The invention provides a compact type tri-connection V-shaped suspension string for a light-ice area. The compact type tri-connection V-shaped suspension string comprises a suspension connection plate and two suspension string bodies distributed in a V-shaped mode. Each suspension string body comprises a composite insulation sub-string formed by connecting composite insulators, and the two ends of the composite insulation sub-string are connected with an iron tower cross arm and a suspension connection plate respectively. A connection plate I and a Z-shaped right-angled hanging plate II are sequentially arranged between the composite insulation sub-string of one tri-connection suspension string body and the suspension connection plate; a connection plate II and a right-angled hanging plate are sequentially arranged between the composite insulation sub-string of the other tri-connection suspension string body and the suspension connection plate. Compared with the prior art, the compact type tri-connection V-shaped suspension string for the light-ice area has the advantages that the structural strength of hardware fittings and the overall intensity of the suspension string are improved, and normal operation of an electric transmission line is guaranteed; meanwhile, the length of the suspension string is effectively shortened, accordingly, the height of the tower body of the electric transmission iron tower is reduced, and the manufacturing cost, the transportation cost and the construction cost of the hardwire fittings and the iron tower are lowered.
