Abstract
The accelerated thermal aging of CSPE(chloro sulfonate polyethylene) of test cables were carried out for the period equal to 20, 40, 60, 80 and 100 years in air at 100, 110 and 120□, respectively. The CSPE cables (TAIHAN electric wire Co. Ltd) were used as starting materials. Condition monitoring methods of the accelerated thermal aging of CSPE cables were estimated through EAB (elongation at break) of IEC 62582, and those were newly estimated through volume electrical resistivity. A validated estimation of the new condition monitoring method of the accelerated thermal aging of CSPE cables was conducted by EAB, apparent density, FE-SEM(field emission scanning electron microscope), XPS(x-ray photoelectron spectroscopy) and WD-XRF (wavelength dispersive x-ray fluorescence). The activation energy of NPPs cable is calculated by σ = σ·e-Ea/RT formula through volume electrical resistivity. It is considered that life-time of CSPE cable can be predicted through volume electrical resistivity if CSPE jacket was aged for period such as more than 100 years.
