Double-loop pole tower with variable nominal height
The invention discloses a double-loop pole tower with variable nominal height. The double-loop pole tower comprises a tower body and a top-layer ground wire cross beam, wherein the top-layer ground wire cross beam has one layer and is provided with a two-sided cross beam perpendicular to a newly-built line direction from the tower body; an upper-layer guide wire cross beam is divided into three layers, wherein each layer is provided with a two-sided cross beam perpendicular to the newly-built line direction from the tower body; a middle-layer auxiliary cross beam has multiple layers and is provided with a one-layer two-sided cross beam perpendicular to the newly-built line detection from the tower body; and a lower-layer ground wire cross beam has three layers in total and each layer is provided with a one-layer two-sided cross beam perpendicular to the newly-built line detection from the tower body. The double-loop pole tower with variable nominal height realizes double-loop drilling with variable nominal height, reduces the possibility of modifying a cross line, burying cables and transforming between a single loop and double loops in a first-spanning and then-drilling project, avoids power failure of the crossed line, increases reliability of a power grid, reduces the construction cost and further reduces height of the transmission line of the newly-built line guide wires of a drilling grade.
