Distribution Transformer

9 May 2023

A distribution transformer enables electrical energy to be transported and made suitable for consumption. Distribution transformers allow the voltage and current levels of electrical energy generated by power plants to be modified, transforming the energy into a form that end-users can efficiently utilize. These devices make it possible to lower the voltage and deliver it to end-users, finding application in various settings, including homes, hospitals, factories, and more. Distribution transformers come in different types based on their cooling method, mainly categorized as oil-immersed (liquid-filled) or dry-type transformers. In oil-immersed transformers, insulation oil is used for cooling, while dry-type transformers do not require insulation oil. The presence of fiberglass insulation between windings aids in the cooling of distribution transformers. The cost of distribution transformers can vary depending on factors such as the quality and quantity of materials used in their production.

Distribution Transformer Features

Distribution transformer features are diverse and cater to a wide range of requirements. These products offer a broad price range, allowing you to find options that suit your needs and budget. The quality of materials used significantly impacts the cost of distribution transformers. For instance, copper or aluminum is commonly used in the winding section of transformers, but opting for aluminum in these sections can help reduce costs without compromising efficiency. Therefore, it’s essential to choose transformers that align with your expectations and offer long-term durability. Energy losses in these transformers primarily occur due to winding and cores.

Distribution Transformer Conversion

Distribution transformer conversion is an essential aspect of the electrical industry. These devices play a crucial role in converting high voltage to low voltage for distribution within power grids. They are particularly suitable for OG-AG (High Voltage to Low Voltage) conversions. Distribution transformers used for low-voltage distribution networks typically have a rating of less than 5 MVA (Mega Volt-Amperes). Compared to power transformers, they have smaller dimensions and are designed for approximately 99% efficiency throughout the day, calculated in kilowatt-hours.
