Fig. 5From: Experimental investigation of E-beam effect on the electric field distribution in cross-linked polyethylene/ZnO nanocomposites for medium-voltage cables simulated by COMSOL MultiphysicsFrequency dependence of alternating current (AC) conductivity for zinc oxide (ZnO) nanoparticle-filled (i.e., 0, 1, 3, and5%) cross-linked polyethylene at 0 kGy (a) and 25 kGy (b). The AC conductivity increases as the frequency increases due to the effects of the electron beam dose (25 kGy)Back to article page
