[0025] Example: such as figure 2 Medium composite material towers, taking 110kV line towers as an example, are designed according to the linear tower with a line span of 300m, and the main parameters of the tower can take the following values: D 1 =D 2 = 3.0m, D 3 = 3.0m, r A = 1.2m, r B = r C = 1.5m, the creepage distance of the insulating cross-arm is 3650mm. First of all, the clearance distance of each pole tower meets the design requirements of 110kV line (the minimum phase-to-ground clearance distance is greater than 1.0m, the insulation creepage distance is not less than 3650mm in Class III polluted areas, and the horizontal insulation distance between phases is D 1 satisfy ≥ 0.4 L k + U / 110 + 0.65 f c , Vertical insulation distance between phases D 2 satisfy ...
