The invention relates to hot press complete equipment for a big width insulating carboard for a transformer, aiming at the defects of the existing equipment of inefficiency in board loading, poor reliability, generation of metal abrasive dust in the loading and unloading processes of boards and poor insulating property of products. In the invention, an insulating carboard pre-loading machine and a board loading machine are connected into a board loading unit by an upper cross beam and a lower cross beam; the board loading unit and an insulating carboard multilayer hot press are fixed togetherby one ends of the upper cross beam and the lower cross beam; trolleys in each layer of the belt trolley board loading machine without a backing board are corresponding in position to the hot pressboards in the corresponding layer of the hot press; and a vacuum chuck type board unloading machine is connected with the other end of the hot press through a stand IV. The hot press complete equipment greatly improves the efficiency and reliability of board loading, and generates no metal abrasive dust in the board loading process.
