Abstract
The utility model relates to a cable, and especially relates to a novel mining steel tape armoured control cable with a shielding polyurethane sheath. The control cable comprises insulated cable cores, and each of the insulated cable cores is composed of a conductor and a low density polyethylene insulating layer which wraps the exterior of the conductor in an extruding manner. A plurality of insulated cable cores form the control cable. The exterior of the control cable is sequentially wound by a polyester wrapping tape layer, wrapped by a linear low density polyethylene inner sheath layer in the extruding manner, wrapped by a shielding layer in a weaving manner, wrapped by a polyvinyl chloride sheath layer in the extruding manner, armoured by a steel tape armoured layer, and wrapped by a polyurethane outer sheath layer in the extruding manner. The beneficial effects of the utility model comprise low temperature resistance, smaller external diameter, light weight, good mechanical property, good fire resistance, good softness, good shielding effect, and environmental protection.
Description
Technical field
The utility model relates to a kind of cable, a kind of steel tape armouring control cable of the polyurethane jacket with shielding that particularly New Coal Mine is used.
Background technology
Along with the develop rapidly of New Coal Mine and petroleum industry and defence engineering, cable is proposed to higher requirement, cable is to Composite, environmental protection, the fire-retardant future development such as low temperature resistant.At present polyvinyl chloride insulation, pvc sheath control cables are multiplex bribes and the occasions such as protection circuit in monitoring, the stationary applica-tions such as indoor, cable trough, pipeline are laid in more, but often can not bear larger mechanical external force, irremovable, the product external diameter is relatively large, weight ratio is heavier, and shield effectiveness is poor, can not meet the requirement of New Coal Mine; Pvc sheath is embedded in underground easy contaminated environment in addition.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of steel tape armouring control cable of the polyurethane jacket with shielding.Be applicable to ac rated voltage u0/u and be 450/750V and following control monitoring loop and protection circuit and distribution install in electrical instrumentation adjoin line.
The utility model for achieving the above object, the technical scheme of taking is: a kind of steel tape armouring control cable of the polyurethane jacket with shielding, it is characterized in that: be included in conductor and extrude the insulated wire cores that the colored low density polyethylene (LDPE) insulating barrier of one deck forms outward, belting layer, inner restrictive coating, screen, restrictive coating, the steel-tape armouring layer, external sheath layer, several described insulated wire cores strandings, be wound around successively one deck polyester belting layer outside it, extrude one deck LLDPE inner restrictive coating, braiding one deck screen, extrude one deck pvc sheath layer, armouring one deck steel-tape armouring layer, extrude one deck polyurethane external sheath layer.
The beneficial effects of the utility model are:
1, low temperature resistant: cable adopts three layers of sheath, and inner sheath adopts the LLDPE material, low temperature resistant reaching-60 ℃ when this kind of material is normal, and external sheath layer adopts the polyurethane material of weatherability, can be for the place of limit low temperature.
2, external diameter is little, lightweight: the thickness of insulating barrier is that 0.6mm, inner restrictive coating thickness also only have 1.5mm, and the density of LLDPE material is 0.926g/cm
3, and the density of the polythene material of common cable line is generally 1.43 g/cm
3, than the weight of common cable line, to reduce 40% left and right.
3, good mechanical property: the intensity of this kind of material of LLDPE is very high, has the very high anti-ability of cutting, and has greatly improved the mechanical performance of insulation, and this kind of Tensile strength on average can reach 26Mpa.Steel-tape armouring and polyurethane material in addition, the use of can bearing a heavy burden of this kind of cable.
4, good flame resistance: inner sheath adopts the oxygen index of this kind of material of LLDPE can reach 40, has very high fire resistance, and oversheath adopts polyurethane jacket, can be applied to complicated hot environment.
5, softness: because conductor has adopted the stranded formation of bare copper wire of 0.2mm, so greatly improved the flexibility of cable, cable is easy to laying installation.
6, shield effectiveness is good, uses 7 strands of 0.2mm proof copper-wire braideds as screen, pitch 45-46 millimeter, and density is not less than 80%, and shield effectiveness can reach more than 85%.
7, environmental protection, used polyurethane jacket, can be laid in for a long time underground, non-degradable and contaminated environment.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
