架空线路的施工规范方法及步骤如下：

The construction methods and steps of overhead lines are as follows:

线路测量：根据设计图勘察地形地物，确定线路起点，转角点和终端店的电杆位置， 后确定中间电杆和加强杆位置并插上标桩。

Line survey: According to the design map, survey topographic features, determine the line starting point, corner point and pole position of terminal store, and finally determine the middle pole and strengthening pole position and insert the stake.

基坑挖掘机回填：挖掘基坑时应注意土质及周围环境，坑口尺寸一般为宽0.8米、长0.3米。拉线坑口尺寸一般为宽0.6米、长1.3米。电杆埋设深度参考值如下表：

Backfilling of excavator for foundation pit: When excavating foundation pit, attention should be paid to soil quality and surrounding environment. The size of pit mouth is generally 0.8 meters wide and 0.3 meters long. Wire pit size is generally 0.6 meters wide and 1.3 meters long. The reference values of pole burial depth are as follows:

水泥杆杆长（米） 7 8 9 10 11 12 15

Cement pole length (m) 7 8 9 11 12 15

埋设深度（米） 1.1 1.6 1.7 1.8 1.9 2.0 2.5

Burial depth (m) 1.1.6 1.7 1.8 2.0 2.5

杆塔基础和拉线基础回填时不准回填树根、杂草等物、土壤应夯实两遍以上，回填后应高出地面30~50厘米。

When backfilling tower foundation and cable foundation, it is not allowed to backfill tree roots, weeds and other materials, soil should be compacted more than twice, and should be 30-50 centimeters higher than the ground after backfilling.

立杆：电杆是架空线路中用来支撑导线的。电杆的类型很多，按其作用常见的有直线杆、转角杆、终端杆等。常用的立杆方法有：起重机立杆、三脚架立杆、倒落式立杆和架脚立杆。JG硅橡胶电机引接线 JG硅橡胶电机引出线

Standpole: Poles are used to support conductors in overhead lines. There are many types of poles. According to their functions, there are linear poles, corner poles, terminal poles and so on. Commonly used vertical pole methods are crane pole, tripod pole, upside-down pole and frame pole.

三角架立杆是一种较为简单的立杆方式，它主要依靠在三角架上的小型卷扬机来吊立电杆，立杆时先将电杆移到坑边，立好三角架，在电杆梢部结三根拉绳，以控制杆身，然后将电杆竖起落在杆坑中， 后调整杆身，填土夯实。

Triangular pole is a relatively simple way of pole erection. It mainly relies on a small winch on the tripod to lift the pole. When the pole is erected, the pole is moved to the edge of the pit, the tripod is erected, and three pulling ropes are tied at the tip of the pole to control the pole body. Then the pole is erected and landed in the pole pit, and the pole body is adjusted and compacted with earth.

横担组装：横担是安装绝缘子、开关设备、避雷器等的支架。按材质分有木横担、铁横担和陶瓷横担等。直线杆横担应装设于负荷侧，非直线杆应装设于张力反侧。

Crossbar assembly: Crossbar is a bracket for installing insulators, switchgear, lightning arresters, etc. According to the material, there are wooden, iron and ceramic crossbars. The crossbar of the straight bar shall be installed on the load side, and the non-straight bar shall be installed on the reverse side of the tension.

绝缘子：绝缘子是用来固定导线的。所以它应有足够的电气绝缘性能和机械强度。架空线路 常用的绝缘子有针式绝缘子、悬式绝缘子、蝶式绝缘子等。低压绝缘子额定电压1kV，高压绝缘子用于 3kV、6kV、10kV线路。

Insulators: Insulators are used to fix wires. So it should have enough electrical insulation performance and mechanical strength. The common insulators used in overhead lines are pin insulators, suspension insulators, butterfly insulators and so on. The rated voltage of low voltage insulators is 1 kV. High voltage insulators are used in 3, 6 and 10 kV lines.
