This is an example of the cable termination simulation, performed with QuickField software.
Axisymmetric problem of transient electric.
Central conductor potential V = +4 kV.
Screen potential - 0 V (grounded).
Relative permittivity ε of :
air - 1.
insulation - 2.
shield - 1.2.
stress control tube - nonlinear:
Calculate the effect of electric stress reduction.
With stress control tube the maximal electric stress along the cable surface reduces from 1.6 to 0.6 kV/mm.
