Abstract

The installation quality becomes the main reason causing the insulation failure of mid-voltage cable accessories. In this paper, based on the problem analysis during the installation process, a new installation technology of mid-voltage cable accessories by using RTV silicone rubber adhesive was put forward to eliminate the insulation defects in the conventional installation process. By constructing the insulation testing system, the withstand voltage test, partial discharge check, water-resistant test, surface flashover test and bonding pressure test were conducted to verify the feasibility and safety of the proposed installation method. The test results showed that the proposed method can enhance the operation reliability of mid-voltage cable joints and reduce the technical difficulty of on-site installation.
