鼎美-芸伟110kVⅠⅡ回线路工程 立塔架线施工方案
新垵变T接110kV鼎美~正东ⅠⅡ回线路工程
（立塔架线施工方案）
一、工程概况：
（一）线路有关情况说明
本工程线路起自110kV芸伟变构架，止于已建110kV鼎康Ⅰ回#9塔、110kV鼎康Ⅱ回#9塔。架空线路全长1.919km，其中双回架空线路长1.84km，单回路架空线路长97m。
新建线路110kV芸伟变构架至新建#14塔采用同塔双回架设，鼎芸Ⅱ回从#14塔引下，改为电缆敷设至已建的鼎康Ⅱ回#9塔，鼎芸Ⅰ回从新建#14塔架空接至已建的鼎康Ⅰ回#9塔。本工程新建铁塔共14基，其中直线塔2基，耐张塔12基，均为钢管杆。
本工程全线导线采用JLHA3-335中强度全铝合金导线，全线安全系数不低于7.0。本工程芸伟变构架~新建#14塔段地线为双OPGW复合光纤地线，两根地线均直接接地；新建#14塔~已建鼎康Ⅰ回#9塔段地线一根为OPGW复合光纤地线另一根为JLB40-80良导体地线，两根地线均直接接地。本工程以芸伟变往已建鼎康Ⅰ回#9塔为线路前进方向，OPGW挂在塔头右侧地线架上，良导体挂在塔头左侧地线架上。
本工程OPGW光缆接至鼎美变构架，因此需将鼎康Ⅰ回、鼎康Ⅱ回原良导体地线更换为OPGW光缆。
