Research on the electric field intensity distribution of high-voltage cable terminal improved by non-linear material

The electric field distortion caused by the high voltage current environment in cable terminal will greatly increase failure probability and reduce operation safety; therefore, it is necessary to ensure uniform distribution of terminal. This paper briefly introduced high-voltage non-linear materials. traditional silicone rubber added with nano-SiO 2 were prepared. electrical conductivity two rubbers was tested, simulated. results demonstrated that improved had a higher less affected temperature. calculation simulation model also showed internal strength more uniform, maximum on reinforced insulation smaller after used as insulation.
