The utility model discloses a composite color steel plate for manufacturing a housing of a box type transformer station, which comprises an inner core plate (1), wherein an upper steel plate (2) and an outer-layer steel plate (3) are sequentially covered on the upper surface of the inner core plate (1) from inside to outside, an anti-corrosion layer (4) is coated on the surface of the outer-layer steel plate (3), and a lower steel plate (5) is covered on the lower surface of the inner core plate (1). The composite color steel plate can not only prevent the emergence of corrosion, but also effectively protect equipment in the box-type transformer station.
