The difference between an aerial cable and an insulated cable1. Aerial cable: non-insulated, bare metal conductor, in air, the insulator string is fixed in the tower, the air is insulated. Main advantages: low cost. The disadvantage is that the use of land resources (line corridor) is more, affects the appearance of the city.2. Power cable: the use of insu...
Cable and overhead line and the advantages of overhead cableAerial cable and power cable, what are the advantages and disadvantages?Answer: distribution line is an important part of the power system, according to the structure can be divided into two categories: overhead lines and cable lines. Overhead lines will be set up in the tower on the wire and expo...
