The cooling method of nature oil circulation is not only widely used in small-middle type power transformer, but also used in large type power transformer with low load and low ambient temperature.
Standard transformer can only operate at the rating capacity without the cooling fan, while each transformer may be installed with an extra cooling fan to increase the output capacity.
每台产品上均可加装风机增大变压器容量输出，不装风机的变压器能在额定容量下连续运行。
