Patent number: 10056171Abstract: Protrusion portions and recess portions are formed on a metal layer. The protrusion portions are repeatedly formed in a lattice shape at a pitch of P. Similarly, the recess portions are repeatedly formed in the lattice shape at the pitch of P. The protrusion portions and the recess portions are arranged in the same arrangement direction and arranged shifted to each other by half the pitch in the arrangement direction. The protrusion portions and the recess portions are formed independently of each other without contacting each other. In order to allow a multilayer tape to reliably follow the bending deformations of a power cable (submarine cable) in all directions, in an arbitrary cross-section taken in the longitudinal direction of the multilayer tape (in the axial direction of an impermeable layer), the protrusion portions or the recess portions are necessarily arranged at predetermined intervals.Type: GrantFiled: February 5, 2016Date of Patent: August 21, 2018Assignee: FURUKAWA ELECTRIC CO., LTD.Inventors: Hiroki Manabe, Hiroyuki Sakakibara, Masahiro Minamide
