供应 春晨 JBQ电机引接线 JBQ电机引出线

江苏春晨电缆有限公司生产JBQ电机引接线，

第一节架空线路 架空线路具有造价低，取材方便，施工容易，检修方便的特点。常用来作远距离传送电能用。架空 线所用的主要部件有：导线、避雷器、绝缘子、杆塔及基础、拉线、固定夹具等。结构如下右图所示：架空电力线电杆架设结构图

The first section of overhead line has the characteristics of low cost, convenient material acquisition, easy construction and convenient maintenance. It is often used for long-distance transmission of electric energy. The main components used for overhead wires are: conductors, lightning arresters, insulators, poles and towers and foundations, wires, fixtures, etc. The structure is shown in the right figure as follows: the erection structure of overhead power line poles

架空线路的一般要求

General requirements for overhead lines

架空线路应广泛采用钢芯铝绞线或铝绞线。高压架空线的铝绞线截面不得小于50平方毫米，芯铝绞线截面不小于35平方毫米；空线截面不16平方毫米。JBQ电机引接线

Steel-cored aluminium strands or aluminium strands should be widely used in overhead lines. The section of aluminium strand of high-voltage overhead wire shall not be less than 50 square millimeters, the section of core aluminium strand shall not be less than 35 square millimeters, and the section of empty wire shall not be less than 16 square millimeters.

导线截面应满足最大负荷时的需要。

The section of conductor should meet the need of maximum load.

截面的选择还应满足电压损失不大于额定电压的5％（高压架空线）、或2％~3（对视觉要求较高的照明线路）。并应满足一定的机械强度

The selection of cross section should also meet the voltage loss of no more than 5% of the rated voltage (high voltage overhead line), or 2%~3 (lighting line with higher visual requirements). And it should satisfy certain mechanical strength.
