The rated voltage value of the pillar insulator is selected according to the maximum voltage value of the equipment specified in GB156. The power frequency breakdown voltage is only conducted on type B insulators with a rated voltage of 40.5KV and below. The power frequency and operating shock humidity withstand test is only conducted outdoors. Insulators are carried out. *The moisture tolerance value of this voltage level should be agreed between the supplier and the buyer. |
