Abstract
A kind of photoelectric compound cable, relates to the design field of photoelectric compound cable.The utility model comprises cable core, and cable core forms by Stranded cable, an optical cable and strengthening core are stranded; Strengthening core is arranged in the center of cable core; Waterstop lapping layer, LSOH anti-flaming polyethylene material inner covering, vertical bag double plastic-coated steel-tape armouring layer and low smoke halogen-free flame-retardant polyolefin external sheath layer is set gradually outside cable core; The solid-state packed layer that blocks water of cable core is set between cable core and waterstop lapping layer; Per share cable comprises conductor respectively, at conductor arranged outside insulating barrier; Optical cable comprises optical fiber, is nested with Loose tube in outer fiber, arranges the solid-state packed layer that blocks water of sleeve pipe between optical fiber and Loose tube.The utility model close structure, block-water effect are good, the termite-proof performance of protection against rodents is excellent, Signal transmissions is safe and reliable, cost is low, construction maintenance is convenient, environmental protection.
Description
Technical field
The utility model relates to the design field of photoelectric compound cable.
Background technology
Become today of national strategy in " the Internet+", promoted the high speed development of information industry, application and the technological innovation of optical fiber cable are also more and more paid attention to by industry.Traditional optoelectronic composite cable reaches block-water effect mainly with water blocking yarn and greasy for preventing water, and water blocking yarn is easy fracture in process of production, and the surface shed powder that blocks water can affect block-water effect; There is not easy cleaning, resistance to low temperature difference and the defect such as high temperature drip in ointment, constructs and safeguard more complicated.South China Tropical subtropical zone mouse, termite damage are serious, and Traditional photovoltaic composite cable does not possess that protection against rodents is termite-proof bites the performance of stinging.
Utility model content
The utility model object is for above problem, provides a kind of and has close structure, block-water effect is good, the termite-proof performance of protection against rodents is excellent, Signal transmissions is safe and reliable, cost is low, construction maintenance is convenient and the photoelectric compound cable of the characteristic such as environmental protection.
The utility model comprises cable core, and described cable core forms by Stranded cable, an optical cable and strengthening core are stranded; Described strengthening core is arranged in the center of cable core; Waterstop lapping layer, LSOH anti-flaming polyethylene material inner covering, vertical bag double plastic-coated steel-tape armouring layer and low smoke halogen-free flame-retardant polyolefin external sheath layer is set gradually outside described cable core; The solid-state packed layer that blocks water of cable core is set between described cable core and waterstop lapping layer; Per share described cable comprises conductor, respectively at described conductor arranged outside insulating barrier; Described optical cable comprises optical fiber, is nested with Loose tube in described outer fiber, arranges the solid-state packed layer that blocks water of sleeve pipe between described optical fiber and Loose tube.
The beneficial effects of the utility model are: (1) fills and cable core outer cladding waterstop owing to adopting dry type high-performance intumescent water blocking yarn, waterproofing rope between each unit of cable core, optical cable is made to have better block-water performance, because electric cable heating reduces the viscosity of filling fine cream in light unit Loose tube when overcoming optical cable transferring electric power, fine cream is caused to sink and water clock and affect the defect of reduction light unit communications performance.Simultaneously weight reduction clean environment firendly.(2) in cabling process, with the addition of center strengthening core, enhance the toughness of core, light unit is placed on into the avris of cable core simultaneously, thus avoid the generation of core frangibility phenomenon in manufacture and transport or work progress.(3) adopt termite-resistant rodent-resistant low-smoke non-halogen flame-retardant improved polyalkene material to do oversheath, in oversheath, arrange vertical bag double plastic-coated steel-tape armouring layer, lateral pressure resistant ability is strong, has the ability of the excellent termite-proof destruction of protection against rodents, improves the useful life of cable.
It is fiberglass reinforced plastics that the utility model states strengthening core.
The solid-state packed layer that blocks water of cable core described in the utility model is waterproofing rope.
The solid-state packed layer that blocks water of sleeve pipe described in the utility model is water blocking yarn.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises cable core 1, and cable core is by Stranded cable 2, optical cable 3 and fiberglass reinforced plastics strengthening core 4 is stranded forms; Fiberglass reinforced plastics strengthening core 4 is arranged in the center of cable core 1; Waterstop lapping layer 5, LSOH anti-flaming polyethylene material inner covering 6, vertical bag double plastic-coated steel-tape armouring layer 7 and low smoke halogen-free flame-retardant polyolefin external sheath layer 8 is set gradually outside cable core 1; Waterproofing rope packed layer 9 is set between cable core 1 and waterstop lapping layer 5; Per share cable 2 comprises conductor 10 respectively, at conductor 10 arranged outside insulating barrier 11; Optical cable 3 comprises optical fiber 12, is nested with Loose tube 13 outside optical fiber 12, arranges water blocking yarn packed layer 14 between optical fiber 12 and Loose tube 13.
