AI Technical Summary
Technical Problem
At the intersection of transmission lines, the existing technology requires the installation of multi-based towers, resulting in large area, large construction volume, high cost, and long power outages during construction, affecting people's livelihood.
Method used
A double-loop cross-span dry-shaped tower is designed. By setting up upper and lower conductor cross-spans with upper and lower conductor cross-spans arranged at the same transmission tower with different lengths, the cross-spans of double-loop transmission lines with different directions is achieved.
Benefits of technology
The design saves the floor area, reduces construction volume and construction cost, shortens the power outage time during construction, and improves the safety and reliability of the tower.

Abstract
The utility model belongs to the technical field of power transmission line iron towers, and particularly relates to a double-loop crossed spanning power transmission iron tower which comprises tower legs, a tower body and a tower head. The tower head comprises an upper tower head section and a lower tower head section which are adjacently arranged up and down; the upper tower head section is provided with an upper ground wire support and an upper wire cross arm which are vertically spaced and arranged in parallel. The lower tower head section is provided with a lower ground wire support and a lower wire cross arm which are vertically spaced and arranged in parallel. The projections of the upper wire cross arm and the lower wire cross arm on the horizontal plane intersect with each other. By arranging the upper wire cross arm and the lower wire cross arm which are vertically arranged at intervals and are different in length direction, double-loop power transmission lines in different directions are crossed and spanned at the same power transmission tower, the occupied area is saved, the construction amount is reduced, the construction cost is saved, and the power failure time during construction is shortened.
