Abstract
The utility model relates to a high-voltage multi-core shielded signal cable, which comprises a single-strand wire formed in a way that an FEP (fluorinated ethylene propylene) inner insulation layer and a PFA (tetrafluoroethylene perfluorinated alkey vinye copolymer) outer insulation layer are sequentially arranged outside a silver-plated copper wire core; two single-strand wires are articulated on a split-phrase shielding layer externally provided with a polyester aluminum composite thin film so as to form a double-strand shielding wire; four double-strand shielding wires, an aramid fiber reinforcing core, four polyethylene filling cores and a tinning copper ground wire are collected to form a cable, and then a polyester aluminum composite thin film inner shielding layer, an outer shielding layer formed by weaving a thinning copper wire and a polyurethane outer protective sheath are sequentially arranged. The utility model has the advantages that the shielded signal cable is high-voltage resistant and has good dielectric property, chemical resistance stability, heat stability and mechanical strength. The protective sheath adopts polyurethane, thereby having the characteristics of good softness, large tensile strength, good abrasion resistance, oil resistance and aging resistance and the like. The ground wire adopts the tinning copper wire; and the application of the tinning copper ground wire not only, good corrosion resistance and weldability of the ground wire can be ensured, and the anti-electromagnetic interference capacity of a system can be improved.
Description
Technical field
The utility model relates to a kind of composite cable, particularly a kind ofly is suitable between power supply and the equipment transmission of long-range data signal and electric energy is provided, and possesses the high pressure multicore shielding signal cable of the function of haulage gear simultaneously.
Background technology
Existing common signal shielding cable does not generally possess high pressure resistant and drag function, and anti-outside electromagnetic interference ability, thereby is unfavorable for long range signals transmission and power delivery.Power line adopts the stranded insulation form that extrudes again in the general in addition composite cable, the whole cable external diameter is increased and rounding not.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of and has that proof voltage height, anti-outside electromagnetic interference ability are strong, soft, the high pressure multicore shielding signal cable of characteristics such as tensile strength is big, wear-resisting, oil resistant, resistance to ag(e)ing.
The utility model for achieving the above object, the technical scheme that is adopted is: a kind of high pressure multicore shielding signal cable, it is characterized in that: be included in the silver-plated copper wire stylet and be provided with one deck perfluoroethylene third rare inner insulating layer outward successively, the single cord that tetrafluoroethene-perfluoroalkyl vinyl ether copolymer external insulation layer constitutes, two single cord pair twists are provided with one deck polyester aluminium laminated film sub-shield and constitute bifilar shielding conductor outside it, four bifilar shielding conductors, an aramid fiber strengthening core, four polyethylene filled cores, behind the tin-coated copper ground wire set stranding, be provided with one deck polyester aluminium laminated film internal shield more successively, the outer shielding layer of one deck tinned wird braiding, one deck polyurethane oversheath.
Characteristics of the present utility model are: high pressure multicore shielding signal cable is the multicore shielding signal cable of a kind of high voltage withstanding 15kV, and conductor thread core is the low silver-plated copper conductor of resistivity, to guarantee the electrical property of conductor.Inner insulating layer is a perfluoroethylene-propylene, has not only guaranteed the cable excellent electric insulation, and has excellent chemical-resistant stability, thermal stability and mechanical strength.External insulation layer is tetrafluoroethene-perfluoroalkyl vinyl ether copolymer, has not only guaranteed the electrical insulating property of cable, and has excellent dielectricity, chemical-resistant stability, thermal stability and mechanical strength.Double-insulated design makes this product have extraordinary electrical insulating property.Divide shielding to adopt polyester aluminium laminated film, can play a protective role, can play shielding action again, and adopt around-packing technology, reduced external diameter signal shielding cable.Strengthening core adopts the aramid fiber that pulling force is very big, density is minimum, has both guaranteed the requirement of tensile strength, has in light weight, rub resistance simultaneously again, flexibility is good.Filled core adopts low density polyethylene, and the interpolation of filled core makes the construction of cable stable.Polyester aluminium laminated film is adopted in inner shield, to guarantee the rounding property requirement of cable, plays the effect of shielding and isolation simultaneously again, and adopts around-packing technology to make cable soft and compact more.The tinned wird braid shielded is adopted in external shield, high count has strengthened the anti-outside electromagnetic interference ability of cable, processing technology adopts the multiply type of weave not only to increase flexibility, and has reduced external diameter, and the application of tinned wird makes shielding have good corrosion and solderability.Sheath has adopted polyurethane, characteristics such as softness, tensile strength are big, wear-resisting, oil resistant, resistance to ag(e)ing that it has.Ground wire adopts tinned wird, and the application of tin-coated copper ground wire not only makes ground wire have good corrosion and solderability, and has improved the ability of the anti-electromagnetic interference of system.
