European box type transformer has independent transformer chamber. It is composed of transformer, automatic
temperature control system, lighting system and guard rail.
When transformer is running,lots of heat will be born. So, heat dissipation and ventilation are key for consideration.
Especially, in hot weather, temperature inside goes up faster.Rilable and safe working for transformer can not be only
reply on natural ventilation.Now European box type transformer adopts temperature sensing protection which force heat to
be out of chamber.
