Abstract

Polyethylene (PE) has been widely used as electrical insulation for power cables because of its excellent electrical and mechanical properties. Low density PE (LDPE) prepared using a high pressure process has been widely used as insulating polymer of power cables. In this paper, the authors have investigated the performance of new LDPE prepared using metallocene catalyst (m-LDPE) as electrical insulating material. m-LDPE has narrower composition and molecular-weight distributions than LDPE. High-field electrical properties of m-LDPE at 90°C were compared with those of the other LDPEs. In addition, the prestress effect and the effect of space charge on breakdown strength were discussed
