CBC-50С (CBC-100C)


Automatic CBC-C series systems are designedfor high-voltage withstand testing of electrical protective equipment and insulated hand tools.

The testing is carried out with an AC voltage up to 50 kVRMS (up to 100 kVRMS for CBC-100C) at industrial frequency (f = 50 Hz).


CBC-C-series systems are supplied with a range of holders allowing to test a wide range of objects, including:

✓ rubber insulating gloves and dielectric safety boots;

✓ hand tools with electrical insulation;

✓ voltage indicators;

✓ discharge rods;

✓ insulating mats.


CBC-C-series systems are able to operate in a fully automatic mode – apply, stabilise and control the output voltage according to the pre-set parameters, as well as fill and drain the test bath using electric pump as part of the test cycle.


  • The CBC-C-series testers have five pre-set output voltage levels, as well as one user-defined one.
  • Test duration is set and monitored via a built-in timer.
  • Leakage current is displayed throughout the entire test cycle.
  • Upon detecting a breakdown, the system indicates the specific glove the breakdown has occurred in and automatically terminates the test.


The system comprises of control, high-voltage and measurement units, as well as a separate test bath. Such multi-module design allows an operator to remain at a safe distance away from high-voltage circuit and the test bath.


CBC systems of C-series include the following operational safety measures:

✓ Overcurrent protection.

✓ Short-circuiter on the high-voltage outlet.

✓ Protective earthing.

✓ Fuses.

✓ Sulphur hexafluoride gas pressure monitoring in the high-voltage unit (units).

✓ Emergency stop button.
