Abstract

The invention relates to the technical field of cables, in particular to an anti-nuclear radiation semi-flexible coaxial signal transmission cable which can operate within the temperature range of minus100 DEG C to +150 DEG C for a long time, and has the radiation intensity more than 1*106Gy. The cable comprises an inner conductor, an insulating layer, an outer conductor and a jacket layer, is mainly used for transmitting and detecting an equipment operation signal in the nuclear island of a nuclear power station, and is also used for nuclear submarines. The anti-nuclear radiation semi-flexible / semi-rigid coaxial cable of the invention is prepared by extruding an injection molding material, namely polysulfone (PSU) plastic on the common fluorine plastic extrusion production line through a YJTB technique comprising the following steps: PSU material preprocessing, extrusion auxiliary device designing, extrusion process parameter matching and optimization design, process temperature gradient screening and controlling, cooling speed controlling and the like.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an anti-nuclear radiation (radiation resistance strength greater than 1x10 6 Gy), a semi-flexible coaxial signal transmission cable that can work in the temperature range of -100 to +150°C for a long time. Background technique [0002] With the rapid development of my country's nuclear power industry, the demand for the number and variety of cables used in nuclear reactors is increasing; in addition, the development of the military industry has also put forward higher requirements for anti-nuclear radiation cables. [0003] Nuclear island cables for nuclear power plants are installed in the containment to realize power transmission, operation control and signal detection of equipment in the nuclear island. Such cables are required to fully perform their specific functions in the special environment of normal operation of nuclear reactors, accident conditions or post-accident cond...
