The present invention relates to a bushing for power distribution, comprising: an insulator (10) having a through hole (11) formed therein to penetrate both end parts; and a conductor rod (20) combined with the through hole (11) of the insulator (10), wherein the insulator (20) is installed on an outer enclosure (1) of a transformer. The conductor rod (20) includes: a rod part (21) combined with the through hole (11) of the insulator (10); and a terminal part (22) extending as one body to protrude from the rod part (21) out of the insulator (10) and having an external conductive line connected thereto. Provided is a bushing for power distribution having a rod and a terminal formed in one unit, wherein the rod part (21) and the terminal part (22) of the conductor rod (20) are composed of a core part (20a) composed of aluminum, and a sheath part (20b) composed of copper and enveloping the outer surface of the core part (20a). Therefore, provided are a bushing for power distribution having a rod and a terminal formed in one unit and a manufacturing method thereof, wherein logistical costs can be reduced, work convenience can be improved, conductivity can be improved and the supply of electricity is facilitated. 본 발명은 양단부를 관통하는 관통공(11)이 내부에 형성된 애자(10)와, 이 애자(10)의 관통공(11)에 결합되는 도체봉(20)을 포함하며, 상기 애자(20)가 변압장치의 외함(1)의 통공(2)에 설치되는 배전용 부싱에 있어서, 상기 도체봉(20)은 애자(10)의 관통공(11)에 결합되는 로드부(21)와, 이 로드부(21)에서 애자(10)의 외부로 돌출되도록 일체로 연장되며 외부도선이 연결되는 터미널부(22)를 포함하고, 상기 도체봉(20)의 로드부(21) 및 터미널부(22)는 알루미늄으로 이루어진 심부(20a)와, 동(銅)으로 이루어지며 상기 심부(20a)의 외부면을 감싸는 외피부(20b)로 이루어진 것을 특징으로 하는 로드와 터미널이 일체로 형성된 배전용 부싱이다.
