<p>PURPOSE:To miniaturize and lighten a device, by providing yoke pieces respectively on the respective insulator strings of a 3-string insulator string, and arranging the pieces so that lines connecting both the end part positions of the york pieces can become a regular hexagon to connect a conductor to both the end parts of respective york pieces. CONSTITUTION:First and second york pieces 1a and 1b are connected in mutually parallel at the respective middle parts to two insulator strings A1 and A2 on the outside of 3-string insulator strings Al, A2, and A3 arranged in parallel. The middle part of a third yoke piece 1c is connected to the middle insulator string A3 so as to cross orthogonally to the first and second yoke pieces 1a and 1b. Moreover, first and second conductors, third and fourth conductors, and fifth and sixth conductors are connected to both the end parts of the first york piece 1a, to both the end parts of the second york piece 1b, and to both end parts of the third york piece 1c respectively. In an obtained large bundle diameter 6-conductor 3-string strain device, since respective conductors can be allotted sharedly by every two of them by respective insulator strings A1-A3 and an one-peint supporting mechanism is eliminated, eliminating a mechanism withstanding one-point supporting.</p> |
