The Study on Tension and Thermal Properties of Baised Installed Sleeve

According to previous report, aged sleeves for old transmission lines have variable defects such as biased installed case or corrosion of steel sleeve. Biased installed sleeve occupied 20 percent among the investigated aged sleeves. This defect must cause local heating of splice connector and limit power transmission capacity. It even inspire falling out of overhead conductor from sleeves. This paper studies thermal properties and tension for ACSR conductor in case of biased installed sleeve model. The detailed results were presented in the text.
