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.
Problem Type:
3D extrusion electrostatics.
Geometry:
Given:
Relative permittivity of air ε = 1,
Relative permittivity of insulation ε = 2,
Relative permittivity of filler ε = 2.2,
Relative permittivity of sheath ε = 1,
Potential difference ΔU = 1 kV
Problem:
Find electric field strength distribution.
Results:
Electric field stress distribution
