目的で高張力で延線する。この工法は、所謂高張
力延線工法と言われている。(Conventional technology) The conventional overhead power transmission line construction method is to attach a metal wheel to a steel tower and extend the wire by passing the wire through the metal wheel. In order to prevent this, the wires are stretched under high tension as the wires sag significantly. This construction method is called the so-called high-tension wire extension construction method.

いる。 However, due to recent developments in large-capacity power transmission,
As the diameter of power transmission lines has become thicker, the weight of the wires has increased, and as a result, the tension that acts on the wires during wire extension has increased, so the machines and tools used in overhead line construction methods have also become larger and more powerful. At the same time, problems have arisen in the safety and workability of wire extension work.

連結するものである。 For this reason, low-tension wire drawing methods have recently been studied. The conventional method for this low-tension wire extension method is to suspend multiple hanging wheels at intervals from a hanging wire stretched between steel towers, pass the wire through these hanging wheels, and then transport the wire. The connecting fitting on the wire clamp side and the connecting fitting device on the insulator side are pulled together and connected by a wire tensioning operation using a come-along tool.
