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, resulting in heavy testing workloads. Therefore, such withstand voltage test devices are designed to be compact, lightweight, and portable, giving rise to the portable cable withstand voltage test system.
● 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, facilitating easy access to power on site.
● The reactor part adopts dry-type epoxy casting, which is aesthetically pleasing and reliable, suitable for various cable requirements.
