Description
Technical field
The utility model relates to a kind of cable, particularly a kind of transducer irradiation polyurethane flexible cable.
Background technology
Weighing apparatus is the important metrical instruments of people in producing and living, and nearly all industry all be unable to do without the application of weighing apparatus, thereby occupies considerable status in national economy.Weighing apparatus is widely used in the every field such as business metering, trade settlement, accurate control, security monitoring, monitoring resource.The high-precision weighing transducer is the heart of various precise electronic weighing apparatus.LOAD CELLS is generally described sensor performance with 21 Separation Indexes such as linear, hysteresis, repeatability, international metering tissue (OIML) general purpose transducer error is described, usually the LOAD CELLS that meets the above error requirements of C3 level is called high-precision sensor, and C6 level transducer is the highest transducer rank of Vehicles Collected from Market precision.Along with the development of sensor accuracy grade, transducer is also more and more higher to the requirement of cable, and sensor cable is to miniaturization, lightweight, high temperature resistant and stable, the super future development such as flexible.General sensor cable adopts the materials such as polyvinyl chloride, low-pressure polyethylene as sheath material, and insulating barrier is the materials such as polyethylene, polyvinyl chloride, and this type of product hardness is larger, is not easy bending, and low temperature tolerance ability is poor, can not satisfy novel demand for development.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides transducer irradiation polyurethane flexible cable.
The utility model for achieving the above object, the technical scheme of taking is: a kind of transducer irradiation polyurethane flexible cable, it is characterized in that: insulated wire cores, ground wire, aluminum composite belt foil shielding layer, EU restrictive coating that the conductor that included consists of with the crosslinked polyetylene insulated layer of one deck outward, four described insulated wire cores strandings vertically successively outside it are put a ground wire, wrapped one deck aluminum composite belt foil shielding layer, are extruded one deck EU external sheath layer.
The beneficial effects of the utility model are:
1, high temperature resistant: because inner wire has adopted tinned copper conductor, when normal, heatproof can reach 200 ℃, extrude the layer of polyethylene insulating barrier and consist of insulated wire cores outside inner wire, the integral insulation core forms crosslinked polyetylene insulated layer through radiation treatment, cross-linking polyethylene materials heatproof after cross-linking radiation all can reach 120 ℃, and solved the heat-shrinkable problem of polythene material, can stand the ageing test of 300 ℃ * 7H; Low temperature resistant: the temperature that works long hours of the cross-linking polyethylene materials after cross-linking radiation can reach-100 ℃, can be used for the place of limit low temperature.
2, anti-bending: conductor adopts 19 0.16mm synnemas, crosslinked polyetylene insulated layer average thickness only has 0.28mm, and ground wire adopts 7 0.2mm synnemas, and sheath adopts the EU material, the flexible degree of whole cable is high, can realize 3 times to the bending of existing cable diameter.
3, good mechanical property: the intensity of the cross-linking polyethylene materials after cross-linking radiation is very high, has the very high anti-ability of cutting, and has greatly improved the mechanical performance of insulation, and its intensity on average can reach 40Mpa.Sheath adopts the EU material, and wear-resistant, the anti-ability of pulling, antiacid alkali ability get a promotion, and can long-term work arrive in the scopes of 80 degree above freezing at subzero 60 degree of temperature range.
4, fire-retardant: the oxygen index of the cross-linking polyethylene materials after the employing cross-linking radiation can reach 40, has very high fire resistance.
5, softness: because conductor has adopted the stranded formation of the superfine tinned copper wire of 0.16mm, so greatly improved the flexibility of cable, cable is easy to laying installation.
6, shield effectiveness is good, uses aluminum composite belt as screen, and the wrapped rate of putting up is more than 15%, and shield effectiveness can reach more than 95%.
Description of drawings
Fig. 1 is structural representation of the present utility model.
