3 Terms and definitions

The terms and definitions defined in GB/T 17737.1-2013 apply to this document.

4 dielectric withstand voltage test

4.1 Principle The purpose of this test is to determine the withstand voltage of the dielectric under AC or DC conditions. 4.2 Test Equipment Test equipment includes. --- AC or DC power. ---KVolt meter. The frequency of AC voltage should be 40Hz~60Hz, and the waveform should be sine wave. 4.3 sample preparation The test shall be performed on finished cables that have passed the continuity test. Both ends of the cable should be stripped of conductors of sufficient length to avoid breakdown or failure Discharge. The insulation on the stripped conductors at both ends should be cleaned. 4.4 Procedures The insulation between the inner and outer conductors of the cable or between the conductors shall withstand an ac or dc voltage of 1 min. The voltage value should comply with the relevant sectional specification Or detailed specifications. The voltage boost rate of the test voltage should not exceed 2 kV/s. ......
