PURPOSE:To prevent the sag of a lead wire in an oil duct by a method wherein a contracting section is built in an oil duct and barrier insulator is inserted. CONSTITUTION:A barrier insulator 3 is held by a contracting section 2a inside a horizontal oil duct 2 placed closely to a rising part 10 of a lead wire 1 to support the lead wire 1. With this structure, a distortion of the lead wire due to its own weight is prevented, so that an insulating distance can be maintained as desired. |
