PURPOSE:To reduce the weight by wind pressure by planting a taper pole thinner toward its top onto ground, suspending a sub-conductor from the top to the ground face with an expanded interval and making equivalently said pole and the sub-conductor equal in the thickness. CONSTITUTION:The taper pole 11 having an equivalent radius rho1 thicker at ground 12 and thinner toward the top 11a is planted solidly vertically to the ground 12. Then the sub-conductor comprising two conductors 13a, 13b is suspended from the top 11a of the pole 11, the tip is tensed from the ground 12 via an insulator 15. Then a transmitter 16 is connected to the subconductor 14 clipping the insulator 15 and power is applied. Further, the equivalent radius rho2 of the sub-conductor 14 is made thicker toward the ground and thinner toward the top 11a, and the interval D between the pole 11 and the sub-conductor 14 is wider toward the ground 12 and narrower toward the top 11a. |
