Executive Standard: DL/T849.6-2004
XGTF Series Cable Variable Frequency Series Resonance Withstand Voltage Device Product Features:
● 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 testing device is small in size, light in weight, and portable, giving rise to the portable cable withstand voltage testing system.
● This system requires that the weight of any single component that can be moved on site by one person 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 aesthetically pleasing and reliable, suitable for various cable requirements.
