Abstract

The invention discloses a method for preparing an insulated wire. The wire includes a copper alloy core material, a nickel alloy layer coated on the outside of the core material, the outermost layer is an insulating layer, and the mass of each component of the copper alloy core material is 100%. The content is: Mg 0.6-0.9%, Zn 0.7-0.9%, Mn 0.3-0.4%, Sn 0.6-0.8%, Bi 0.6-0.7%, Al 0.5-0.6%, Ni 0.04-0.05%, Fe 0.06-0.07 %, Co 0.04-0.05%, La 0.05-0.06% and Y 0.02-0.03%, the balance is copper and unavoidable non-metallic inclusions, the preparation method of the insulated wire is by coating the copper alloy wire with nickel alloy and insulating The material thus improves the weather resistance of the copper alloy wire and effectively prolongs its service life.

Description

technical field [0001] The invention relates to a method for preparing insulated wires, and belongs to the field of electric power material manufacturing. Background technique [0002] The basic component of the power industry - power conductors are resources used to transport and distribute electrical energy. Its basic structure consists of wire cores, insulating layers, etc. Among them, the wire core is the conductive part of the power wire, which is used to transmit electric energy, and it is the main part of the power wire; the insulation layer isolates the wire core from the ground and the wire cores of different phases from each other electrically, because copper has good conductivity Copper is widely used in the core of power cables. The conductivity and strength of copper wires in the prior art are difficult to reach high standards at the same time, and the weather resistance is poor. Contents of the invention [0003] The purpose of the present invention is to p...
