　　Types of low voltage distribution lines

　　低压配电线路有两种安装方法，即电缆敷设法和架空线敷设法。

　　There are two installation methods for low-voltage distribution line, namely cable laying method and overhead line laying method.

　　电缆线路因在地下敷设，所以对外界的大风、结冰等自然影响很小，而且地面上不露电线，从而美化了市容与建筑物的环境，但是电缆线路的投资费用较高，检修较困难，架空线路的优点刚好与它相反。所以对于一般无特殊要求的场所，低压配线都采用架空线路敷设法。

　　Because the cable line is laid underground, it has little natural impact on the outside wind and ice, and there is no wire exposed on the ground, thus beautifying the city appearance and building environment. However, the investment cost of the cable line is higher, and the maintenance is more difficult. The advantages of the overhead line are just opposite to it. Therefore, for general places without special requirements, low-voltage wiring adopts overhead lines.

　　低压架空线路一般是用木杆或水泥杆制成电线杆，用瓷瓶把导线固定在电杆的横担上。两根电线杆间的距离在院内约为30~40M，而在空旷的地带可达40~50M，导线之间的距离为40~60厘米，线路的架设尽可能短捷，同时要考虑架设与维护检修的方便。YCB扁电缆

　　Low voltage overhead lines are usually made of wooden poles or cement poles, and the conductors are fixed on the cross arms of the poles with porcelain bottles. The distance between the two poles is about 30 ~ 40m in the hospital, and 40 ~ 50m in the open area. The distance between the wires is 40 ~ 60cm. The erection of the lines should be as short as possible, and the convenience of erection and maintenance should be considered.
