Abstract: The present invention relates to a yoke for a suspension insulator for an assembly of three electric wires. The yoke includes/: a length unit; and a pair of projections protruding from each side of the length unit. An insulator assembly connection hole for connecting an insulator assembly is formed at one end of the length unit, and a suspension clamp connection hole is formed at the other end of the length unit. Each of the projection units has a suspension clamp connection hole. By supporting three electric wires using a single yoke, the yoke for a suspension insulator for an assembly of three electric wires given in the present invention supports the three electric wires appropriate for DC transmission, accordingly increases utilization of a DC line, and facilitates attachment and installation of an arcing horn. In addition, by integrating the yoke for a suspension insulator, it is expected that the manufacturing process becomes convenient, manufacturing costs and resources are reduced, and maintenance costs are minimized as mechanical defects are prevented because the composition of components is not complex. Furthermore, by arranging the three electric wires in an inverted triangle shape, maintenance work becomes convenient and supporting force for the three electric wires can be increased. Also, as working holes for maintenance or wiring of the suspension insulator are additionally designed, convenience of maintenance work can be improved.
