Features and Benefits

The CDS-3616U(F) is ideal for network systems or other fault locating scenarios where cables rated up to 69 kV, oil-insulated cables, and/or long cable lengths prevail. The powerful 1600 joule pulse makes fault location easier using acoustical and electromagnetic detection devices. With 280 mA of burn current, faults can be rapidly reduced to low voltage levels, permitting thumping at lower and less damaging voltage levels. The CDS-3616U can thump at 9 kV, 18 kV, or 36 kV while delivering 1600 joules.
