Abstract

The present invention relates to a coated insulated wire having improved heat dissipation properties, insulation properties, flame retardancy, and lightweight properties; and a method of manufacturing the same.

First claim

The invention claimed is:

1. A coated insulated wire sequentially comprising:
a conductor coated with an adhesion enhancer;
an insulating layer;
a light shielding layer formed by braiding a metallic fiber yarn coated with an adhesion enhancer; and
a coating layer formed of a heat dissipation silicone elastomer compound.

2. The coated insulated wire of claim 1 , wherein the insulating layer further comprises the heat dissipation silicone elastomer compound.

3. The coated insulated wire of claim 1 , wherein the adhesion enhancer is formed by adding triazinethiol propenyl dimethylpolysiloxane or triazinethiol butenyl dimethylpolysiloxane.

4. The coated insulated wire of claim 1 , wherein the metallic fiber yarn is a fiber yarn coated with a metal and having a metal coating thickness of 0.01 μm to 10 μm.

5. The coated insulated wire of claim 4 , wherein the metal comprises at least one selected from the group consisting of nickel, copper, silver, gold, iron, and tin.

6. The coated insulated wire of claim 4 , wherein the fiber yarn comprises at least one selected from the group consisting of carbon fiber, fiberglass, alumina fiber, ceramic fiber, aramid fiber, and carbon nanofiber.

7. The coated insulated wire of claim 1 , wherein the metallic fiber yarn comprises 50 to 3,000 filaments each having a diameter of 1 μm to 40 μm.

8. The coated insulated wire of claim 1 , wherein the coated insulated wire is a wire for an electric vehicle.
