Testing & Development Centre

Our laboratories at PRAKAB specialise primarily on the communication, installation and power cables up to 1kV, however, we are almost fully equipped for research and testing of most cable types.

Our analysis and research facilities are also available for your products or research projects. Several of our testing devices are accredited. 

It would be our pleasure to assist you with quality control on all levels, from the common input control up to the more challenging type tests.

Please do not hesitate to contact us for all your research and testing needs.
