Considerations for cable laying

Posted on February 27, 2018

The service reliability of a cable systems depends not only on the quality of the cable itself, but also to a large extent on the methods used and the care taken in laying the cable. In this blog post we list some things you should consider.


Two phase concentric cables

Posted on January 21, 2018

A concentric cable has a conductor around the core for a return path. DC cables may be of concentric type as is the case in an integrated return conductor cable, where the return conductor is installed around the core conductor. Such cables are not directly covered by IEC 60287 but Cableizer implemented a method from CIGRE.


Cables crossing external heat sources

Posted on January 20, 2018

With the web-based cable calculation software Cableizer.com you can calculate the current rating of cables crossing external heat sources. It allows to calculate the current rating or temperatures of multiple cable systems crossing at any angle multiple other cable systems or heat sources. To our knowledge, Cableizer is the only commercially available software that allows to calculate the crossing of multiple systems with multiple other systems.


Cableizer validation test suite 2016 Q4

Posted on January 15, 2017

Continuously validating Cableizer is a task we take serious. Our extensive test suite is a supportive tool to verify our calculations after modifications in the formulas or solver routine.


A new approach for the next generation of Superchargers

Posted on January 14, 2017

DC Fast Chargers are designed to charge electric vehicles quickly with an electric output ranging between 50 kW – 120 kW, like the Supercharger from Tesla. At a typical 400 volts, this results in a current of 300 amps. A new target is 350 kW resulting in a current of almost 900 amps. For this, a new approach is needed for the DC supply cables.


Two armour layers with separation

Posted on September 2, 2016

Calculating the ampacity of a cable system correctly starts with the precise modeling of the cable. The user shall be able to model a cable as close to reality as possible, visually, electrically and thermally. As a result from our participation at the Cigré 2016 in Paris, we have now introduced a separation layer between the two metallic armour layers.


Cyclic loading with daily, weekly, and yearly load factors

Posted on August 16, 2016

Using the Neher McGrath method for the calculation of the rating of buried cables under cyclic loading conditions allows for a daily, weekly, and yearly load factor in the same calculation.
