Cable termination

QuickField simulation example

Cable termination is a most loaded part of the cable system, and special measures should be taken to limit the field strength and assure safe and reliable operation. Two conductor high voltage cable terminations may be simulated with QuickField using 3D Extrusion approach.

Engineering question
How to find electric field stress in cable terminations?

Engineering answer
Set up a 3D QuickField Electrostatics problem for a cable termination structure and evaluate electric field stress from computed field results.

Typical applications
power cable insulation systems, cable dielectric layers, conductor insulation assemblies
