A review of electric utility's experiences with polymeric insulators
(December 2004)
Abstract
This paper presents the current literature about
utilities service experience with polymeric
insulators, who have similar environmental
conditions as the one prevailing in the Gulf Council
Countries (GCC). The polymeric insulators
provided very satisfactory performance in many
areas of the world, especially to combat high
pollution conditions, which is a min concem for the
reliability of the HV transmission network in the
Gulf. The GCC service experience with polymeric
insulator is still limited with respect to period of
utilization. Other countries service experience can
provide additional informing experience with
polymeric insulators. Laboratory tests and inservice
inspection are very important for careful
selection of the suitable insulator types. The main
objective of this paper is to present a thorough
literature review and investigations of local and
international electric utility's experiences with
polymeric insulators. The paper will also present
the major procedure needed to assess the
performance of such insulators in the GCC area.
