Characteristics of electrical conduction in glass transition point of XLPE

XLPE의 glass 전이점에서 전기전도 특성

Thermally stimulated current, cubical expension, capability change were measured by temperature variation. According to the capability change, TSC peak value was increased. We found that the crystal dissolution is 375 K and amorphous state becomes 388K. Charged partical behavior in the dipole and electronic trop were found iomic conduction in the low field and electronic conduction in the high field. Charged particle in the semiconduction storey was aceumulated in the interface by electron injection which can be arise TSC.
