A kind of miniature assembly line and its manufacturing method

Abstract

The invention discloses a miniature installing line and a manufacture method thereof. The miniature installing line comprises a conductor which is a flat conductor. A silver coating is plated outside the conductor, and an aluminum coating is arranged outside the silver coating. An insulation layer made of 125-DEG C irradiation crosslinking low smoke zero halogen polyolefin insulation material is extrusion molded outside the conductor. The silver coating and the aluminum coating are arranged outside the conductor by means of a plurality of types of process, and the insulation layer is extruded through an extruding mold with a ceramic heat preservation layer material and irradiation-crosslinked to manufacture finished products of cables. The miniature installing line and the manufacture method improves comprehensive performance of the cables, is high in space utilization rate in an installing and paving process and small in bent radius, and improves the whole attractiveness.

Description

technical field [0001] The invention relates to electric wires and cables, in particular to a miniature installation wire and a manufacturing method thereof. Background technique [0002] The traditional installation line uses round copper wire twisted as the conductor, and is insulated with polyvinyl chloride, and the general temperature resistance is -20°C to 70°C. There are also installation wires that are used in special environments and have temperature requirements, but limited by the temperature grade of the insulating material used, the operating temperature is only -40°C to 105°C. The finished installation wire is cylindrical, and the bending radius is limited by the diameter of the conductor monofilament. The conventional product is 8 times the diameter of the wire, and the flexible product can reach 6 times the outer diameter of the wire. In addition to the round shape, the traditional installation wire also has a flat shape. This kind of flat installation wire ...

AI Technical Summary

Problems solved by technology

[0003]The traditional installation line sticks under the high temperature of 110 ℃ ~ 150 ℃, which is easy to cause technical problems of safety accidents; the cable takes up a large area when laying; the cable During the processing, the oxidation rate of the conductor reached 8%, which greatly shortened the service life of the conductor; during the extrusion process of the cable insulation layer, the insulation sheath material and the inner wall of the extrusion mold cavity were prone to adhesion, which easily caused the insulation layer The smoothness of the outer wall decreases, and bubbles are generated; the bending radius of the conductor is low; the temperature resistance level of the cable is generally around 70°C. In addition, the physical properties of the cable are relatively poor, which cannot meet the needs of the actual use environment.
