Appointment

BZKP reduces the amplitude values and the natural frequency of the transition process to a level ensuring the absence of re-ignition. Protection works with all kinds of switching. Block parameters are calculated using specially developed software.

Technical effect:

  • surges are reduced to an acceptable level;
  • longer service life of the protected equipment.

Advantages

The monolithic body of BZKP can increase the strength and reliability of the design. The body is made of a material posessing following characteristics:
