This article today focuses on XLPE cable advantages and disadvantages.
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.
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.
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.
4 The construction process of cable joints is complicated.
