Features and Uses of ACSR Overhead Conductors

With the development of manufacturing technology in the cable industry, ACCC conductors using carbon fiber instead of steel cores were invented. Compared to ACSR cables, ACCC overhead cables are lighter in weight. This is because it uses a lightweight, small size carbon fiber composite as the core. Carbon fiber not only increases the overall load-bearing capacity of the cable, but also reduces the size of the core.

Compared to ACSR conductors of the same diameter, ACCC conductors provide double the current-carrying capacity. Because ACCC overhead cables can withstand temperatures up to 200 ° C, they can effectively solve the problem of cable sag caused by high temperatures. Bilang karagdagan, thanks to its non-bimetallic construction, ACCC overhead cables are also corrosion resistant.

Existing overhead cables are less often upgraded by removing old lines and then erecting new towers. This method is not only costly, but also has a long construction period. This increases the project cost and extends the construction period to a certain extent. Long outages during the erection of new lines can also affect the number of available devices and the reliability of the power supply to the grid.

The choice of new overhead cables as direct replacements for the original cables both utilizes the original line equipment and minimizes retrofitting. Many of the current upgrades for ACSR overhead lines are direct replacements for ACCC conductors. Gayunpaman, the cost of ACCC cables is high, and if the requirements for cable capacity are not too high, it is still more economical to choose ACSR conductors.
