The 100mm of the lower side of the cross arm 2 can not only ensure a safe distance from the wires above the pole, but also ensure that the pull contact points of the wire pull wire and the windproof pull wire to the pole are moved up as soon as possible, so that the pull force arm is shorter and less affected. Force performance is better.

As shown in Figure 3, one end of the anti-icing and anti-wind backguy wire 4 fixed on the ground is provided with a chassis 41 and a chuck 43, and one end of the anti-icing and anti-wind backguy wire 4 fixed on the ground is clamped and fixed to the chuck 43 to be connected, and the chuck 43 It is connected with the chassis 41 through a stay rope, and the chassis 41 is pre-buried in the ground.
