Abstract
A power transmission transformer (1) includes a transformer body (11). Each of two upper pipings (3) is connected between the transformer body (11) and one of two heat dissipators (2, 21) outside of the transformer body (11). Each of two lower pipings (4) is connected between the transformer body (11) and one of the heat dissipators (2, 21). A sound absorbing device (6, 61) is mounted between and spaced from one of two sidewalls of the transformer body (11) and one of the heat dissipators (2, 21). The sound absorbing device (6, 61) is fixed to one of the upper pipings (3) and one of the lower pipings (4). An outer wallboard (63) and a sound absorbing material (64) are respectively mounted to two sides of at least one fixing frame (62) of the sound absorbing device (6, 61).
