A multistage type electric pole for a power transmission and distribution is provided to exchange only a damaged part when the damage is generated by using an assembly member. A multistage type electric pole for a power transmission and distribution is provided to an electric pole bottom unit(200), a middle connection unit(100), an insulator installation arm unit(700), an insertion unit(800), and an electric pole upper unit(500). A lower part of the electric pole bottom unit is fixed on a ground. A plurality of grooves are formed on an upper plane of the electric pole bottom. A circular groove coupled to the other member is formed on a center of the upper plane of the electric bottom unit. The middle connection unit is assembled on the electric pole bottom unit. A lower part of the middle connection unit is coupled and fixed to the electric pole bottom unit. A circular groove coupled to the other member is formed on a center of the upper plane of the intermediate connection unit. An insulator installation arm unit is coupled to the electric pole bottom unit and the middle connection unit. The insertion unit is coupled to the electric pole bottom unit and the middle connection unit. The electric pole upper unit is assembled on the middle connection unit. A lower part of the electric pole upper unit is coupled and fixed to the middle connection unit. An upper part of the electric pole upper unit is formed as one of a dome type or a corn type. |
