What are the advantages of single-phase transformers?

Less material usage: Single-phase transformers require 20% less iron and 10% less copper compared to three-phase transformers of the same capacity. Particularly when using a wound iron core structure, the no-load losses of the transformer can be reduced by more than 15%. This reduction in material usage leads to decreased manufacturing and operational costs, ultimately resulting in optimal life cycle costs.

Lower line investment: Implementing a single-phase power supply system in the grid can save 33% to 63% of conductors. Calculated based on economic current density, this can save 42% of conductor weight, and based on mechanical strength, it can reduce conductor consumption by 66%. Therefore, it can reduce the overall construction investment of the transmission line. This is particularly meaningful for rural and urban areas in China concerning street lighting and residential electricity consumption.

Beneficial for modern production: Due to their simple structure, single-phase transformers are suitable for large-scale modern production, which helps improve product quality and efficiency. They are also suitable for introducing new technologies, materials, and processes, gaining technological advantages. The 16th Fifth Plenary Session of the Party proposed saving resources as a basic national policy. The "Eleventh Five-Year Plan" further set about a 20% reduction in energy consumption per unit of GDP as a binding target. In this context, new products with high added value for loss reduction will have great potential.

Lower construction investment: Implementing single-phase power supply systems in lightly loaded areas can reduce construction investment. However, transforming heavily loaded areas into single-phase power supply systems requires significant economic input. Some single-phase transformers have been piloted in residential communities by converting large transformers into multiple smaller transformers installed near loads, shortening the distance of low-voltage main lines. Although this reduces line losses, it requires substantial investment, such as extending high-voltage transmission distances and increasing the number of small capacity transformers. Overseas, due to high residential electricity usage, each household or several households may use a single-phase transformer, reflecting the wealth of the country and the substantial investment by the power sector. Despite the large investment, it is still cost-effective overall.
