“…Power cable accessory is an important device to connect the cable with the transmission line and the transformer substation [1][2][3]. During the installation and operation of XLPE (Cross-Linked Polyethylene) cable, moisture in the environment can intrude into the insulation materials and interfaces of the cable body and the accessories, leading to the insulation decline or even the insulation breakdown of the cable [4][5][6]. As a result, it is of great signi cance for improving the stability of the cable line to fully understand the dampness properties of the cable accessory.…”

Moisture in the insulation of distribution cable accessories is one of the important causes of insulation degradation and discharge failure of the accessories. The changes in the insulation properties of EPDM (Ethylene-Propylene-Diene Monomer) and SIR (Silicone Rubber) with the time of dampness are studied, and the mechanism of dampness is revealed by combining the surface water absorption characteristics and functional group analysis. The results show that the hydrophobicity of EPDM specimens is lower than that of SIR, resulting in the electrical properties of EPDM being signi cantly lower than those of SIR after water immersion. The resistivity and the ashover voltage of both specimens decrease signi cantly with the increase of moisture exposure time, and the decrease of EPDM is more obvious than that of SIR.The breakdown voltage of EPDM decreases by 26.6% and that of SIR decreased by 13.06%. Besides, the ashover voltage along the surface of both EPDM and SIR decreases with the increase of water immersion time, and the decreasing trend of both of them is basically the same. This work has guiding signi cance for the material selection of the cable accessories and the analysis of damp failure.

Moisture in the insulation of distribution cable accessories is one of the important causes of insulation degradation and discharge failure of the accessories. The changes in the insulation properties of EPDM (Ethylene-Propylene-Diene Monomer) and SIR (Silicone Rubber) with the time of dampness are studied, and the mechanism of dampness is revealed by combining the surface water absorption characteristics and functional group analysis. The results show that the hydrophobicity of EPDM specimens is lower than that of SIR, resulting in the electrical properties of EPDM being significantly lower than those of SIR after water immersion. The resistivity and the flashover voltage of both specimens decrease significantly with the increase of moisture exposure time, and the decrease of EPDM is more obvious than that of SIR. The breakdown voltage of EPDM decreases by 26.6% and that of SIR decreased by 13.06%. Besides, the flashover voltage along the surface of both EPDM and SIR decreases with the increase of water immersion time, and the decreasing trend of both of them is basically the same. This work has guiding significance for the material selection of the cable accessories and the analysis of damp failure.
