The utility model provides a two return circuits of X type tangent tower for well ice formation 330kV alternating current transmission line, includes the body of the tower, the symmetry sets up the upper conductor cross arm at the body of the tower top, from last to wire cross arm during the symmetry is provided with in proper order down and wire cross arm down on the body of the tower of upper conductor cross arm below, in and the wire cross arm and down the wire cross arm be connected with the body of the tower respectively, the upper conductor cross arm top on body of the tower top is provided with the ground wire support that is used for hanging the ground wire, and the ground wire support includes two customs stations in the body of the tower top symmetry setting of two branches, this ground wire support. In order to save the tower weight, reduce the cost, a wire string point that sets up bottom well wire cross arm adopts V type insulator chain, and the wire string point of upper conductor cross arm and lower wire cross arm adopts I type insulator chain for see from hanging wire point that the iron tower pattern becomes " hyperbola " type by " drum type " arranges, has shortened wire cross arm length, has reduced the alternate distance and wire cross arm interlamellar spacing of wire.
