Technical field
The invention belongs to power cable technical field, be specifically related to a kind of height and fill the optoelectronic composite cable that blocks water.
Background technology
The primary structure of present composite rope is made up of cable core and sheath, core cross section is mostly circular, there is space by between the core that stranding is adjacent, because space can affect the compactness of the construction of cable, when using for a long time or be subject to extraneous extruding, cable can be made to deform.All to exceed and general cable for the structural integrity of composite rope and the requirement of degree of safety now, how ensure that the structural integrity of composite rope is a difficult problem.
In the use procedure that cable is long-term, due to the erosion of moisture and moisture, cause transmission performance to decline, impact normally uses.Particularly in southern area, through moisture, rainy, level of ground water is high, the water preventing ability of buried-pipe laying cable seems especially important, and user more and more needs one can prevent moisture and moisture attack, long-lived cable, to ensure the transmission performance of cable and normal use.
Because modern process is constantly accelerated, the requirement for cable is more and more higher, and the utilization of optoelectronic composite cable, mainly in order to multi-purpose, saves production cost, and therefore the demand of optoelectronic composite cable constantly becomes large.
Therefore, how improving high fillibility and the water preventing ability of electric wire, is the current technical issues that need to address of those skilled in the art.
Summary of the invention
The invention provides a kind of height and fill the optoelectronic composite cable that blocks water, there is good water preventing ability and high fillibility, and reduce the harm that environment is caused, electric supply and high-quality optical fiber can be provided in longer scope to ensure.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of height fills the optoelectronic composite cable that blocks water, comprise cable core and be coated on the protective jacket outside described cable core, described cable core is the conductor that electric unit and light unit are intertwined, and described protective jacket comprises outer protective polyethylene cover, steel band and polyethylene inner sheath from outside to inside.Adopt inside and outside double-layer polyethylene sheath and interlayer steel band as protective jacket, there is the anti-ultraviolet radiation performance of good mechanicalness, temperature characterisitic and excellence, electric supply and high-quality optical fiber can be provided in longer scope to ensure.Steel band effectively can stop biological the baiting and destroy such as mouse ant, protects the complete of internal structure and safety, can improve crushing resistance simultaneously, ensure that inner cable core normally works.
Preferably, aluminium strip and water blocking layer is also provided with from outside to inside between described polyethylene inner sheath and cable core.Ensure drying and the shield effectiveness of cable core internal structure, guarantee good insulation property.Water blocking layer can select the extraordinary ointment being applicable to protect optical fiber, ensures that optical fiber normally works.
Preferably, the space between described cable core and water blocking layer, space between electric unit and light unit are all filled with flexible polyurethane foams, are also provided with fire-proof heat-insulating reinforcement in the space between electric unit and light unit.Flexible polyurethane foams is adopted to fill, form the soft right foam matter packed layer of plasticity, inner structure is more compacted, even if be subject to extraneous extruding, cable also can remain unchanged shape, and flexible polyurethane foams to have water absorption high, the characteristic that water preventing ability is excellent, the moisture that seepage is come in can be absorbed, ensure that internal structure is dry.
Preferably, described fire-proof heat-insulating reinforcement is glass fibre belt.Glass fiber tape adopts high-temperature-resistant high type glass fibre, processes through special process.There is high temperature resistant, insulation, insulation, fire protection flame retarding, corrosion-resistant, ageing-resistant, the feature such as weatherability, high strength, smooth in appearance.Spun-glass insulation heat insulating belt, silicon rubber glass fibre is mainly divided into protect heat insulating belt, glass radiation proof heat-preserving heat-insulating belt etc.
Preferably, described steel band is double plastic-coated steel band.Double plastic-coated steel band has Corrosion Protection, can better paste ensure the tight and firm of wire structure with inner sheath and oversheath.
The invention discloses a kind of height and fill the optoelectronic composite cable that blocks water, adopt inside and outside double-layer polyethylene sheath and interlayer steel band as protective jacket, there is the anti-ultraviolet radiation performance of good mechanicalness, temperature characterisitic and excellence, electric supply and high-quality optical fiber can be provided in longer scope to ensure.And aluminium strip and water blocking layer are set between protective sleeve and cable core, have ensured drying and the shield effectiveness of cable core internal structure, guaranteed good insulation property.Water blocking layer can select the extraordinary ointment being applicable to protect optical fiber, ensures that optical fiber normally works.
