Mineral Insulated Signal Transmission Cable for Nuclear Reactor is used for medium and high frequency signal transmission in reactor core instrumentation system. It is with a single core coaxial structure. According to different requirements for anti-interference performance of signal transmission, it has three structures: coaxial, double shield and triax
——Mineral insulated coaxial cable: composed of conductor, mineral powder insulation and metal sheath from inside to outside;
——Mineral insulated double shielded cable: it is composed of conductor, inner insulating layer of mineral powder, inner shielding layer, outer insulating layer of mineral powder and metal sheath from inside to outside;
——Mineral insulated triaxial cable: it is composed of conductor, mineral powder inner insulation layer, inner shielding layer, mineral powder outer insulation layer, outer shielding layer and metal sheath from inside to outside.
The components are as follows:
——Conductor: copper, nickel chromium alloy or pure nickel
——Internal / external insulation: high purity magnesia powder (MgO), alumina powder (Al2O3) or silica powder (SiO2);
