Abstract

Abstract: The crosslinked polyethylene (XPLE) insulation materials for HVAC cables are developed relatively late in China. At present, the domestic-made insulation materials for 220 kV voltage grade have not been applied in practical engineering. Based on three types of domestic and foreign made XPLE insulation materials used for HVAC cables, a comparative experimental study is made on their power frequency breakdown strength, dielectric constant, dielectric loss tangent, melting and crystallization properties, tensile properties, elongation at break, micro-morphology and crosslinking degree. The experimental results show that the domestic made XLPE insulation materials are not much different from imported ones in macro performance parameters, with the domestic-made insulation material samples even being better than the imported X1# samples in breakdown characteristics and mechanical properties. However, some shortcomings are also found for domestic-made insulation materials, such as poor stability of breakdown strength and large value of dielectric loss tangent. The results of this study can provide a data support for the development and performance improvement of domestic-made cable insulation materials.

Key words: high voltage cable, crosslinked polyethylene, insulation performance
