The laying of the cable laying, the laying of the cable tunnel, the laying of the cable, the laying of the cable, the laying of the cable, the overhead laying, the overhead laying and the underwater laying, etc. Species. Which uses more concentrated way of laying.

1. Power cable laying directly

Direct burial construction is simple, low cost. The safety conditions of the buried cable are good, but the cable is difficult to check when the fault occurs. Replace the cable to dig a large amount of earthwork, and the cable may be corroded by the acid-base material or the ground current in the ground, and the external mechanical damage is not easy to prevent.

Select the direct installation should pay attention to the following matters:

(1) in the chemical corrosion or stray current corrosion of the soil range, shall not be used directly buried.

(2) in the factory area underground pipe network more lots, to be developed there will be frequent excavation of the lot, or high temperature liquid, molten metal spill the lot, should not be used buried.

(3) in the urban sidewalks easier to renovate or road edge, etc., can be used directly buried.

(4) inside and outside the factory is not easy to have frequent excavation lots, should be used directly buried.

(5) the same channel, 35 and below the power cable less than 6 should be used directly buried.

2. Cable laying of power cable

Cable trench laying construction of the earthwork is small, low cost, flexible layout. Cable can be set in one or both sides of the bracket, the cable is arranged on the bracket, the ditch above the set plate. The height of the cable trench is determined by how many cables are laid. Cable trench laying the shortcomings are: construction inspection and replacement of the cable, the need to move a large number of bulky ditch cover.

Selection of cable trench laying should pay attention to the following:

(1) in the factory, the building more underground cable number, and do not use the tunnel, it is appropriate to use cable trench laying.

(2) urban sidewalk excavation inconvenience, and the cable to be laid in phases, it is appropriate to use cable trench laying.

(3) often have industrial water overflow, combustible dust filled the plant, should not use cable trench laying.

(4) in the frequent passage of heavy vehicles through the lot, as well as chemical corrosion of liquid or high temperature melting metal overflow sites, shall not use cable trench laying.
