Abstract
Disclosed are an insulated electric wire with partial discharge resistance and a composition for manufacturing the same. The insulated electric wire with partial discharge resistance according to the present invention includes 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. The insulated electric wire with partial discharge resistance of the present invention may be useful to prevent occurrence of cracks caused by winding of an insulated electric wire since the insulated electric wire has a sufficient partial discharge resistance and also enhances sufficient physical properties such as flexibility, pliability, bendability, elongation, etc. to maintain an electrically insulating property intactly by dispersing a stress, applied from an external force, by means of a rubber component attached to an end thereof.
