Electromagnetic shielding composite resin composition and high-voltage shielded wire comprising same

A high-voltage shielded wire comprising:

• a core composed of a conductive material;
• an insulation layer enveloping the core;
• an electromagnetic shielding layer surrounding the insulation layer and employing an electromagnetic shielding composite resin composition;
• and
• a coating layer covering the electromagnetic shielding layer and composed of an insulation material,
• wherein the electromagnetic shielding composite resin composition contains a thermoplastic resin, a metal-coated carbon fiber, carbon black, a carbon nanotube, and an additive, and
• wherein the thermoplastic resin comprises a polyurethane,
• wherein the additive contains an antioxidant, and
• wherein the antioxidant contains any one or more of a phenol-based compound or a thioether-based compound,
• wherein the carbon fiber has a diameter of 4 μm to 10 μm,
• wherein the carbon nanotube has an aspect ratio of 100 to 1,000, and wherein the metal-coated carbon fiber is coated with a multi-layer metal comprising nickel and copper.
