　　Selection of typical hanging points for optical cables

　　According to the calculation results of the electric field strength of various towers, the hanging points that meet the requirements of electric field strength can be divided into three types: high, medium, and low hanging points. High hanging points are generally difficult to construct and inconvenient for operation and management; However, low hanging points have some issues in terms of ground safety distance and are prone to theft incidents. The middle hanging point method is generally used in information network engineering.

　　110KV line tension poles, portal poles, double circuit iron towers, steel pipe single poles, cement single poles, etc. The optical cable can be hung at a position between 300-500mm below the layer cross arm.

　　5. Distribution of ADSS optical cables

　　The distribution of optical cables is an important issue in the ordering and construction of optical cables. After the adopted lines and conditions are clear, the configuration of optical cables should be considered

　　The factors that affect disk allocation include:

　　(1) Due to the fact that ADSS optical cables cannot be arbitrarily spliced like ordinary optical cables (because the fiber core of the optical fiber cannot withstand force), they must be spliced on the tension tower of the line. Additionally, due to poor conditions at the field splicing point, the length of each fiber optic cable reel should be controlled within 3-5km as much as possible. If the reel length is too long, it is inconvenient for construction; If it is too short, there will be more connections, resulting in significant attenuation of the path and affecting the transmission quality of the optical cable.

　　(2) In addition to the length of the transmission line being the main basis for the length of the optical cable reel, the natural conditions between the towers should also be considered, such as whether the traction machine can travel conveniently and whether the tension machine can be placed.

　　(3) Due to errors in line design, the following empirical formula can be used for the distribution of optical cables:

　　Fiber optic cable reel length=transmission line length x coefficient+construction consideration length+length for fusion splicing+line error;

　　Usually, the "coefficient" includes the sag of the line, the length of the overhead line on the tower, etc. The length considered for construction is the length used for traction during construction.

　　(4) The distance between the ADSS fiber optic cable hanging point and the ground is generally not less than 7m. When determining the distribution, the span difference should be simplified to reduce the types of fiber optic cables, which can reduce the number of spare parts (such as various hanging fittings configured) and facilitate construction.
