摘　　要：I. Introduction A 31.2 km 110 kV transmission line is designed to operateunder 35 kV with conductor model AC-185 (aluminium strand-- 28 x 2.87 mm^2, steel core -- 7 x 2.50 mm^2) at average oper-ating stress of 24. 2%, and overhead ground wire model C-50(steel strand -- 7 x 2.97 mm^2) at average operating stress of20.6%. The whole line has 130 pole-towers, most of which are ofprestressed concrete double-pole structure, as shown in Fig.1.
