"GB/T 3333-1999 cable paper power frequency breakdown voltage test method" stipulates the test method of cable paper power frequency breakdown voltage. The standard specifies the test principle, equipment, sample preparation and test process, and the voltage value of the cable paper when it is broken down is observed by step-up voltage, and its electric strength is accurately measured. It provides a unified specification and scientific basis for evaluating the insulation performance of cable paper and ensuring product mass and safety.
