200KVA 300KVA 500KVA 3 Phase Oil Transformer prices

Phase differentiation
It can be divided into three-phase transformers and single-phase transformers. In three-phase power systems, three-phase transformers are generally used. When the capacity is too large and limited by transportation conditions, three single-phase transformers can also be used to form a transformer group in three-phase power systems.

Winding differentiation
It can be divided into dual winding transformers and triple winding transformers. Usually, transformers are double winding transformers, which have two windings on the iron core, one is the original winding and the other is the secondary winding. A three winding transformer is a transformer with a larger capacity (above 5600 kVA) used to connect three different voltage transmission lines. In special cases, there are also Satons transformers that use more windings.

Structural classification
It can be divided into core type transformers and shell type transformers. If the winding is wrapped around the iron core, it is an iron core transformer; If the iron core is wrapped around the periphery of the winding, it is an iron shell transformer. The two are only slightly different in structure and have no essential difference in principle. Power transformers are all iron core type.

The transformer mainly consists of an iron core, winding, oil tank, conservator, insulating sleeve, Tap Changer, and Gas Relay.
