Therefore, when placed over the center conductor, it lacked stability and was prone to tilting or coming off the center conductor.
またこれらは開口部があるためそれを高圧電線
に使用したのでは電気的絶縁性が悪く、高電圧が
加わると開口部から絶縁破壊が生じるという問題

It is drawn out in a separate process and coated on the outer periphery of the insulating support 1 with a metal band-shaped sheath material 12 made of aluminum, copper, stainless steel, etc.
The sheath material 12 is placed vertically on the forming roller 13.
The sheath material 12 is gradually bent into a tubular shape to continuously cover the outer periphery of the insulating support 1, and then the joints of the sheath material 12 are welded using a welding machine 14. This welded part is inspected with a welding inspection device, and straightened with a straightening device 1,
Thereafter, corrugation is performed using a corrugator to form a corrugated sheath 9.
