  • Patent number: 9960519
    Abstract: The present invention relates to electric equipment technology, and more particularly to an electric structure used in various devices of electric equipment. The electrode structure body with electric-shock prevention function is connected to a power transmission and distribution path to electric equipment. The electrode structure body with electric-shock prevention function prevents electric shock when the electric equipment connected to the electrode structure body or other equipment electrically connected thereto at a near place is submerged.

  • Publication number: 20150198931
    Abstract: An apparatus for limiting an interphase current and a leakage current of flooded electrical installations. More specifically, provided is the apparatus, when electrical installations are flooded in water, vapor, and other liquids which have high electrical conductivity, for preventing the electrical installations from being damaged after an interphase current, between both power lines in the electrical installations, rapidly increases through the liquids with high electrical conductivity, or preventing an electric shock accident by limiting a leakage current flowing into the earth through the liquid on both power lines. To this end, the apparatus provides a phase wire portion, an insulation barrel, a barrel-shaped wire, and a housing ground.
