Introduction of the Advantages and Disadvantages of Power Cable Line

Advantages and disadvantages of power cable lines. 

In recent years, with the rapid development of the power industry, the demand for cable installation in urban power grid renovation is increasing, and at the same time, the demand for its installed products is also more. 

In cable installation and maintenance, cable faults are difficult to find and repair, and are not as easy to repair as overhead lines. 

Therefore, it is of great significance to do a good job in the operation and maintenance management of cable lines for the safe and economical power supply of the power grid.

A power cable line is a transmission and distribution line that uses cables to carry electrical energy.

Cable Line

Power cable lines are generally laid underground or underwater, and there are also overhead power cable lines. 

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.

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

3 The cable is concealed underground, which is safer for the person 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.
