Abstract
Aluminum clad steel stranded conductor has a bright application prospect in long span transmission line project because of its large tensional force and small sag.However,its application is limited due to its low ampacity.Based on the testing verification,the paper illustrates that the maximum allowable operating temperature of aluminum clad steel stranded conductor,can be increased up to 130 ℃ and its ampacity can be greatly increased as a result.This testing result gives us a new idea on designing long span transmission line projects.
