Zhejiang Jiangshan Hengli Electrical Co., Ltd. is one of the leading manufacturers and suppliers of 3 phase utility transformer in China. If you're going to wholesale durable 3 phase utility transformer made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
This is a 3 phase utility transformer delivered to China used in public power renovation of an old residential community. The rated capacity of the transformer is 400kVA,the primary voltage of the transformer is 10kV and secondary voltage is 0.4kV. A 3 phase utility transformer is a three-phase distribution transformer specially designed for public power grid utilities, utility distribution networks and municipal power supply systems. All 3 phase utility transformers are 3 phase transformers, but not all 3 phase transformers are utility transformers. "Utility" marks it as grid-grade equipment for public power supply with unified strict industry specifications.
As a direct transformer factory, we provide a serial of reliable 3 phase utility transformers for both industrial and civil use. They are suitable for outdoor and indoor use and work effectively under the temperatures from -25°C to 40°C, stepping down high-voltage grid supply (such as 11kV, 10.5kV, 10kV, 6.3kV, 6kV) into 400V in safety for home and business usages.
Advantages of 3 Phase Utility Transformer
3 phase transformers bring multiple key merits. They support balanced three-phase loads to boost operating efficiency. Lower current effectively stabilizes output voltage and avoids severe voltage drops. With balanced loading, the equipment delivers steady power and fewer outages, cutting costly downtime. Ideal for power generation, transmission and distribution in all industrial and commercial facilities.
Difference Between 3 Phase Utility Transformer & General 3 Phase Transformer
1. Definition Scope
3 phase transformer (general term)
It is a broad umbrella word covering all three-phase transformers regardless of usage. It includes every 3-phase voltage conversion device: utility grid transformers, industrial load transformers, mining transformers, wind/solar dedicated transformers, furnace transformers, etc. It only describes the electrical structure (3-phase winding design), with no limit on application scenario.
3 phase utility transformer
It is a subcategory of 3 phase transformers. The word "utility" refers to public power utility companies (grid operators). This type is specially manufactured for municipal, urban & rural public power distribution networks.

3. Usage Scenario Distinction
General 3 phase transformer: Purchased and installed by individual factories, shopping malls or enterprises for their own private power consumption.
3 phase utility transformer: Procured by power bureaus/grid companies to supply public electricity to communities, streets and public facilities for all residents.
