Abstract
The utility model discloses an optical fiber composite low-voltage cable, which comprises a cable core, a belting layer, a lining layer, an armor layer and an external protection layer, wherein the belting layer, the lining layer, the armor layer and the external protection layer are sequentially wrapped outside the cable core from the inside to the outside. The optical fiber composite low-voltage cable is characterized in that the cable core comprises four electrical units, an optical unit and a sector-annular filling unit, wherein one of the four electrical units is a round electrical unit, the other three electrical units are sector-annular electrical units, the three sector-annular electrical units and the filling unit sequentially cling to define a sector ring, and the inner lateral faces of the sector-annular electrical units and the filling unit cling to the round electrical unit. The optical unit is arranged in the filling unit, and the round electrical unit, the sector-annular electrical units, the optical unit and the filling unit are intertwisted to form the cable core. The optical fiber composite low-voltage cable has the advantages that due to the fact that the three electrical units of the cable core are processed to be sector-annular and to cling to the round electrical unit, structure of the integral cable core is compact, external diameter of finished products is shortened, filling quantity of filling objects is reduced, use quantity of steel belts and other auxiliary materials and external protection materials is reduced, and cost is reduced.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of Optical Fiber Composite low-voltage cable.
Background technology
The Optical Fiber Composite low-voltage cable is a kind of lv power cable cable mutually compound with the light unit, and electric power and transmission of Information can be provided simultaneously, and it is applicable to rated voltage 0.6/1 kV and following electric pressure.Electric unit in this cable conductor all is a circular configuration at present, and technology controlling and process is comparatively simple with operation, but the gap between heavy in section electric unit is very big; And in order to guarantee the outward appearance rounding of finished cable; Need to fill a large amount of packing materials in the gap between electric unit, this makes that the external diameter of cable core is very big, causes the corresponding increase of auxiliary material such as steel band and outer sheath material consumption; Promptly increased cost, made troubles also for packing, transportation etc.
Summary of the invention
It is compact that the utility model technical problem to be solved provides a kind of construction of cable that makes, the Optical Fiber Composite low-voltage cable that the finished product external diameter is little and cost is low.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the Optical Fiber Composite low-voltage cable; Comprise cable core and be coated on described cable core outer belting layer, inner covering, armour and outer jacket from inside to outside successively; Described cable core comprises four electric units, a light unit and fans the filler cells of annular; In described four electric units wherein one be circular electric unit; Its excess-three root is fan annular electro unit, and three fan annular electro unit are close to successively with filler cells and are surrounded a fan ring, and medial surface and the circular electric unit of fanning annular electro unit and filler cells are close to; Described smooth unit is arranged in the described filler cells, the whole stranded formation cable cores of described circular electric unit, fan annular electro unit, light unit and filler cells.
Described electric unit comprises conductor and insulating barrier.
Described smooth unit comprises multifiber and the loose sleeve pipe, non-metal reinforced layer and the sheath that set gradually from inside to outside; Described loose casing pipe sleeve is outside described optical fiber; Fill full dry type water-blocking material in the described loose sleeve pipe; Be provided with many equally distributed water blocking yarns in the described non-metal reinforced layer, be embedded with between described non-metal reinforced layer and the described sheath and tear rope.
The material of described non-metal reinforced layer is the high strength fibre yarn.
The material of described filler cells is a polyolefin.
Compared with prior art; The utility model has the advantages that since with in the cable core wherein three electric units and filler cells to be processed into fan annular, and be close on the circular electric unit, make the compact conformation of whole cable core; Dwindled the external diameter of finished product; And reduced the loading of filler, and also reduced the consumption of auxiliary material such as steel band and outer sheath material, reduced cost; In addition, adopt the high strength fibre yarn to do the material of non-metal reinforced layer in the light unit, improved the mechanical performance of light unit, also prolonged the useful life of cable.
