Comparison of cable ageing
Original language description
Two cable types, which currently are used in nuclear power plants (NPP) and which are composed by jacket/insulation materials, i.e. PVC/PVC and PVC/PE, were exposed to accelerated ageing conditions, in order to simulate their behaviour after 10 years inservice. The cables were aged under two different test conditions:a) with relative high accelerating ageing speed:Radiation ageing was canied out at room temperature at a dose rate of 2900 Gy/h, folio wed by thermal ageing at 100 °C. This accelerated ageing condition was fairly fast, but still in compliance with the standards.b) with moderate ageing speed:The radiation and thermal ageing was performed simultaneously (superimposed) at a dose rate of 2.7 to 3.7 Gy/h and a temperature of 68 to 70 °C.
