[0002] With the acceleration of urbanization, many power facilities have been built in various cities in my country, which have brought many conveniences to people's daily lives. Common transmission (distribution) lines include cable lines and overhead lines. Overhead lines are highly praised because they save investment compared to cable lines and are easy to operate and maintain.
[0003] Line pole towers are used to support conductors and lightning conductors. According to the different materials of the pole towers, they are divided into wooden poles, reinforced concrete poles, iron towers, and steel pipe poles. The pole towers can be divided into two types: straight-line and tension-resistant.

The pole head layout completely adopts the typical design scheme. The straight-line pole head is arranged in a triangle, and the tension-resistant pole head is arranged horizontally. The straight-line pole tower is the most commonly used pole tower in the line, generally accounting for more than 80% of the total number of pole towers on the entire line. Under normal circumstances, it only bears the wind pressure and weight of the conductor, the structure is relatively simple, the material consumption is small, and the cost is low. However, with the increasing demand for urban electricity load, the problem of the safe distance between the straight-line pole towers of overhead distribution lines and the houses under construction is particularly prominent.

Straight crossarm diagonal braces and clamps are installed under the straight crossarm to support and strengthen the crossarm. When the pole head conductor is too close to a house or other obstacles (crossing objects), the safety distance requirement of the conductor to the ground cannot be met, and there is a risk of hidden dangers in safe use of electricity.
