  • Typical conductor sizes between #2 and 1000 MCM (34 mm2 to 500 mm2)
  • Typical circuit lengths from a few hundred feet up to a max of 170,00 ft (52 km)

Developed to meet the requirements for typical medium-voltage distribution cable fault location markets from 11 to 35 kV system voltage, with typical end users including:

  • Operations department of power utility companies
  • Electrical departments within municipalities
  • Private network operators
  • High voltage electrical contractors
  • Service companies
  • Port authorities
  • Mining
  • Airports
