Comparison of Power Cable Lines with Overhead Cable Lines

Power cable line compared with overhead power line, has many characteristics and advantages.

Its main advantages as follows:

1.Reliable power supply, cable connections are not affected by external interference, such as lightning, wind damage, ice, kite and bird damage, etc. Nor does it exist common broken downline overhead lines, porcelain flashover broken, and due to wire caused by the short circuit and ground fault.

2.No need to set up poles and wires on the pavement, saving wood, steel and cement. In urban areas, in particular, it can reduce the harm to human beings and make the city appearance neat and beautiful.

3.The influence of pavement structure is lesser, suitable for laying in city area.

4.Simple and convenient operation, small maintenance workload, the cost is lower.

5.Underground laying, more hidden, is conducive to national defense secrecy.

6.The large capacitance of the cable helps to improve the power factor of the power system.

Although the cable has many advantages, but also has the following deficiencies.

1.High cost, one-time investment costs more.

2.Difficult to change after laying, not suitable for temporary use.

3.The branch joint of the cable line is difficult to solve.

4.Difficulty in finding fault, it's not as obvious as overhead lines.

5.The repair and recovery time is long, the production process of the cable joint is high, must have the specially trained mechanic to operate the waterproof joint.

In summary, whether the use of cables, should be based on the actual situation with overhead lines after a comprehensive comparison decision.
