PURPOSE: An insulation stand for an overhead line is provided to prevent the disconnection of the overhead line due to temperature change by installing an installation bar and a spring in a mount. CONSTITUTION: An insulation stand includes a mount(10), a pair of installation bars(20,20'), and a pair of springs(30,30'). The mount is fixed in an upper side of a pole. The mount has a guide rail and a stopper. The pair of installation bars are movably mounted in the guide rail. Each installation bar includes an insulator and a guide groove. The insulator fixes the overhead line by a binding unit. The guide groove is formed in the lower side of the installation bar. Both ends of the pair of springs are fixed between the pair of installation bars. The pair of springs elastically support the pair of the installation bars. |
