Abstract
The invention discloses an ultralow-temperature-resistant and high-voltage-resistant instrument control cable, which consists of a cable core and a cross linked polyethylene (XLPE) sheath, wherein a first polyimide lapping layer coated with the cable core, a tinning copper conductor braid layer, a second polyimide lapping layer, an XLPE high-voltage insulating layer, a third polyimide lapping layer and the tinning copper conductor braid layer are sequentially arranged between the cable core and the sheath from interior to exterior. The instrument control cable has the characteristics of high voltage resistance, radiation resistance and low gas efficiency.
Description
Technical field
The present invention relates to a kind of electric wire field that is used for superconduction control, be 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 and give reactor ground with strong magnetic confinement, needs very large energy input; Common cable arrives the not demand of transmission capacity; Should this adopt low-temperature superconducting to give super magnet power supply, what low-temperature superconducting adopted be the liquid helium cooling, and variations in temperature makes the superconduction quench easily; Accidents caused, so 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.
Summary of the invention
Goal of the invention: the objective of the invention is provides the instrumentation control cable of a kind of anti-ultralow temperature, high temperature in order to remedy the deficiency of prior art.
Technical scheme: the instrumentation control cable of a kind of anti-ultralow temperature, high pressure; Form by cable core and XLPE sheath, be provided with the first polyimides belting layer that is wrapped in cable core between described cable core and the sheath from inside to outside successively, tin-coated copper conductor braid; The second polyimides belting layer; The XLPE high-voltage insulation layer, the 3rd polyimides belting layer, tin-coated copper conductor braid.
Described cable core comprises that some twisted wires and aramid fiber extrude the polyimides filler; Described twisted wire outerwrap the 4th polyimides belting layer; Every twisted wire is by stranded the forming of a pair of silver-plated copper lead; Described silver-plated copper lead outerwrap polyimide insulative layer, and described aramid fiber extrudes the polyimides filler and is arranged on the gap between adjacent two twisted wires.
Beneficial effect: the present invention has adopted after such structure, and product insulation also has the ability of anti--269 ℃ of low temperature, has high pressure resistant, radiation hardness and the little characteristics of gas efficiency simultaneously.
