Stress control tube
Stress control tube for cable termination
This is an example of the cable termination simulation, performed with QuickField software.
Axisymmetric problem of transient electric.
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.
Calculate the effect of electric stress reduction.
With stress control tube the maximal electric stress reduces from 1.6 to 0.5 kV/mm.
