Galloping prevention manner null of bundle conductor

摘要

PURPOSE: To prevent the galloping by attaching a snow adhesion restrainer to the conductor on the side of being caught by the loose catch of a loose spacer. ;CONSTITUTION: Generally, since spacers are attached at intervals of 30-50m, if loose spacers 2 are attached all at once in the longitudinal direction of a transmission line, the conductor 1A on the side of a fixing and catching part 3 does not need the attachment of a snow adhesion restrainer, but the conductor 1B on the side of a loose catch part 4 gets in the same condition as the condition that a single conductor is stretched across, so there is possibility of excessive snowing and icing occurring. Therefore, excessive snowing and icing is prevented by attaching a snow adhesion restrainer (for example, a snow ring) 5 to the conductor 1B on the side of being caught by the loose catch 4. If the snowing and icing is small without becoming excessive, it does not cause large damage even if it is subjected to wind. Hereby, galloping can be prevented.;COPYRIGHT: (C)1993,JPO&Japio
