Thermocouple and controlling cables of electric penetrations for nuclear power stations. hermetization with glass-ceramic and glass-fiber materials

New perspective technology for hermetization of cable ends for fabrication of hermetical inlets for NPPs with inorganic materials is developed. On the basis of the studies dielectric inorganic materials, resistive to γ-radiation and fire, are selected for creation of hermetically sealed inlets. Principally new methods for fabrication of hermoinlets is developed on the basis of metallic modules with fibre circuitously and ceramic hermetization units
