Along with working environment and living environment are improved needs by industrial automation and people, distant control and centralized Control have become as the normality of office automation.For inflammable and explosive places such as chemical industry, combustion-gas jet test storages, it is necessary to use intrinsic safety electrical system.For connecting cable intrinsic safety the to be used cable of on-the-spot and control system.Conventional intrinsic safety cable has used for many years, most of occasions use ideal, but in accurate control with there is vibrations occasion problem to highlight, there is noise considerable influence control equipment properly functioning as being connected with light-sensitive device and surveying the intrinsic safety cable distribution signal of shake device connection.Problem above scene is repeatedly studied test, finally finds that noise produces, essentially from Exterior cable sensing and cable, the voltage pulsation that triboelectrification causes certainly in vibrations, develop this utility model military low noise intrinsically-safe instrument cable for solving problem above.
Utility model content
This utility model provides a kind of compact conformation to solve problem above, reduces triboelectrification effect, capacity of resisting disturbance is strong, shield effectiveness good, easily manufactured, production cost is low New Type Military low noise intrinsically-safe instrument cable.
The technical solution of the utility model is: described cable includes some insulated wire cores, if every two or three of described some insulated wire cores are twisted into main line group, the outer wrapped sub-shield of each line group, described sub-shield is made up of the tin-coated copper silk screen of braiding outside double-sided aluminum foil and double-sided aluminum foil, the outer wrapped mylar of described sub-shield, if being provided with semiconductive PP rope between described main line group to fill, if the common wrapped total screen layer of described main line group, described total screen layer is made up of the tin-coated copper silk screen of braiding outside double-sided aluminum foil and double-sided aluminum foil, restrictive coating is extruded outside total screen layer, described insulated wire cores includes some conductors, described conductor is externally provided with one layer of semiconductive film, Low Density Polyethylene insulating barrier is extruded outside described semiconductive film, semi-conductive layer is extruded outside described insulating barrier.
Described conductor is 1 or 2 or 5 class conductor copper wires, and copper wire is that purity reaches 99.99% oxygen-free copper material, stranded rear conductor rounding, and monofilament uses cold welding welding.
Described semiconductive film conductor when extruded insulation layer crosses ultra-fine carbon black, and ultra-fine carbon black forms semiconductive film with Low Density Polyethylene inner insulative surface.
Described conductor used heater that copper wire is heated to 80-90 degree before crossing ultra-fine carbon black.
Described insulating barrier and semi-conductive layer use double-layer coextrusion, semi-conductive layer thickness between 0.1mm and 0.2mm, insulating barrier and semi-conductive layer close adhesion.
In described sub-shield and total screen layer, tin-coated copper silk screen coverage rate is not less than 85%.
Described restrictive coating is fire-retardant blue pvc sheath.
Problem to be solved in the utility model is the voltage pulsation caused from generation triboelectrification in vibrations from Exterior cable sensing and cable, shielding properties is increased for solving outside sensing, the surface having movement for solving triboelectrification in the construction of cable between element increases semiconductive material, reduce triboelectrification and electrostatic charge export plan is solved, add semi-conductive layer inside and outside insulation compared with intrinsically-safe instrument cable, play minimizing triboelectrification effect；Employing double-sided aluminum foil shields, and reduces from external disturbance.
