耐热导线在深圳输电线路扩容上的应用研究

Study on Applying the Resisted-heat Conductor to Shenzhen Power Transmission Lines for Expanding the Capacity.

本文对耐热铝合金导线在输电线路扩容应用进行了技术研究。围绕老线路扩容改造,在基本不改变原有线路 杆塔的基础上,采用耐热导线可以提高载流量50％。本文结合导线性能和深圳电网扩容工程实际应用等方面进行了阐述。

A technology study on applying resisted-heat Al-alloy conductor to power transmission lines for expanding its capacity has been done in this article. The features of the conductor and the practical application cases in Shenzhen power network have been also expatiated. On the basic of that inhere line steel towers have not be changed approximately, and if resisted-heat conductor has been used, the current carry capacity could be raised to 50% .
