A Study on the Fabrication Method of Underground Cable with Electromagnetic Absorbing Finishing Material

摘要

The present invention relates to an underground cable protection plate having an electromagnetic absorbing finishing material, which improves the health of pedestrians by absorbing electromagnetic waves generated from extra-high voltage wires buried in the ground; and a manufacturing method therefor. The present invention comprises: a metal yarn fabric (102) formed by weaving metal yarns such as silver or gold yarns to absorb electromagnetic waves; a first fly ash panel (104) installed on the top surface of the metal yarn fabric (102) to absorb electromagnetic waves; a second fly ash panel (106) installed on the bottom surface of the metal yarn fabric (102) at a predetermined interval from the first fly ash panel (104) to absorb electromagnetic waves; a first rubber panel (108) installed on the top surface of the first fly ash panel (104) at a predetermined interval from the second fly ash panel (106), and coated with the extract of Korean Dendropanax to absorb electromagnetic waves; a second rubber panel (110) installed on the bottom surface of the second fly ash panel (106) at a predetermined interval from the first rubber panel (108), and coated with the extract of Korean Dendropanax to absorb electromagnetic waves; a first composite panel (112) installed on the top surface of the first rubber panel (108) at a predetermined interval from the second rubber panel (110), and made of a mixture of ocher powder and polymer powder to absorb electromagnetic waves; and a second composite panel (114) installed on the bottom surface of the second rubber panel (110) at a predetermined interval from the first composite panel (112), and made of a mixture of ocher powder and polymer powder to absorb electromagnetic waves.
