BDT.500 Withstand Voltage Burn Down Cable Tester

The BDT.500 is a powerful, portable high-voltage burn down and DC withstand tester designed for use on low- and medium-voltage power and control cables. It delivers up to 60 kV DC and 600 mA burn current, allowing it to quickly burn through high-resistance and intermittent faults, converting them into low-resistance or dead-short conditions for easier pinpointing. In addition, it is ideal for DC withstand voltage testing of HV cables and other HV electrical equipment.

Key Features

  • Burn-through voltage: Up to 60 kV

  • Burn-through current: Up to 600 mA

  • High output power (2000 W) for effective conversion of high-impedance faults

  • Supports DC withstand testing up to 60 kV for cables and HV equipment

  • Converts intermittent or moisture-related faults into stable low-impedance conditions

  • Shockproof enclosure for safe operation

  • Automatic discharge of test object after shutdown or power failure

  • Rugged, portable design (29 kg) for field deployment

  • Acts as a reliable current source for cable fault location and insulation testing
