<p>The present invention relates to an electric wire including a nonconducting substance core which has light weight and low costs, prevents the generation of deformation such as bending and distortion due to the elasticity of a nonconducting substance, and prevents the warpage of a power cable between poles in the summer by manufacturing the cable to surround a wire with the nonconducting substance made of copper and locating the nonconducting substance in the center part of the wire. The power cable including the nonconducting substance core according to the present invention includes a core part which has a circular cross section and is made of the nonconducting substance; a conducting part surrounding the core part; and a coating part which is made of the nonconducting substance and surrounds the conducting part.</p> |
