Abstract (en)
[origin: EP2184744A1] The wire (22) has a central conductor (24) maintained by a spacer (30) in a PTFE based sheath (26). The sheath and the spacer form longitudinal and continuous cells (28). The cells are defined partially by the conductor. The spacer includes a radial junction portion (32) that forms a relatively thin or narrow separator partition between the adjacent cells and a broader maintaining portion (34) that is formed at a point of contact between the spacer and the conductor. Independent claims are also included for the following: (1) a coaxial cable including a PTFE based tubular intermediate sheath separated from a central conductor (2) a method for manufacturing an electric wire (3) a tool for manufacturing an electric wire.
