In power lines, the proportion of cables is gradually increasing. 

Power cables are cable products used to transmit and distribute high-power electrical energy in the backbone of power systems, including various voltage levels of 1-500KV and above, and various insulated power cables.

Power cables are cables used to transmit and distribute electrical energy. 

Power cables are commonly used in urban underground power grids, power station outlet lines, internal power supply for industrial and mining enterprises, and power lines under river water.

The followings are the advantages and disadvantages of cables.

The main advantages are:

1 Due to the influence of external factors (such as lightning, wind damage, bird damage, etc.), its power supply reliability is high.

2 The power cable is buried underground, and the project is concealed, so it has little impact on the city's appearance environment. 

   Even if an accident occurs, it will generally not affect personal safety.

3 The cable capacitance is large, which can improve the line power factor.

The disadvantages are:

1 High cost, large investment in one-time construction, and investment in cable lines are about 10 times that of overhead lines of the same voltage level.

2 It is difficult to branch the line.

3 The fault point is difficult to find, and it is inconvenient to deal with the accident in time.

Power cable lines are generally laid underground or underwater, and there are also power cable lines laid overhead. Power cable lines are mainly composed of cables, cable intermediate connectors, cable terminations, etc. 

Some power cable lines also have accessories, such as pressure boxes, pressure and temperature warning devices. Underground power cable lines also include corresponding civil facilities, such as cable trenches, pipes, shafts, tunnels, etc.

Power cable lines have the following advantages over overhead lines:

1. Cable is laid underground, does not occupy the ground, space, the same underground cable channel, can accommodate multiple return lines;

2. In urban roads and large factories, power supply by cable is conducive to city appearance and factory appearance;

3. Natural meteorological conditions (such as lightning, wind and rain, salt spray, pollution, etc.) and the surrounding environment have little effect on the cable;

4. The cable is concealed underground, which is safer for the human body and has high reliability of power supply; the operation and maintenance cost of the cable line is relatively small.

Compared with overhead lines, power cable lines have the following disadvantages:

1. The investment cost of cable line construction is relatively high, which is several times that of overhead lines;

2. Cable fault concealment, testing is difficult;

3. After the cable is damaged, the repair time is longer;

4. Cable is not easy to branch;

5. Cable and accessory selection, cable sheath grounding method, cable laying method, pollution area distribution, civil construction type and capacity.

The power engineering construction standard clearly states that the cable pipe sealing and waterproofing in cable laying must meet the standard. It is related to whether the maintenance and expansion work in the future will proceed smoothly.
