Insulating rubber kraal pad withstand voltage method

by:Desing      2020-04-07
Insulating rubber kraal mat voltage resistance test method: each insulation voltage resistance test is plastic board are required. Inspection method is to put insulation rubber kraal pad covered by metal plate ( Generally available aluminum plate) Framework and, on each side of the insulation rubber kraal pad on a less than 10 cm metal board, insulating board again placed on the metal plate connected to the transformer a electrode, the other one electrode in insulating rubber kraal pad the other side, and then at the rate of about 1000 v/s to test voltage, last 1 min and record milliampere meter on the indicated value. No breakdown for qualified products. Inspection when the high voltage breakdown of the insulation rubber kraal pad, at hole repair is allowed, but must be resistant to voltage test after repair, eligible talents to use, and only for a second.
