PTI-ASDA Research Program Into Compact Transmission Lines and HPOF Cables. Part II. Cables.

摘要

Tests and analyses have been conducted on an experimental 345kV underground cable system operated in the forced cooled mode. Evaluation of the thermal and hydraulic characteristics of forced cooled High Pressure Oil-Filled (HPOF) systems indicate that under appropriate conditions,up to twice the normal capacity of self-cooled feeders is attainable. Information is presented to assist cable engineers and utilities to design and operate underground cable systems with greater reliability and cost effectiveness.
