Executive Standard: DL/T849.6-2004
Product Features of XGTF Series Cable Variable Frequency Series Resonance Withstand Voltage Test Device:
● Cables with voltage levels of 35kV and below are used in large quantities, and the testing workload is heavy. Therefore, this type of withstand voltage test device is small in size, light in weight, and the portable cable withstand voltage test system was thus born;
● This system requires that the weight of any component that can be moved by a single person on site does not exceed 30kg, making it suitable for on-site handling;
● The power supply uses 220V single-phase or 380V single-phase, convenient for on-site power access;
● The reactor part adopts dry-type epoxy casting, which is beautiful and reliable, suitable for various cable requirements.
