摘　　要：根据目前城区输电线路设计情况,按塔头挂线布置型式提出了线路走廊宽度的对比及窄基钢管塔的适用性,按城市的不同地段且考虑是否跨房拆房等情况,分析了四回路角钢塔、四回路钢管杆及六层布置的窄基钢管塔的经济性。According to the current design of urban transmission line, the contrast of layout type of transmission line was proposed for transmission line corridor width and the applicability of narrow base steel tube tower was analyzed. The economy of four-circuit angle steel tower, four-circuit steel tube tower and six-layer narrow steel tube tower was compared by consideration of diferent sections of the city and the situation of room demolition.
