PURPOSE: A hydroelectricity transformer having laminating structure is provided to reduce an installation area by installing vertically an automatic section switch portion, a power meter portion, and a load transformer within a case. CONSTITUTION: An automatic section switch portion(100) is formed with an automatic section switch(110), a power fuse(120), and an arrester(130). A transformer(500) is installed at a lower portion of the automatic section switch portion(100). The transformer(500) is formed with a transformer fuse(510), a meter transformer(520), and a volt meter transformer(530). A high voltage current circuit breaker(600) is formed with an over-current relay, an over-current grounding relay, and an over-voltage grounding relay. A power fuse switch portion(800) includes a plurality of cut out switches(810,810a) connected to a plurality of heads(820,820a) in order to protect the transformer. A plurality of load transformers(900) includes a head(910), a transformer(920), and a low pressure line(930).
