Stress control tube for cable termination
This is an example of the cable termination simulation, performed with QuickField software.
Problem Type:
Axysimmetric problem of transient electric.
Geometry:

Given:
Relative permittivity of air ε = 1.
Relative permittivity of insulation ε = 2.
Relative permittivity of shield ε = 1.2.
Relative permittivity of stress control tube - nonlinear.
Voltage U = 4 kV.
Problem:
Calculate the effect of electric stress reduction.
Results:
With stress control tube the maximal electric stress reduces from 1.6 to 0.5 kV/mm.
