Test Methods for Dielectric Strength Testing of Insulating Boots and Insulating Materials
Dare Electric recommends
NYZ series insulating boots (gloves) withstand voltage device adopts advanced microelectronic processing technology, all processes can be set in advance, full Chinese interface, simple and clear operation. After all test items are set, the test is automatically carried out without manual intervention. The insulating boots withstand voltage device is special equipment for batch testing of insulating boots and gloves, and can also be used for withstand voltage testing of safety tools such as insulating rods, insulating screwdrivers, insulating pads, etc.
When conducting water immersion test inside and outside the insulating boots (gloves), remove the partition plate and sponge. The water level inside and outside the insulating boots (gloves) should be the same height, with a 90mm portion exposed above the water surface, and ensure that the exposed part of the insulating boots (gloves) is dry and clean. Then place the high-voltage electrode inside the insulating boots (gloves) and clamp the insulating boots (gloves) properly.

When conducting steel ball test inside insulating boots, add water to the water tank up to the partition plate to fully soak the sponge. Place a metal piece consistent with the size of the tested boot inside the boot, put the high-voltage electrode into the insulating boot so that the high-voltage electrode contacts the metal piece, then cover the metal piece with metal balls with a diameter not greater than 4mm, and the height should not be less than 15mm.

First, keep the water level of the six electrodes 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 as far away from the water tank as possible. Other wiring methods are the same as for insulating boots (gloves).
