Description
Technical field
The utility model relates to electric wire field, specifically refers to a kind of novel reinforced type external optical fiber power cable.
Background technology
Along with the development of society, the progress of science and technology, numerous power plant, smelter, oil play are to large-scale grouping of the world economy future development, skyscraper, public entertainment place, subway and underground street etc. continue to bring out, and its power consumption grows with each passing day, and the kind of electric wire and consumption be corresponding increase also.Electric wire both can transmission & distribution electric energy, transmission of information, be again fire hazardous " blasting fuse ", but common cable just cannot be energized once burned when actual breaking out of fire.But during many important events event of fire, the illumination of evacuating personnel, passage, fire protection alarm device, automatic fire-fighting facility and other emergency set all require that cable can keep normal power-up at the appointed time when fire occurs.Therefore, people work out fireproof cable.
Fireproof cable refers to that, under regulation experimental condition, sample is burned in flame, still keeps the normal performance run within a certain period of time.Its basic feature is exactly: power cable still can maintain the normal work of this circuit a period of time under burning condition.Be exactly generally that fireproof power cable can maintain the normal power supply of a period of time when fire occurs, to maintain illumination and signal transmission, protection personnel have time enough safe escape, and are beneficial to fire extinguishing and reduce the loss.
China's most area belongs to temperate climate, and rainfall snowfall is many, and groundwater resources enrich, and cable is generally laid on underground, requires higher to protection against the tide.In order to improve the water preventing ability of cable, people take to apply material water-proof material outward at the cable core of cable usually, composition water repellent electric cable.But material water-proof material is relative to common insulating material, thermal resistance is relatively large, seriously hinders the proper heat reduction of cable, thus causes electric cable heating amount to increase.Increasing of electric cable heating amount, can cause the reduction of cable transmission power on the one hand; Core can be made on the other hand to insulate accelerated ageing of being heated.After ageing of insulation, block-water performance reduces, and moisture enters insulation and then enters cable joint along insulation longitudinal flow, thus cable may be caused to blast.
In addition, the cable conductor structure of prior art is easily extruded distortion, even ruptures, and have impact on conductivity and the useful life of cable.
In sum, the deficiency that prior art exists, flexible poor, water proofing property is poor, fire resistance is poor, is easily bent arbitrarily and draws, easily cause disconnected core in the use procedure of cable.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of flexibility is good, water preventing ability is good, fire resistance is good, production cost is low, the novel reinforced type external optical fiber power cable of Stability Analysis of Structures, long service life.
One described in the utility model novel reinforced type external optical fiber power cable, comprising: cable core triangular in shape, weaves belting layer outward at cable core, extrudes metal armor layers outside belting layer, extrudes oversheath at cable core outermost layer; Described cable core is combined by an insulated wire cores, reinforced core, a control conductor and a tripod; Described two are connected to each other by the reinforcement with supporting role between strengthening core and insulated wire cores, are respectively provided with a fiber unit at three angles place of tripod, have at least an inside to be provided with multifiber in three fiber units.
Further improvement, described insulated wire cores is made up of conductor and insulating layer of conductor, insulation screen and the flame retardant coating be coated on successively outside conductor.
Further improvement, described reinforced core is made up of steel wire rope and the protective layer be extruded in outside steel wire rope and armouring screen.
Further improvement, described control conductor is by the control insulating layer of conductor controlling conductor and be extruded in successively outside control conductor and restrictive coating.
Further improvement, described cable core gap is provided with water blocking yarn packed layer.
Further improvement, the gap outside described cable core and between belting layer is provided with fire-resistant isinglass belt.
Further improvement, when the optical fiber in described fiber unit is many, is isolated by wire harness silk between optical fiber and optical fiber.
The beneficial effects of the utility model are:
Compared with prior art, the construction of cable of the utility model design, cable core, by adding tripod, is provided with metal armor layers outside cable core, the combination of inner and outside, and structure is more stable, is not easily extruded distortion, fracture, ensure that the conductivity of cable, long service life; In addition, fill some material water-proof materials and refractory material, add block-water performance and the fire resistance of cable, thus add the insulating properties of cable, through-put power, also can not cause blast because of aging, add fail safe.Also be provided with reinforced in this cable, more firm and stable to the overall structure of cable; In addition, three angles place of the inherent fixture of this cable is provided with fiber unit, is arranged on corner, not easily be extruded to, just can be good at realizing photoelectric unification, while electric energy transmitting, the same net Signal transmissions of telecommunications network, broadcasting and television network, the Internet can be realized.
