摘要
介绍了新型耐热导线技术的发展、特点及其应用情况。与传统的钢芯铝导线相比,新型耐热导线具有载流量大、耐高温、弧垂低等优点,因此广泛应用在城网线路增容、线路大跨越等场合。随着国民经济与陕西电网负荷的增长,新型耐热导线在陕西电网中将得到广泛的应用并产生显著的经济效益。
The development, characteristics and application of new heat resistance wire are introduced. Compared with traditional steel cored aluminum stranded wire, the new heat resistance wire has the advantage of high current carrying capacity, high temperature resistance, low arc sag, therefore it is widely applied in the condition of line capacity incensement and long span power line. With the development of domestic economy and load increasing of Shaanxi power grid, the new heat resistmlce wire shall be widely used in Shaanxi power network and obtains obvious economic benefit.
