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
