    Abstract: In order to solve the problem unable to carry out secure connection tests caused by indoor cable terminal test lead channel tension, this paper design a set of high voltage cable test wire erection device used for inside cable terminal of indoor transformer substation with windows to carry out high voltage cable alternating current (AC) voltage withstand test. This device adopted the design scheme based on insulated isolation tubal. The module was designed in four parts including cable core conductor, insulating material, insulating surface structure and adjustable support. After the application of field verification of AC voltage withstand tests in multi-110 kV cable circuits, there is no tension for the indoor cable on the terminal voltage test of substation leads channel. The tested terminal realizes the safety connection with the testing equipment.
