical cable, nonmetal central tube dry type optical cable or nonmetal central tube filled type optical cable; Lv power cable insulated wire cores 6 adopts plastic insulating layer to coat; Belting layer 3 is the fire proofing layer with packed layer 4; Armour 2 is a double-deck galvanized steel strip gap winding arrangement, and its gap is not more than 50% of bandwidth; Restrictive coating 1 is for extruding the environmental protection flame retardant plastic layer, its oxygen index＞35%.
The invention provides a kind of version and implementation method of Optical Fiber Composite low-voltage cable; The above only is a preferred implementation method of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement, these improvement also should be regarded as protection scope of the present invention.
