Abstract
The use of composite materials, e.g. fibreglass materials,
in overhead transmission line systems is nothing new.
Composite based insulators have been applied to
transmission lines for over 30 years, mainly as
suspension and post insulators and often as an option for
special applications. Also towers and recently
conductors based on composite materials are available
at transmission levels.
In this paper it is investigated which composite based
solutions are available in connection with complete
overhead line systems including insulators, towers and
conductors. The components are reviewed with respect
to solved and persisting known failures/problems of
both mechanical and electrical nature. Major challenges
related to extensive use of composite materials in an
overhead line system are identified, as are possible
benefits - both when using standard as well as
customised composite components, e.g. insulating
crossarms combining the electrical insulating properties
of composites with their excellent mechanical strength.
The paper will also cover specific design proposals, as
investigated in a PhD project on composite based
overhead line systems currently being carried out in
collaboration between the Technical University of
Denmark and the Danish TSO, Energinet.dk.
