The utility model discloses an overhead transmission line shaft tower combination formula ground net, include: first ground net, first ground net are mainly made by steel or galvanized steel material material, the second ground net, the second ground net is mainly made by graphite composite material, and a plurality of distance pieces that set up in the certain distance of the every between first ground net and second ground net, wherein: the certain distance in interval and independent each other between first ground net and the second ground net. The utility model discloses an overhead transmission line shaft tower combination formula ground net can prevent the ground net probability that the breakpoint damaged the problem that the ground resistance that causes increases sharply, the sub - accidents of breakdown and flashover of reduced insulation to appear, further reduce the shielding effect between adjacent conductor, reduce the impulse grounding impedance of ground net, the structure is retrencied, the construction of being convenient for, maintenance and maintenance.
