70kV Cable Fault Thumper



Catalog ID:


HIPOTRONICS' CF70 cable fault locator is designed for simple location of medium and high voltage primary cables faults. In addition to the high energy capacitive discharge feature, this product allows users to perform a high voltage DC proof tester, and use a high current burner for high resistance faults.These self-contained, portable units are rugged and reliable making them ideal for years of field use. The CF70 has a continuously adjustable output for DC proof tests up to 70 kV, 100 mA of burn current and up to 25 kV and 3750J or 7000J of high energy capacitive discharge. This product can be easily combined with a time domain reflectometer (TDR 1150 / TDR 1170) via a high voltage coupler (HVC 4175).This combination of equipment can greatly reduce down time to find the fault, and reduce further damage or degradation to the cable under test.
