We can save. (A) It is possible to save a great deal of cost and labor for constructing and removing a temporary tower (main pillar) for temporarily relocating and placing an existing power transmission line. (B) It is not necessary to secure a new site outside the site of the existing transmission tower. (C) Alternatively, there is no need to carry out construction with safety problems, such as mounting an unstable long temporary arm to temporarily transfer the power transmission line to an existing steel tower. (D) In the process of constructing the new transmission tower, the new and old main pillars are connected with a detachable connecting jig, so that unique and difficult work can be performed safely and reliably. (E) Combining various types of new and old transmission towers,
Only one type of connecting jig can be shared for each construction. (F) Throughout the entire period of the construction work, the construction work can be advanced while a part of the plurality of power transmission lines remains in the live state. (G) Therefore, there is no need to seriously hinder the plan for supplying power to consumers.
