A distribution transformer, commonly abbreviated as “distribution transformer,” refers to a stationary electrical device in a power distribution system that converts alternating current (AC) voltage and current based on the law of electromagnetic induction to transmit AC power. In some regions, power transformers with voltage ratings below 35 kilovolts (mostly 10 kV and below) are referred to as “distribution transformers,” abbreviated as “distribution transformer.” The facilities where these “distribution transformers” are installed are known as substations.

Africa's electricity grids are undergoing rapid modernization, with smart meters becoming essential infrastructure. Nigeria alone requires 10 million+ smart meters to reduce electricity theft and enable digital payment systems. Ceho Power supplies prepaid and smart meters from China at 30-50% cost savings compared to European manufacturers, with lead times of 15-30 days and flexible MOQ starting from 100 units.

Dry-type transformers are becoming the preferred choice for indoor power distribution in commercial buildings, hospitals, and data centers. This guide covers their applications, specifications, advantages, and how to choose the right dry-type transformer for your project.

Choosing between dry-type transformers and oil-immersed transformers is one of the most important decisions for any power distribution project. This guide breaks down every key difference to help engineers, contractors, and project managers make the right call.

As the development of new power systems accelerates, distribution transformers—as critical equipment for energy conversion—play a vital role in determining safety, energy efficiency, and operational and maintenance costs. The current market is dominated by two main categories: dry-type transformers and oil-immersed transformers. These two types differ significantly in terms of insulation and cooling, safety and environmental performance, applicable scenarios, and cost-efficiency. In accordance with the mandatory energy efficiency standard GB 20052-2024, this article provides a comprehensive analysis of the differences between these two types of equipment, offering an authoritative reference for engineering selection.
