4.1 Protection Enclosure
Protection enclosure can be made of general steel plate,stainless steel plate or aluminum alloy materials. For example, protection enc losure of IP20
can prevent solid object which is 12mm from entering, and this type is suitable for indoor installation. Protection enclosure of IP23 inherits the
characters of IP20 enclosure and can prevent water dropping at an angle within 60 to the vertical line from inflooding, as we ll wh ich is a dapt ed t o
outdoor installation.

4.2 Temperature Control Device
Transformer temperature control protection device adopts double-sensor principle of PTC nonlinearity resistance and PT100 linearity resistance. It has
functions of LED temperature display,temperature setting. It can k eep highes t temperat ure data, automatically alarm and trip signal and start / stop
the fan either automatically or manually. Various special temperature devices can be equipped according to the demand of the customer.
4.3 Air Cooling System
Usually, the cooling system of transformer is natural air cooling(AN),then the transformer can continuously operate at rated power. Cooling system
can be provided according to customers' requirements. The fan is controlled automatically by the temperature controller to ensure the normal

7.3 Amorphous Alloy Core Dry-type Transformer
7.3.1 General
Application: applicable for all places where common dry-type transformers are used, such as high-rise
buildings, commercia l centers, airports, oil platforms, subways, tunnels, airports, railway stations, industrial
and mining enterprises and power plants. It is especially suitable for places which are flammable an d
explosive.
