二、产品性能指标

电(dian)(dian)线(xian)使用技術(shu)指(zhi)标值具备GB/T1179-2008和祖国农电(dian)(dian)集(ji)团(tuan)《锦(jin)屏~苏南±800kV特进行高压电(dian)(dian)流电(dian)(dian)缆(lan)线(xian)JL/G3A-900/40-72/7,JL/G2A-900/75-84/7 技術(shu)经(jing)济水平》、《JL/G3A-1000/45-72/7钢芯铝(lv)绞(jiao)合(he)技術(shu)经(jing)济水平》。

其主要(yao)指标(biao)体系为:

1. 铝(lv)单线(xian)的导(dao)电(dian)率≥61.5%IACS。

2. 铝单(dan)线拉伸承(cheng)(cheng)载(zai)力承(cheng)(cheng)载(zai)力≥160Mpa,拉伸承(cheng)(cheng)载(zai)力承(cheng)(cheng)载(zai)力一致性(xing)≤25Mpa。

3. 20℃时绝缘线直流电压电容(rong)为(wei):JL/G3A-900/40-72/7 ≤0.0319Ω/km

(发展中部委规定(ding)GB/T1179≤0.0321Ω/km);JL/G2A-900/75-84/7 ≤0.0319Ω/km(发展中部委规定(ding)GB/T1179≤0.0321Ω/km);JL/G3A-1000/45-72/7 ≤0.02862Ω/km(发展中部委规定(ding)GB/T1179≤0.0289Ω/km。
