Test Methods for Withstand Voltage Test of Insulating Boots and Insulating Materials


Dari Electric recommends

The NYZ series insulating boots (gloves) withstand voltage device adopts advanced microelectronics processing technology. The entire process can be set in advance, with a full Chinese interface, making operation simple and clear. After all test items are set, the test is automatically conducted without manual intervention. The insulating boots withstand voltage device is special equipment for batch testing of insulating boots, gloves, and can also be used for withstand voltage testing of safety tools such as insulating rods, insulating screwdrivers, and insulating pads.



Tools/Raw Materials




  • Insulating boots (gloves) withstand voltage device, operation console, and insulating cylinder bracket

  • Insulating boots, insulating gloves, insulating rods and other materials, water, sanitary cotton cloth



Methods/Steps




  1. 1

    When conducting the water test inside and outside the insulating boots (gloves), remove the partition board and sponge. The water inside and outside the insulating boots (gloves) should be at the same height, with a 90mm portion above the water surface. Ensure the part of the insulating boots (gloves) above the water is dry and clean. Then place the high-voltage electrode inside the insulating boots (gloves) and clamp the insulating boots (gloves) properly.



  2. 2

    For the steel ball test inside the insulating boots, add water to the water tank up to the partition board to fully soak the sponge. Place a metal sheet matching the boot size into the boot, put the high-voltage electrode inside the insulating boot so that the high-voltage electrode contacts the metal sheet, then cover the metal sheet with metal balls with a diameter not greater than 4mm, to a height of not less than 15mm.



  3. 3

    First, ensure the water surface of the six electrodes is at least 375px. Then connect the high voltage from the water tank to one end of the insulator, and connect the other end to any one of the water tank electrodes (1~6). At this time, there is high voltage around the water tank. When connecting the electrode signal wires, keep them as far away from the water tank as possible. Other wiring methods are the same as for insulating boots (gloves).



  4. 4

    Before the test, first securely install and fix the high-voltage wire marked (high voltage danger) to the connection hole at one end of the water tank, and only then can the test be conducted.



  5. 5

    Set up the site according to relevant regulations, connect the equipment wiring. In areas where conditions permit, there should be dedicated safety personnel on site for guidance.
