What are the ways of laying cables?

Qinzghou cable manufacturer specializes in producing all kinds of wires and cables. The laying methods of cables are as follows: direct burial laying, pipe laying, shallow groove laying, cable trench laying, cable tunnel laying, and overhead laying.

Several methods of cable laying have advantages and disadvantages. Generally, urban development planning, the density of existing buildings, the length of cable lines, the number of cables, and the impact of the surrounding environment should be considered. Technically, the cable tunnel method and the cable trench laying method are convenient for the construction, maintenance and repair of the cable. In some developed cities, public tunnels have been considered in urban planning and construction. Practice has proved that the operation effect of public tunnels is good, which greatly reduces the number of repeated investments and the phenomenon of repeated road excavation. However, the initial investment is huge and the building materials cost money. In China, due to various factors, this laying method is very rare. opgw cable

In contrast, direct burial laying and shallow groove laying are economical laying methods. Direct burial cables are the most economical and widely used electricity laying methods. But it is not conducive to the maintenance and repair of the cable. Once a cable fault is encountered, even if the fault point is detected by the tester, the cable trench must be dug again, which is extremely inconvenient. Therefore, the choice of cable laying method should be combined with the actual situation, according to factors such as engineering conditions, environmental characteristics, cable type and quantity, with a development perspective, according to the requirements of meeting the requirements of operational reliability, easy maintenance and technical and economic rationality.
