Product Description
A three-phase pad-mounted transformer is an electrical device that converts high voltage to low voltage (or vice versa). It consists of three independent but interconnected single-phase transformers, with each transformer connected to a phase line.
A three-phase pad-mounted transformer typically consists of a core and coils. The core is made up of laminated iron sheets with a high magnetic permeability, which helps conduct the magnetic field. The coils are wound with insulated wire and are separated into low-voltage and high-voltage sides. During operation, an AC power source is applied to the high-voltage side coils, generating an alternating magnetic field that induces voltage in the low-voltage side coils.
The key advantages of a three-phase pad-mounted transformer are as follows:
- Efficiency: Its three-phase structure allows for the transmission of larger power within a smaller space, improving energy efficiency.
- Stability: The three-phase operation reduces voltage fluctuations and power wastage.
- Reliability: With multiple separate transformers, if one transformer fails, the others can continue to operate, enhancing system reliability.
- Cost-effectiveness: Compared to single-phase transformers, three-phase pad-mounted transformers are more cost-effective and efficient in transmission and distribution systems.
Three-phase pad-mounted transformers are widely used in industrial and residential power systems for applications such as voltage stepping, motor starting, power transmission, and distribution.

There are two packaging methods for Daelim three-phase pad mouted transformers. One way is as shown in the picture above, Daelim transformers are packed in wooden boxes. Place the transformer on a solid wood pallet and secure it with wooden boards on top and around it. This wooden box packaging ensures that the transformer will not be damaged by impact during transportation. Another way of packaging as shown in the picture above is wooden pallet packaging. This packaging method of transformers is usually used for full container shipping by sea. After wrapping the transformer with plastic film (moisture-proof and scratch-proof), fix it on the log pallet.
