Insulating rubber kraal stall withstand voltage test methods of insulation rubber MATS voltage resistance test method: each insulating rubber voltage resistance test is byre pad are required. Testing method is put insulating 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, another electrode in insulating rubber kraal pad on 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 to be used, and only for a second.
