双回路VIV串鼓形直线塔
摘要：
双回路VIV串鼓形直线塔，它主要包括塔身（11），导线横担（12），地线支架（13）和塔腿（14），所述的导线横担（12）包括上层横担（121）、中层横担（122）和下层横担（123），上层横担（121）和下层横担（123）采用V型绝缘子串，中层横担（122）采用I型绝缘子串。目前三相“I ”串的上中导线层间距较大，空间利用率不高；且走廊宽度较大，占有空间大，成本高。三相“V” 在三层横担的杆塔型式中，塔头最高，横担最长，横担正面斜材均为受力材，钢材指标不经济；且绝缘子耗费多。本实用新型VIV串布置型式在节约钢材指标、减小塔头尺寸、优化走廊宽度、保障线路安全运行等方面具有更大优势。
摘要（英）：

A two-circuit vortex inducted vibration (VIV) string drum type straight-line tower mainly comprises a tower body (11), wire cross arms (12), a ground wire support (13) and tower legs (14). The wire cross arms (12) comprises an upper layer cross arm (121), a middle layer cross arm (122) and a lower layer cross arm (123), wherein the upper layer cross arm (121) and the lower layer cross arm (123) adopt V-shaped insulation strings, and the middle layer cross arm (122) adopts I-shaped insulation strings. The distance between the upper wire layer and the middle wire layer of a three-phase I-shaped string is large, and space utilization rater is not high. A corridor is large in width and occupation space, and high in cost. In a three-phase V-shaped cross arm pole tower, the tower head is the highest, and the cross arm is the longest. The diagonal materials of the right faces of the cross arms are force-bearing materials, and the index of steel materials is not economic, and the insulation strings are consumed a lot. The arrangement style of the novel VIV string has the big advantages of saving the steel index, reducing the size of the tower head, optimizing the width of the corridor, guaranteeing safe operation of circuits.
