Products Description
Introduction to the Ultra Low Frequency Voltage Withstand Test Procedure (Q/ED116501-2004 Rubber Plastic Power Cable Handover and Preventive Test Procedure)
Ultra low frequency is mainly used in the AC voltage withstand test of cables within 35kV. The test voltage and test time for different specifications of cables are determined according to relevant regulations, and the content of these regulations is basically the same at home and abroad. Below is a summary of the main content of the "Q/ED116501-2004 Rubber Plastic Power Cable Crossing and Preventive Test Regulations", which is for user reference:
1 Test time 60 minutes
