Abstract
The utility model relates to a high temperature and voltage resistant optical cable which can be used in a large temperature range. The optical cable includes a fiber and is characterized in that the outside of the fiber is coated with a high temperature resistant buffer layer, an aramid fiber reinforced fibrous layer, and a high temperature resistant outer protective layer in order. The optical cable can be used for a long time in a wide temperature scope from -55 to +150 DGE C. The optical cable is strong in ageing resistance, stable in light transmission performance, and low in light added loss along with the environmental temperature change, and is resistant to the voltage of above alternating current 80kV/m, and can realize the optical communication application in aviation aircraft and electric power high voltage resistance severe service environments.
Description
Technical field
The utility model relates to a kind of high temperature resistant high voltage withstanding optical cable that can in big temperature range, use.
Background technology
Along with the continuous development of optical fiber technology, optical fiber cable has obtained application widely such as fields such as military affairs, electric power, engineering monitoring (sensing), petrochemical complex and medical science beyond the telecommunications industry.Some special dimensions particularly, optical fiber cable advantages such as big and anti-electromagnetic interference capability is strong with its transinformation are more and more paid attention to and are favored.Existing conventional communications optical cable temperature resistant grade is lower, and the serviceability temperature scope is narrow, is generally-40 ℃～70 ℃, and some are in the communicating requirement under the harsh environments for use such as high temperature, high voltage and chemical industry erosion for a long time to be difficult to satisfy aviation aircraft etc.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of high temperature resistant and anti-high-voltage performance good high temperature resistant high voltage withstanding optical cable to the deficiency that above-mentioned prior art exists.
The present invention for the technical scheme that problem adopted of the above-mentioned proposition of solution is: include optical fiber, it is characterized in that outside optical fiber, coating successively high temperature resistant cushion, aramid fiber fortifying fibre layer and high temperature resistant outer jacket.
Press such scheme; Described optical fiber is high-temperature resistant optical fiber; Described high-temperature resistant optical fiber is a coating polyimide coat outside bare fibre; The coating external diameter of polyimide coated layer is 0.15～0.16mm, or outside bare fibre, applies high temperature resistant acrylate resin coat, and the coating external diameter of high temperature resistant acrylate resin coat is 0.24～0.25mm.
Press such scheme, described fiber number is 1～3.
Press such scheme, described fiber number is 1, constitutes single fiber cable.
Press such scheme, described high temperature resistant cushion is made up of heat resist modification silicon rubber or high temperature resistant acrylate resin, and high temperature resistant cushion external diameter is 0.75～0.95mm.
Press such scheme, described high temperature resistant outer jacket is made up of fluoroplastic ETFE or FEP or PFA, and high temperature resistant outer jacket external diameter is 1.8～3.0mm.
Press such scheme, described aramid fiber fortifying fibre layer is an aramid fiber knitted body structural sheet.
The beneficial effect of the utility model is: 1, the high temperature resistant cushion of big external diameter can guarantee under high low temperature environment for use; The contraction of high temperature resistant outer jacket is unlikely to cause inner optical fiber to produce serious little bending, and then guarantees still have less loss when optical cable is in high and low temperature environment; 2, be uniformly distributed in the outer aramid fiber fortifying fibre layer of high temperature resistant cushion; Give optical cable high tensile ability on the one hand; On the other hand, when optical cable is in harsh high low temperature environment for use, guarantee that the internal damping layer evenly bears the differential contraction stress that outer jacket gives; Make unlikely little bending, the normal optical signal transmission of assurance optical cable of producing because suffered unbalanced stress even of optical fiber; 3, the optical cable of the utility model can use in-55 ℃～+ 150 ℃ wide temperature range for a long time; Ageing resistance is strong; Has highly stable optical transmission performance; Light added losses with variation of ambient temperature are extremely low, and can tolerate at least up to the voltage that exchanges 80kV/m, can satisfy the optical communication applications in harsh environment for use fields such as aerospace flight vehicle, electric power be high voltage withstanding.
