Product Features
l Three built-in capacitance gears are suitable for testing various main insulation faults of power cables with different voltage levels.
l Fast voltage boosting speed and high power save time and reduce labor costs.
l The touch screen control system of the power frequency high-voltage power supply unit reflects human-computer interaction, with convenient operation and simple and intuitive display.
l The system is equipped with a 25m test line, which is convenient for cable fault testing in long-distance, short-distance and complex environments.
l The whole machine is designed according to European standards and is equipped with a permission key for professional use.
l The whole machine has a grounding loop and step voltage monitoring protection system to protect the safety of equipment and personnel in real time.
l It has an emergency stop button and automatic discharge function. When emergency stop or shutdown occurs, it will automatically step down and discharge, which is safe and reliable.
l The output high voltage has single-pulse and continuous-pulse functions, which are respectively used with the fully intelligent multiple-pulse cable fault tester and precise locator to find fault points.
