Abstract
The utility model relates to a novel insulation shielding cable, comprising three conductors. A PVC insulation layer is wrapped outside of every conductor. Thickness of the PVC insulation layer is between 0.5-0.6 mm. A filling layer is arranged outside of the PVC insulation layer. A first tape layer is arranged outside of the filling layer. A shielding layer is arranged outside of the first tape layer. A second tape layer is arranged outside of the shielding layer. A sheath layer is mounted outside of the second tape layer. The cable provided by the utility model has a good insulation shielding effect and relatively high integral structure intensity and can be applied to electromagnetic and other complex environments.
Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of insulation shielding cable.
Background technology
Along with the fast development of national economy, as the aortal electric wire of national economy, its consumption and the scope of application are increasing.In recent years, the industries such as power plant, transformer station, smelting and petrochemical industry, very big to the demand of control cables, more abominable in electromagnetic environment especially, the installation site that mounting distance is less.
Generally speaking, electromagnetic shielded cable structure from the inside to the outside is followed successively by core, the insulating medium layer that is coated on the cable core outer surface, screen and the oversheath that forms inner wire.Wherein, cable core is used for transmission of electric signals, and material is take copper or ormolu as main.Screen is generally layer of metal foil, disturbs in order to shield electromagnetic interference or useless external signal.Overlay on the screen that insulating medium layer forms outward for layer of metal foil volume, be covered in outside the insulating medium layer after need being pre-formed layer of metal foil.This type of screen well below the speed of production of cable system core, is the principal element of restriction electromagnetic shielded cable volume production on speed of production.
In sum, necessaryly provide a kind of insulation shielding effective, intensity is high, can adapt to all-environment electromagnetic shielded cable.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of insulation shielding effective, and overall construction intensity is higher, can be applied to the New insulated shielded type cable under the complex environments such as electromagnetism.
Technical scheme: in order to solve the problems of the technologies described above, a kind of New insulated shielded type cable described in the utility model, it comprises three conductors, the polyvinyl chloride insulation layer is all wrapped up in outside at every conductor, the thickness of this polyvinyl chloride insulation layer is between 0.5-0.6mm, outside described polyvinyl chloride insulation layer, be provided with packed layer, outside described packed layer, be provided with the first belting layer, outside described the first belting layer, be provided with screen, outside described screen, be provided with the second belting layer, outside described the second belting layer, be provided with restrictive coating.
Described conductor is copper conductor or tinned copper conductor.
Described screen is that copper wire or tinned copper wire braiding form, and its density is greater than 90%.
Described restrictive coating is flexible polyvinyl chloride restrictive coating or halogen-free and low-smoke flame-retardant polyolefin sheathed layer.
Described packed layer is composite material of silicon carbide packed layer or asbestos packed layer.
Described the first belting layer and the second belting layer are the polyester belt lapping layer.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model adopts density greater than the screen that 90% copper wire or tinned copper wire braiding form, and can reach good shield effectiveness.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein:
1, conductor; 2, polyvinyl chloride insulation layer; 3, packed layer; 4, the first belting layer; 5, screen; 6, the second belting layer; 7, restrictive coating
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, a kind of New insulated shielded type cable described in the utility model, it comprises three conductors 1, polyvinyl chloride insulation layer 2 is all wrapped up in outside at every conductor 1, the thickness of this polyvinyl chloride insulation layer 2 is between 0.5-0.6mm, outside described polyvinyl chloride insulation layer 2, be provided with packed layer 3, outside described packed layer 3, be provided with the first belting layer 4, outside described the first belting layer 4, be provided with screen 5, outside described screen 5, be provided with the second belting layer 6, outside described the second belting layer 6, be provided with restrictive coating 7; Described conductor 1 is copper conductor or tinned copper conductor; Described screen 5 is that copper wire or tinned copper wire braiding form, and its density is greater than 90%; Described restrictive coating 7 is flexible polyvinyl chloride restrictive coating or halogen-free and low-smoke flame-retardant polyolefin sheathed layer; Described packed layer 3 is composite material of silicon carbide packed layer or asbestos packed layer; Described the first belting layer 4 and the second belting layer 6 are the polyester belt lapping layer.The utility model employing density weaves the screen that forms greater than 90% copper wire or tinned copper wire, can reach good shield effectiveness; Adopt tinned copper conductor, improved conductance; Adopt the composite material of silicon carbide packed layer, improved the intensity of product, adopt halogen-free and low-smoke flame-retardant polyolefin sheathed layer, improved the anti-flammability of product.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
