WIRING SYSTEM OF PRIMARY CABLE OF POWER DISTRIBUTION TRANSFORMER

摘要

PURPOSE:To not only improve workability of inspection and repair but also improve durability of a repeater by improving environment and external appearance and preventing damage by birds. CONSTITUTION:A cylindrical accommodation body 3 is installed at the upper end of an electric pole 1 and a cutout 2 is accommodated within the cylindrical body 3. A column type transformer 4 is installed at the upper end of the cylindrical accommodation body 3 in such a manner as forming one pole with the electrical pole 1 and the cylindrical accommodation body 3. A supporting insulator 10 which supports a distribution wire 11 is supported by an arm metal 5 which is branchingly provided in the electric pole 1 and thereby the distribution wire 11 is isolated in the predetermined interval from the cutout 2 and transformer 4 on the pole 1. A high voltage drop wire 13 connecting the supporting insulator 10 and cutout 2 is led into the cylindrical accommodation body 3 through the arm metal 5 and pole 1 and the cutout 2 and transformer 4 are connected within the cylindrical accommodation body 3 with a repeating wire 14.
