Patent ID: 7414202

Claim:
An insulated electric wire with partial discharge resistance, comprising: a first layer manufactured using a composition comprising an insulating base resin constituting a basic material of an insulated electric wire, and a rubbery modifier included at a content of 0.1 to 30 parts by weight on the basis of 100 parts by weight of the insulating base resin to improve flexibility of an insulated electric wire; and a second layer manufactured using the composition comprising an insulating base resin constituting a basic material of an insulated electric wire, an inorganic insulator included at a content of 5 to 40 parts by weight on the basis of 100 parts by weight of the insulating base resin, and a rubbery modifier included at a content of 0.1 to 30 parts by weight on the basis of 100 parts by weight of the insulating base resin to improve flexibility of an insulated electric wire, wherein the inorganic insulator is metal nitride having a diameter of 5 to 900 nm, which is a single material or a mixture of at least two materials selected from the group consisting of silicon (Si), titanium (Ti), zirconium (Zr) and cobalt (Co).
