“A colleague recommended Cable Pro as a cost effective and valuable tool for cabling sizing so I purchased the online (Web) version recently. As a professional engineer, I find Cable Pro to be efficient, easy to use and accurate. Whenever I have spoken to the team at Electrotechnik they have been extremely responsive, helpful and open to new ideas. I am keen to see what additional features and improvements are made and I am glad to have Cable Pro in my toolbag.”

“UGL purchased 4 off Cable Pro Web licenses to allow several electrical power engineers to check their calculations. We have found the availability of the software excellent to perform the checks we require. The web based version ensures our calculations are current and based on the latest version of Cable Pro. All in all we are more than happy with the process.”
