Abstract
The utility model discloses a high-flame-retardant self-test composite optical fiber cable. The cable comprises an outer sheath, an inner sheath, multiple groups of cabling cores arranged in the inner sheath and an optical unit. The cable is characterized in that each cabling core is formed through twisting a power core, the optical unit and a structure filler; each cabling core comprises a conductor and a cladding insulating layer outside the conductor; the cladding insulating layer comprises three layer structures; an inner layer is an inner insulating layer, a middle layer is a flame retardant coating layer and an outer layer is a subunit outer sheath; sensing fibers are uniformly arranged between the inner insulating layer and the flame retardant coating layer. Compared to the prior art, by using the cable of the utility model, through uniformly arranging the sensing fibers on an outer side of the insulating layer, accurate monitoring can be performed on an elevator cable; when the sensing fibers are fractured, fracture positions can be clearly found out through an elevator system so that an accident can be prevented and usage is safe.
Description
Technical field
The utility model belongs to the cable technology field, is specifically related to a kind of high flame retardant from detecting the composite fiber cable.
Background technology
The intelligent power technology is one of important technical of building intelligent grid.Along with the propelling of State Grid Corporation of China's intelligent grid building-up work, intelligent grid, intelligent power technology will lead the new trend of electric power application, and optical fiber composite low-voltage cable (OPLC) will become the preferred option of intelligent grid user incoming end.Fiber entering household is the inherent requirement of development intelligent grid, adopt optical fiber composite low-voltage cable to register one's residence and can advance network overall planning and Joint construction and sharing, reduce the implementation cost of the integration of three networks, not only save water, electricity, the gas meter copying work cost of working in a large number, avoid unnecessary repeated construction, building industry and resident living comprehensive energy consumption are further reduced, realize remote collection and home furnishings intelligent electrical energy consumption analysis and the control of the gauge table information such as electricity, water, coal gas, for the user provides more energy-conservation modern service for life.The employing optical fiber composite low-voltage cable has been realized to family only need once constructing technically, the problem that passage, disposable solution cable are registered one's residence, and greatly saves cable resource and conduit resource.Optical fiber composite low-voltage cable, as a kind of cable with good physical, is being applied to the building vertical shaft, when elevator and other wiring vertical shafts, often has the high flame retardant characteristic and resists and prolong the combustion characteristic, and can embody the Function in Environmental of cable.Chinese patent CN201210492297.9 discloses a kind of novel high flame retardant optical fiber composite low-voltage cable, it comprises cable core, is coated on the outer fire retardant of cable core and the outer oversheath of fire retardant, improvements are: described cable core is by power unit and light unit and the structure filling thing is stranded forms, described power unit comprises conductor and the outer coated insulation layer of conductor, described coated insulation layer has three-decker, and internal layer is that inner insulating layer, intermediate layer are that flame retardant cover, skin are the subelement outer jacket.The characteristics of this patented technology are to have the high flame retardant characteristic and resist prolongs the combustion characteristic, uses simultaneously a large amount of butanedionedioxime technology and material, can effectively embody the Function in Environmental of cable.In a single day but also there is an obviously deficiency, namely use the life-span to fall short of, and break down, be difficult to detect timely and accurately the cable damaged location, be difficult for changing and maintenance.In addition, heat-proof quality is not good yet.
The utility model content
The purpose of this utility model is to provide a kind of high flame retardant of new construction from detecting the composite fiber cable, pass through architecture advances, not only more can tolerate various environment, longer service life, and when the faults such as the disconnected core of cable generation, the cable damaged location can be detected timely and accurately, easy to replace and maintain.
for realizing this purpose, the technical solution of the utility model is: a kind of high flame retardant is from detecting the composite fiber cable, comprise oversheath, inner sheath and be located at many compositions cable core and the light unit in inner sheath, described one-tenth cable core is by power core and light unit and the structure filling thing is stranded forms, described one-tenth cable core comprises conductor and the outer coated insulation layer of conductor, described coated insulation layer has three-decker, internal layer is inner insulating layer, intermediate layer is flame retardant cover, skin is the subelement outer jacket, between described inner insulating layer and flame retardant cover, evenly be provided with the sensing fiber.
As preferably, described flame retardant cover is the netted skeleton structure of internal layer.
As preferably, outside described coated insulation layer, be coated with by the wrapped thermal insulation layer that forms of some polymethyl methacrylate silk ribbons.
As preferably, described thermal insulation layer is coated with by the wrapped heat insulation reinforced layer that forms of some high temperature resistant stainless steel alloy silk ribbons.
With respect to prior art, the utility model on the one hand can be under 800 ℃ of flame conditions can load running 30 minutes, and do not produce poisonous aerosol, for fire extinguishing, rescue the more time of winning, reduce casualties and property loss.The flame retardant cover cladding material has high heat expansion technique simultaneously, and while making cable stand the naked light infringement, coating layer effectively expands, and stops outside oxygen-containing gas at the cable internal convection, thereby effectively controls rate of propagation.In the insulating barrier outside, evenly be provided with the sensing fiber on the other hand, can monitor accurately elevator cable, when sensing fibrous fracture, by elevator device, clearly find fracture position, try to avert accidents, use safer.The thermal insulation layer that arranges simultaneously and heat insulation reinforced layer play a very good protection when the breaking out of fire to cable.
