However, the cross arm is stressed more, and the problem of cross arm deformation often occurs. In addition, the transverse bending moment of the iron tower is increased due to the existence of the cross arm, besides wind load, bending moment generated by the vertical load of the lead is also larger.

The invention aims to solve the technical problems that: the door type suspension cable pulling tower and the method are provided for solving the problems that a cross arm of an existing self-supporting door type tower is easy to deform and the torque is large.
The technical scheme of the invention is as follows: a door-type catenary tower, comprising:
a first tower body;
the second tower body is separated from the first tower body and is adjacently arranged;
characterized by further comprising:
the stay wire comprises a first end, a second end and a middle part, wherein the first end is arranged on the outer side surface of the first tower body and is connected with a stay wire foundation arranged on the ground, the second end is arranged on the outer side surface of the second tower body and is connected with a stay wire foundation arranged on the ground, and the stay wire penetrates through the top of the first tower body and the top of the second tower body;
and the two V-shaped insulator strings are respectively hung between the first tower body and the middle position of the stay wire, and between the second tower body and the middle position of the stay wire, and the V-shaped insulator strings are used for hanging wires.
The top of first body of a tower is provided with first ground wire cross arm.
The top of second body of the tower is provided with second ground wire cross arm.
The beneficial effects of the invention are as follows: the invention replaces the existing cross arm of the self-supporting type door-shaped tower with the pull wire to form the door-shaped suspension cable pull wire tower, which not only can avoid the problem of cross arm deformation of the self-supporting type door-shaped tower, but also has the advantage of small pole spacing of the door-shaped tower, and simultaneously can avoid torque, the stress of the two columns is mainly vertical load, and the weight of the tower is the lightest.
