The main application for a core type transformer is to increase voltage from a standard 240v supply up to 415v instead of using a 3 phase supply.
With the possible exception of a variable reluctance transformer, you should always avoid core saturation of any type of transformer. When saturated the magnetic characteristics of the core material is radically changed and the coupling coefficients will be very different. Additionally, many transformers can overheat and be damaged.
why should we use pulse transformer rather than ordinary transformer
i think Transformer operates AC and ferrite core operates in DC
Actually it depends on the air gap between the core and the windings of the transformer. This is the reason why stepped core is used in medium and large transformers as it decreases the air gap between the windings and the core of the transformer.
The container the transformer core and windings are placed inside is the tank.
A 'core type' transformer core is one in which the primary windings and secondary windings are placed around each of the limbs, as opposed to a 'shell type' core, in which the two windings are placed across the centre core. A core-type core is a magnetic circuit equivalent to an electric series circuit, whereas a shell-type core is equivalent to an electric parallel circuit. This is better answered with a diagram, so I suggest that you do a search on the internet.
Core transformer and shell transformer - it has a one window. - it has a two windows. - less mechanical protection - better mechanical protection to the coils. to the coils. -windings encircles the core. - core encircles the winding. - cylindrical windings are used. - sandwich type windings are used. - it is easy to repair. - it is not easy to repair.
shell type core can be used
500w iron core transformer .that kind of size
Transformers can have a shell type or core type core. If the core surrounds the windings, it is probably a shell type. If it does not, it is a core type. If you update this answer with an email address, or leave a message on my message board I can send you some drawings that explain this better than words can.

It is the current transformer core meant for metering.

The difference is between how the windings relate to magnetic material around which they are wound. If this magnetic material surrounds the windings then the device is said to be a shell type transformer. If the windings cover the exterior of the magnetic material then the transformer is said to be of the core type. Please see the link.

A dry type using air to cool instead of oil.
AL means transformer core property
