Abstract

In order to develop non-linear material used for the reinforced insulation in HVDC cable accessory, non-linear EPDM composites were fabricated by adding conductive nano fillers to improve the conductivity characteristic of EPDM. The conductivity and the DC breakdown strength of composites were tested under 25 oC and 70 oC, respectively. The influences of types, portions and compounds of nano inorganic fillers on the conductivity were researched and the results indicated that after adding proper portion of nano SiO2, the mechanical properties of EPDM were improved. Adding nano SiC, carbon black and graphite could make the nonlinear electrical conductivity better. Adding nano SiC, carbon black and graphite all could make a great influence on the breakdown strength of composite material.
