Ground-mounted Distribution Transformers

Ground distribution transformers, in the standard version they are three-phase sealed, free breathing, with/without conservator type and can be installed both outdoors and indoors.

Flexible corrugated tank walls or radiators allow adequate cooling of the transformer and compensate for changes in oil volume due to temperature changes during operation.

Larger ground-mounted transformers can also be equipped with on-load tap-changers (OLTC).

Product scope

Rated power: up to 10,000 kVA

Rated voltage: up to 36 kV

Cooling type: ONAN / ONAF

Available fluids: mineral oil and ester fluids (natural and synthetic)

Ground-mounted distribution three-phase transformer

Types of Distribution Transformers

Single Phase:

A single-phase transformer works on a single-phase power supply and contains a single winding on the primary and secondary sides. They are mainly employed in single-phase electrical power networks.

Three Phase:

A 3-phase transformer works on a three-phase power supply, and both primary and secondary windings have three sets of windings. This is a more expensive method, and it is applied in the high-voltage power network.

Pad Mounted:

The term 'Pad mount Transformer' has become a generic expression for a low kVA ground-mounted transformer with its protection and even switching options. These transformers are connected to underground utility distribution lines.

Pole Mounted:

The pole-mounted transformers are mounted on a power pole at the height of the overhead cables. These transformers are widely used in rural areas, ranging from 16 kVA to 100kVA. They are small in size and easy to mount on single-pole structures.

The Complete Guide to Ground Mounted Transformer

Padmount transformers have not been around for as long as the other types of Ground-mounted distribution transformers. Its demand is much less as well, but this does not mean that Ground Mounted Transformers are not worth considering.

Cooper Pad-Mounted Transformers have their own functions, mechanisms, and performance level. In fact, they are primarily used for advanced purposes that other distribution transformers cannot perform.
