Three-Phase Distribution Transformer Market Analysis in Southeast Asia
By ZTELEC Electric Technology (Zhengzhou) Co., Ltd
1. Overview of Transformer Types and Regional Terminology
Three-phase distribution transformers in Southeast Asia are categorized into three main types, each with distinct naming conventions and applications:
| Type | Regional Names | Key Characteristics |
|---|---|---|
| Dry-Type Transformer | Air-Cooled Transformer | Non-flammable, eco-friendly, suitable for indoor use (e.g., malls, hospitals). |
| Oil-Immersed | Liquid-Filled Transformer | Robust cooling via mineral oil, ideal for outdoor/industrial zones with high loads. |
| Box-Type | Compact Substation | Integrated design for space efficiency, used in temporary power supply or urban grids. |
