The project addresses a new generation of polymeric high voltage cables with
higher thermal rating performance than conventional polymeric cables for
medium and high voltage applications. It addresses development of the
materials and model cables and life cycle economic-environmental tools which
account for the full life cycle performance including cable deployment and
This project seeks to develop a new generation of polymeric power cable
materials which are required to address the growing Medium Voltage (MV) and
High Voltage (HV) power utility markets in GB and the rest of the world. This
is driven by replacement of existing aged HVAC systems, new power system
connections, especially for renewable (HVDC) and for infrastructure
development. Current polymeric cable materials based on cross linked
polyethylene do not provide adequate high temperature performance; neither do
they offer low environmental impact over their service lives and at end of life.
This proposal seeks to remove these limitations by developing and assessing
new high-temperature low-loss, recyclable polymeric materials, evaluating their
performance in cable designs and by developing and applying a whole-life
assessment tool to quantify the whole life benefits.
