What Is the Price of a Single Phase Transformer?

Single-phase transformers are widely used in residential and industrial applications due to their compact structure and stable performance. But how much does a single-phase transformer cost? The answer varies depending on several factors, which we'll break down in this article.

Typical Price Range

In general, single-phase transformers are priced between USD 50 to USD 400 depending on their capacity, voltage rating, material, and design. Here's a rough breakdown:

• 1kVA–3kVA small transformers: $50–$120

• 5kVA–10kVA industrial units: $120–$220

Specialized or high-capacity transformers can cost even more based on custom requirements and manufacturing quality.

Main Factors Affecting Price

Several core factors influence the price of a single-phase transformer:

• Capacity & voltage level: Higher ratings mean higher costs.
