Abstract: In order to achieve high quality electrical materials for cable terminations, the crosslinked ethylene-propylene-diene monomer (EPDM) materials, with adequate breakdown strength, appropriately increased conductivity and are developed by employing auxiliary crosslinker and ultraviolet (UV) photoinitiated crosslinking technique. The characteristic cyclic anhydrides with coupled carbonyl groups are utilized as auxiliary crosslinkers to promote crosslinking efficiency and provide polar-groups to EPDM molecules in … Show more

“…Not many reports on DC conductivity measurements using reasonable charging time are available in the literature for EPDM. A quasi field-independent conductivity of EPDM for fields up to 10 to 20 kV/mm was reported, contrasting with the strong field dependence of conductivity of XLPE [31]. Besides, EPDM is a complex material, and its behavior may change with compounding: D. Li et al [32] found power law relation between conductivity and field with an exponent in the range from 0.2 to 0.9, depending on EPDM grade (with using only 1 min charging time!…”

Li et al [16] reported on quasi field-independent conductivity of EPDM for fields up to 10 to 20 kV/mm that contrasted with the strong field dependence of conductivity of XLPE.

“…Ethylene-propylene-diene monomer (EPDM), one of the most commonly used rubbers, has been widely used in low/medium voltage, high voltage and even ultra-high voltage cables due to the excellent electrical insulation, good ozone resistance, moisture resistance, heat resistance, cold resistance and other properties [ 1 , 2 , 3 , 4 , 5 ]. However, EPDM is still prone to aging under the combined action of heat, oxygen, light and other conditions, resulting in a significant decline in performance [ 6 , 7 , 8 ].…”
