<p>PURPOSE:To make possible installation by the conventional method while preventing damage during the installation by removing a hold winding after it is applied to the circumference of the void type ACSR to check the loosing of the aluminium strand. CONSTITUTION:A hole winding 20 is applied to the circumference of the gas type ACSR 10 with a small void provided between a steel core 2 and the aluminium strand 1 to prevent the loosing of the aluminium strand 1. After an extention, the hold winding is removed. For example, a high tension wire 30 such as a piano wire vertically attached to the void type ACSR 10 over which a hold winding 20 is formed by a gap winding of rubber tape or the like. After this is completed by a conventional method employing a metal wheel, the hole winding is cut away the high tension wire 30 being pulled from the ground. With such an arrangement, the loosening of the strand can be done without any special tool and method thereby enabling a highly efficient installation while the generation of corona can be checked by preventing causative damage.</p> |
