TENSION INSULATOR DEVICE FOR LARGE BUNDLE DIAMETER SIX-CONDUCTOR POWER TRANSMISSION WIRE

摘要

PURPOSE:To make electric wire side holding back yokes small and light, by holding back large bundle diameter 6-conductors under a condition in which the connection metal fitting set connection point interval of both right and left horizontal yokes and both the upper and lower connection metal fitting set connection point intervals of vertical yokes are made narrower than the opposing conductor intervals of respective large bundle diameter 6-conductors. CONSTITUTION:Tension clamps are connected to one end of a horizontal yoke 18 and both the upper and lower ends of a vertical yoke 28 respectively through connection metal fitting sets. Moreover, both connection metal fitting sets are connected by means of expansion metal fittings 25, 38 so that the interval of both tension clamps connected to right and left horizontal yoke 18, 18 and the interval of both tension clamps connected to a vertical yoke 28 become equal to the opposing conductor intervals of large bundle diameter 6-conductors. The interval of both vertical yokes 28, 28 is held to be the large bundle diameter 6-conductor opposing conductor interval. Accordingly, large bundle diameter 6-conductors can be held back by means of electric wire side holding back yokes made up of yokes 18, 18 and yokes 28, 28. As a result, electric wire side holding back yokes small and light are realized.
