dry cast resin transformer introduction
Dry-type transformers are different from oil-immersed transformers. Their windings and iron cores are not immersed in insulating oil but use air or other gases as the insulation and cooling media. This design endows dry-type three-phase double-winding distribution transformers with advantages such as fire prevention, explosion prevention, no pollution, and simple maintenance. They are suitable for places with high requirements for safety and the environment, such as urban power grids, high-rise buildings, hospitals, schools, etc.

125 KVA 10 KV Medium Voltage Dry Type Transformer details
Basic structure
1.Iron Core: Stacked by silicon steel sheets, the iron core serves as the core component of the cast coil transformer's magnetic circuit system, playing a crucial role in guiding the magnetic flux.
2.Windings: Divided into high-voltage and low-voltage windings, these are separately wound around the iron core. Through electromagnetic induction, they enable the conversion and transmission of electrical energy.
3.Insulating Cylinder: Positioned between the high- and low-voltage windings, the insulating cylinder primarily enhances electrical insulation performance, ensuring the safe and stable operation of the three phase dry type transformer.
4.Pads: Pads are used to support and restrain the windings, maintaining their structural stability and preventing displacement or deformation during operation.
5.Fasteners: Responsible for connecting and securing all parts of the dry type distribution transformer, fasteners have anti-loosening properties, guaranteeing the structural reliability of the equipment during long-term operation.

How to form a three-phase transformer with three single-phase transformers
To form a three - phase 125 KVA 10 KV medium voltage dry type transformer with three single - phase transformers, follow these steps:
Connection on the input side: Connect the input terminals of the three single - phase transformers to the three phases of the power supply respectively. Ensure that the phase sequence is correct, usually corresponding to A, B, and C phases.
Output side connection: There are two common connection methods for the output side.
Star (Y) connection: Connect one end of each single - phase transformer's secondary winding together to form the neutral point. Then, the other three ends are the three - phase output terminals.
Delta (Δ) connection: Connect the end of one single - phase transformer's secondary winding to the start of the next one in sequence, forming a closed loop, and the connection points are the three - phase output terminals.
Ensure balance: Make sure the output voltages of the three single - phase transformers are equal. If necessary, adjust the magnetic core saturation or tap positions of the step down and step up distribution transformers to achieve voltage balance.
