Abstract

An object of the invention is to provide a cable capable of matching exposed dimensions of conductors with a predetermined dimension to perform good processing at the time of distal end processing. In a cable (10) in which a pair of insulated wires (1) each of which is formed by covering a conductor (4) with an insulator (5) is mutually stranded and a periphery of these stranded insulated wires (1) is covered with a sheath (6) made of an inner sheath (2) and an outer sheath (3), the conductor (4) is formed by assembling a plurality of stranded wires (4a) each of which is formed by wholly stranding a plurality of wires (4b), and by further wholly stranding the stranded wires (4a).

Claims

1. A cable comprising:

a pair of insulated wires each of which is formed by covering a conductor with an insulator is mutually stranded and a periphery of these stranded insulated wires is covered with a sheath made of an inner sheath and an outer sheath,

wherein the conductor is formed by assembling a plurality of stranded wires each of which is formed by wholly stranding a plurality of wires, and by further wholly stranding the stranded wires,

wherein the insulator is in contact with the conductor, and

wherein a ratio of an adhesion between the conductor and the insulator to an adhesion between the insulated wire and the sheath is 0.59 or more.

2. The cable as claimed in claim 1, wherein an adhesion between the conductor and the insulator is 32 N/35 mm or more.

3. The cable as claimed in claim 2, wherein the insulator comprises polyethylene and the inner sheath comprises polyethylene or thermoplastic polyurethane.
