HIGH TEMPERATURE TESTS OF ACSR CONDUCTOR HARDWARE
(1988)Abstract
Maximum utilization of existing
transmission lines is necessary due to the
difficulties and costs associated with rights-ofway
acquisition and line construction. The
current carrying capacity of an overhead line is a
function of electrical, mechanical, and thermal
phenomena acting upon the conductor and its
supporting hardware. The maximum operating
current of a line is limited by the allowable
hardware temperature,conductor loss of strength,
and conductor sag. This paper reports hardware
temperature data obtained by laboratory tests of
four common ACSR conductors. A summary of the
temperature data and linear equations and graphs
relating conductor and hardware temperatures are
included. As part of the laboratory tests, some
conductor loss of strength data were collected and
are also reported. This study indicates that the
line hardware can operate safely up to conductor
temperatures of 200oC.
