Abstract
As a city area progresses, it becomes difficult to obtain new routes for overhead transmission lines. In order to utilize existing transmission line equipped with Aluminum conductor steel reinforced (ACSR) and increase capacity at a low cost, low-sag conductors increased in capacity such as Gap Type heat resistance Aluminum alloy conductor steel reinforced(GTACSR) are used. But the cost is rather high, and considerable time and effort is required for sagging operations of conductors.
Therefore we developed the new type low sag conductors increased in capacity which were superior to GTACSR on the performance (capacity, reduction effect of sag). These conductors are easier to install and are at a low cost. Also we investigated the workability and accessories application, the prospects of commercialization are good.
