The Online Cable Optimizer

What is Cableizer?

Cableizer is a software package for the design of power cable systems using electrical, mechanical, thermal and environmental calculations.

Cableizer is completely web-based because we believe SaaS is the future: It is cost effective, accessible anywhere, easily customisable, has improved interoperability, offers easier installation and maintenance, and offers tighter security than desktop applications.

  • We started in June 2015 and are developing heavily.
  • We offer monthly subscriptions for a fair price.
  • We are a small team working in the cable business for years.


  • Software guided design of cables up to 500 kV!
  • Cable calculations including mass, heat of combustion, CO2, price, etc.
  • System calculations of current rating and cable pulling
  • Environmental calculations incl. magnetic fields and soil temperature rise
  • Web-based without any installation or dongle but with automatic updates
  • Work together directly with customers and suppliers using share links
  • Support from engineers with many years of practical experience

Validation of calculation method for deeply buried objects (2021-05-03)
Based on the example of a deeply buried tunnel, the effect of the deep burial thermal inertia advanced option on the cable ampacity is illustrated and validated.

Cable crossing - Influence of spacing between systems and its limitations (2021-04-26)
Based on an example, the influence of the spacing between crossing systems on the cable rating is discussed and the limitations of the calculation method are outlined.

Ampacity calculations for deeply buried objects (2021-04-18)
When simulating objects that are buried deeper than a couple of metres one needs to consider the thermal inertia of the surrounding soil. Cableizer offers an alternative approach to calculate the ampacity with an equivalent depth for deeply buried objects.

Partial soil drying-out according to VDE 0276-1000 (2021-04-06)
In addition to the existing IEC 60287 method, partial soil drying-out can now also been calculated based on the VDE standard 0276-1000, a method that is especially suitable for cyclic loads. It is also know as 'Heinhold' method due to its publication in the famous book by L. Heinhold and R. Stubbe. The method is based on the brilliant work from Dipl.-Ing. Franz Winkler from Siemens AG.
