Research on Properties of Crosslinkable Polymer-Based Semi-Conductive Shielding Composites

Article Preview

Abstract:

In order to select effective carbon black (CB) and matrix resin for fabricating semi-conductive shielding materials of XLPE insulated high voltage cable, the crosslinkable composites were prepared by melt blending different types of CB with three types of copolymer resin, and the crosslinking samples were compressed. The electrical conductivity, mechanical properties, thermal elongation properties and rheological properties of the crosslinkable semi-conductive composites were measured. The research results indicated that compared to EVA-based and EEA1-based composites, the EEA2-based composites have the lowest volume resistivity and the best rheological properties, and the CB content has less effect on their mechanical properties. The properties of the composites with CB1 were superior to that of the composites with CB2. The composites prepared with CB1 and EEA2 present the best overall properties. These composites are expected to be used in the manufacture of semi-conductive shielding layer for high voltage cable.
