The STX40 redefines the state-of-the-art: as a complete package, it comes with all necessary fault-locating components fully integrated in a single robust housing. With its single rotatory knob or touch screen control and its fully automated motorized HV switches, the STX 40 is the most convenient and most powerful portable fault location unit on the market. It is ideally suited for all essential fault-locating tasks, such as analyzing, prelocating, and pinpointing faults on low-voltage and medium-voltage XLPE or EPR insulated cables. With its 40 kV DC source and a potent high-frequency burner, it is also highly effective on PILC cables.
