Abstract
The utility model discloses an instrument control cable resisting ultra-low temperature and high voltage. The instrument control cable resisting ultra-low temperature and high voltage is composed of a cable core and an XLPE sheath. A first polyimide belting layer wrapping the cable core, a tinned copper conductor weaving layer, a second polyimide belting layer, an XLPE high voltage insulation layer, a third polyimide belting layer and a tinned copper conductor weaving layer are arranged between the cable core and the sheath successively from inside out. The instrument control cable resisting ultra-low temperature and high voltage provided by the utility model has characteristics of resisting high voltage, resisting radiation and having low gas efficiency.
Description
Technical field
The utility model relates to a kind of electric wire field for superconduction control, is specifically related to the instrumentation control cable of a kind of super low-temperature resistant, high pressure.
Background technology
International ITER organizes and researches and develops follow-on fusion reactor, need use a kind of super magnet system in the reactor to the same strong magnetic confinement in reactor ground, need very large energy input, common cable arrives the not demand of transmission capacity, should this adopt low-temperature superconducting to super magnet power supply, what low-temperature superconducting adopted be the liquid helium cooling, and variations in temperature easily makes the superconduction quench, accidents caused, therefore need the temperature of monitor closely superconduction cooling system and the voltage in the superconduction.The instrument control cable that traditional monitoring temperature and voltage are used can't satisfy following requirement: 1. low temperature resistant-269 ℃; 2. high pressure resistant 56kV; 3. radiation hardness (100kGy); 4. gas efficiency is little by (10

-1); 5. the outside diameter of cable is no more than 12.5mm.
The utility model content
The utility model purpose: the purpose of this utility model is in order to remedy the deficiencies in the prior art, the instrumentation control cable of a kind of anti-ultralow temperature, high temperature to be provided.
Technical scheme: the instrumentation control cable of a kind of anti-ultralow temperature, high pressure, formed by cable core and XLPE sheath, be provided with successively from inside to outside the first polyimides belting layer that is wrapped in cable core between described cable core and the sheath, the tinned copper conductor braid, the second polyimides belting layer, the XLPE high-voltage insulation layer, the 3rd polyimides belting layer, tinned copper conductor braid.
Described cable core comprises that some twisted wires and aramid fiber extrude the polyimides filler, described twisted wire outer wrapping the 4th polyimides belting layer, every twisted wire is formed by a pair of silver-plated copper wire stranding, described silver-plated copper wire outer wrapping polyimide insulative layer, and described aramid fiber extrudes the polyimides filler and is arranged on gap between adjacent two twisted wires.
Beneficial effect: the utility model has adopted after such structure, and product insulation also has the ability of anti--269 ℃ of low temperature, has simultaneously high pressure resistant, radiation hardness and the little characteristics of gas efficiency.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
Embodiment
The instrumentation control cable of a kind of anti-ultralow temperature, high pressure, formed by cable core and XLPE sheath 1, be provided with successively from inside to outside the first polyimides belting layer 2 that is wrapped in cable core between cable core and the sheath 1, tinned copper conductor layer 3, the second polyimides belting layer 4, XLPE high-voltage insulation layer 5, the three polyimides belting layers 6, tinned copper conductor braid 7.Cable core comprises that some twisted wires and aramid fiber extrude polyimides filler 8, the twisted wire outer wrapping the 4th polyimides belting layer 9, every twisted wire is by a pair of silver-plated copper wire 10 stranded forming, silver-plated copper wire 10 outer wrapping polyimide insulative layer 11, and aramid fiber extrudes polyimides filler 8 and is arranged on gap between adjacent two twisted wires.Silver-plated copper conductor: current circuit mainly is provided, polyimide insulative: the electric insulation that the loop is provided, the resistance to low temperature of material and radiation resistance are excellent, it is low temperature resistant and formant radiation, filler (optional): aramid fiber extrudes polyimides and fills, and mainly improves the tensile property of cable.The 4th polyimides band: tie up insulation core wire.The first polyimides band: tie up insulated wire pair.Tincopper fuse wire braided armor: shield electromagnetic is disturbed, the 3rd polyimides band: the protection high-voltage insulation layer provides excellent High-Voltage Insulation performance.Extrude high-voltage insulation layer: the High-Voltage Insulation protection is provided, adopts the mode of cross-linking radiation, improve the radiation resistance of cable.The polyimides band: the protection high-voltage insulation layer provides excellent High-Voltage Insulation performance.The tinned copper wire braiding: shield electromagnetic is disturbed, and extrudes the XLPE sheath, and protection cable internal structure has excellent resistance to low temperature, has sealing function, adopts the mode of cross-linking radiation, improves the radiation resistance of cable.
