General information about ADCF-3000L Cable fault location:
1- Introduction
1 It is a one body trolley structure, easy handling at site.
2 You can do site test without complex wiring, because all test modes and switching voltage levels are automatically switched by weak control internal high-voltage switches.
3 It can quickly locate and point low resistance, high impedance fault leakage, flashover faults in power cable with a variety of 220V-220KV voltage level.
2- Characteristics
1 It integrates multi-gear DC high-voltage generator, multi-gear high-voltage capacitor, arc-stabling units and a variety of signal acquisition in one body, which facilitates fault location operation.
2 Switching between three gear test modes, two gear voltage levels is controlled by low-voltage weak electricity.
3 World’s leading test method makes difficult fault detecting become very simple.
4 The requirement to operators’ level for technical equipment is low.
5 The DC voltage is up to 32kV.
6 Each stall of voltages, which is 16 / 32kV, can output up to 1536 J impact energy. It has longer ranging delay arc time and makes a loud voice on the fault point when locating.
7 It can do high impedance fault detection directly without burning.
6 Large wheels ensure a smooth, easy handling and site work.
