Abstract

The underground electricity distributions are significantly increased because of the urbanization accompanied by rural area developments. However, it has also been increased the safety accidents such as an electric shock around the handhole where the underground cables are connected to each other. This paper provides the base materials on the necessity to amend the installation regulation for securing the insulation and structure strength of handholds using the cast iron or fiberglass reinforced plastic. Article 137 in the judgement regulation for the Korea electro-technical regulation which is one of the installation regulations for handhole is amended and announced in 2017 by being based on the materials in this paper. It is expected to continually reduce the electric shock occurrence around handhole by considering the amended installation regulation.
