Title:
ELECTRICAL WIRE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2010/123105
Kind Code:
A1
Abstract:
Disclosed are: an electrical wire which is reduced in the diameter, while achieving excellent wear resistance; and a method for producing the electrical wire.
Specifically disclosed is an electrical wire (1) wherein a center conductor (2), an insulating body (4), an outer conductor (6) and an outer cover (7) are sequentially arranged concentrically. The center conductor (2) is obtained by twisting copper alloy wires (3) which contain not less than 1% by weight but not more than 3% by weight of silver and has a wire diameter of not less than 0.010 mm but not more than 0.025 mm, and has a tensile strength of not less than 950 MPa and an electrical conductivity of not less than 70% IACS but not more than 85% IACS. The outer cover (7) is formed from an ETFE having a melt flow rate of not less than 25 but not more than 45, and has a thickness of not less than 10 μm but not more than 30 μm, and an outer diameter of not more than 0.35 mm.
