A tester for measuring insulating properties of cross-linked polyethylene, the tester including: a housing including a control panel; a high voltage chamber including an insulating cover, a fixed frame, an insulating oil cup, a high voltage electrode, a ground electrode, and a temperature control device; and a test circuit including a high voltage power supply, a voltmeter, a timer, an overcurrent protection device, and a digital thermometer. The high voltage chamber and the test circuit are arranged inside the housing. The control panel is arranged on the housing. The insulating cover is disposed on the high voltage chamber. The fixed frame is disposed inside the high voltage chamber. The insulating oil cup is mounted on the fixed frame. The high voltage electrode and the ground electrode are disposed oppositely inside the insulating oil cup. The temperature control device is disposed beneath the insulating oil cup. |
