Comparative Study of Conductivity in Mid-Voltage Cable XLPE Insulation
Description
It is well established that space charge conditions
insulation lifetime. Because of this, space charge
formation and relaxation processes characterization has
become a very active research field, not only from an basic
science point of view, but also in order to improve
insulation performance in cable and other devices.
In the case of mid-voltage power cable, crosslinked
polyethylene is widely used as insulator. Service temperature
of such cables is around 90°C, which in the case
of the cable insulation studied is in the melting temperature
range. In previous works it has been determined that
at this temperature conductivity plays a relevant role in
the space charge relaxation process, so that the characterization
of conductive processes at service temperature
may become important in order to enhance cable insulation
performance. The aim of this work is to contribute to
a better knowledge of the conductive properties of XLPE
in both time and frequency domains.
