Certification and Compliance


Continuously validating Cableizer is a task we take serious. An extensive test suite ensures that simulation results are always accurate and reliable. Cableizer is continuously and automatically validating its simulation results against accredited values from publications and data sheets of cable suppliers. The following validation reports might be of special interest:

  • Comparison with Cymcap
  • Latest results of our validation test suite are published here
  • Cable pulling validation examples (Brugg, Southwire)

There is no possible certification for Cableizer because there exists no notified body or standardization company which can give an approval for cable rating software tools.

The Cigré workgroup B1.56 worked years on a guide regarding the verification of cable current ratings. According to the paper 'Overview of CIGRÉ WG B1.56 regarding the verification of cable current ratings' published 2019, a set of case studies will be provided and guidance points developed.
The Guide 880 'Power cable rating examples for calculation tool verification' was finally released mid-september 2022. We will add the Cigré case studies to our validation test suite and publish our compliance.

Cableizer is Software as a Service (SaaS), a cloud-based service where instead of downloading and installing software from your desktop PC or business network to run and update manually, you alternatively enter an application via an internet browser. No downloadable version exists and since access to calculation features depends on a paid subscription, we have no concerns about piracy of our software which might otherwise damage our pricing models. If you find a website you suspect may be selling or distributing a nonvalid Cableizer software or which provide illegal shared access to a Cableizer account please help us and others by reporting the seller/provider.
