Experimental Research on Ice Accretion Characteristic of Energy-Saving Conductor

Abstract

New type of energy-saving conductor which can obviously reduce the transmission losses was recently developed in power project. However, considering ice-coating and galloping in winter, it is necessary to investigate its ice accretion characteristic compared with conventional conductor. Research was conducted by icing wind tunnel test. Ice mass and ice shape of conductor with different diameter were examined. There is no clear advantage on the ice-coating resistance capability of energy-saving conductor with small diameter, while for conductor with larger diameter, energy-saving conductor’s ice-coating resistance capability is better than conventional conductor. The test result is helpful for choosing suitable type of large diameter conductor in high and ultra-high voltage transmission project.
