Nowadays, Low density polyethylene (LDPE) is increasingly used as voltage cable insulating material. Owing to its excellent mechanical and electri-cal properties, LDPE may undergo degradation under service conditions. The ...

Low density polyethylene (LDPE) is a usual material used within high voltage insulation systems. Like all polymers, this material may be aged after working under high voltage for a long time. The ageing process of this ...
