Abstract :
We studied the electrical, chemical and mechanical characteristics of XLPE by dicumyl peroxide (DCP) and trimethylolpropane triacrylate (TMPTA) content ratio. DCP content was changed from 1.0 to 2.5 phr increasing 0.5 phr. TMPTA content was changed 0.5 to 1.5 phr increasing 0.5 phr. Thermal analysis (DSC) was carried out in order to observe the tendency of Tg according to DCP and TMPTA content. Tensile strength was measured in order to observe the mechanical strength. In experimental results, DCP content of 2.0 phr and TMPTA content of 1.0 phr has the highest breakdown strength. A DCP content of 2.0 phr and TMPTA content of 0.5 phr has lowest dielectric constant. The tendency of Tg was not affected by DCP and TMPTA content
