Background technology
Existing power cable and optical cable are made separately; for the occasion difference cable laying and the optical cable that need electric power transfer and optical signal transmission simultaneously; finally cause the increase of expensive and difficulty of construction; this problem is perplexing the user; in order to address this problem; people have designed the Optical Fiber Composite lv power cable; be by the light unit; insulated wire cores; filler; oversheath and presumable armour and inner sheath etc. are partly formed; be generally round or parallel structure; the light unit is placed on cable inside or middle, makes tension; the light unit of resistance to compression and shock resistance difference obtains better protect.This class is placed on the inner or middle structure of cable to the light unit, earlier inner light unit and insulated wire cores is carried out light unit and electric unit respectively when continuing and continues, and then the integral body place of continuing is sealed in the splice tray; In case light unit or insulated wire cores local damage occur in construction or use, continue again after then needing whole cable to disconnect, optical fiber communication and power supply are interrupted simultaneously, and the complexity that continues, long, equipment cost height of activity duration.
Because the defective that above-mentioned existing Optical Fiber Composite lv power cable exists, the design people is actively studied innovation, in the hope of founding a kind of 8 font Optical Fiber Composite lv power cables of new structure, makes it have more practicality.
The utility model content
Main purpose of the present utility model is, overcomes the defective that existing Optical Fiber Composite lv power cable exists, and effectively reduces cost and difficulty of construction, guarantees the normal transmission of signal simultaneously, thereby is suitable for practicality more, and have the value on the industry.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to the 8 font Optical Fiber Composite lv power cables that the utility model proposes, the optical cable that comprises cable, the dowel that is provided with first oversheath and be provided with the vertical bag FRP band and second oversheath, first oversheath and second oversheath are connected to form 8 fonts by dowel, described cable comprises insulated wire cores, filler, oversheath, and perhaps cable also comprises armour and inner sheath.Optical cable comprises the loose sleeve pipe that contains multifiber and fine cream, and the radical of loose sleeve pipe is single or many, necessary strengthening core and gasket for packing, and material water-proof material is filled in the gap, vertical bag FRP band, oversheath.
The purpose of this utility model and solve its technical problem and also can be applied to the following technical measures to achieve further.
Aforesaid 8 font Optical Fiber Composite lv power cables, wherein said cable and described optical cable are the structure of independent completion, also can not destroy the integrality of first oversheath and second oversheath after described cable and described optical cable are broken separately from the dowel position; Vertical bag FRP band is vertical continuous transverse circle in optical cable, thickness 0.5～1.5mm, tensile strength 〉=1.1 GPa, modulus of elasticity 〉=50 GPa, elongation at break≤4.0%; Described first oversheath, second oversheath and dowel are with a kind of polyvinyl chloride or polyolefin jacket material.
By technique scheme, the beneficial effect of the utility model 8 font Optical Fiber Composite lv power cables is:
The utility model links into an integrated entity cable and optical cable with dowel, lay, synchronous when using, continue or when repairing damage location can two parts separately, continue separately or repair, simplify greatly and continue or repair process, reduce integrated cost.Simultaneously; vertical bag one deck FRP band is as reinforcement in optical cable; has good physical mechanical strength; effectively protected the optical fiber in the Optical Fiber Composite lv power cable; improved the performance such as resistance to compression, shock resistance, bending of Optical Fiber Composite lv power cable; make the photoelectricity composite power cable in cable laying operation and use; reduce optical fiber communication and power supply interrupt probability simultaneously; and because of having adopted non-metal reinforcement member; when cable section damages, reduced influence, improved the reliability of security of products and system the optical cable part.In sum, 8 font Optical Fiber Composite lv power cables of the utility model special construction, it has above-mentioned many advantages and practical value, thereby is suitable for practicality more.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.
