Abstract

The molecular structure is critical to the electrical performance of insulating material applied in HVDC cable system. According to free volume breakdown theory, the larger size and content of free volume cavity, the lower the breakdown field strength will be. The dielectric performance of insulating material is closely related to its free volume and it depends on the content of vinyl. In this paper, molecular dynamics simulation was used to construct different EPDM and analysis fractional free volume. The properties of EPDM with different content of vinyl also be researched, include mean square radius of rotation<S2> and mean square displacement (MSD).
