As a professional manufacturer, Jinhua Dika Electrical Equipment Co., Ltd. specializes in providing robust and reliable power solutions for industrial applications worldwide. Our 250 KVA Industrial Transformer for Voltage Conversion from 220V to 380V is engineered to meet the demanding requirements of modern industrial facilities, ensuring stable and efficient power distribution. With years of experience and a commitment to quality backed by comprehensive management certifications, we deliver transformers that enhance operational safety and energy efficiency for your business.
This transformer is designed to bridge common voltage gaps in industrial settings, converting standard 220V input to a higher 380V output, which is widely used for powering heavy machinery, large motors, and extensive lighting systems. Its core value lies in providing a safe, stable, and customizable power conversion solution that minimizes downtime and maximizes equipment performance.
Key Features and Technical Advantages:
- High Capacity & Robust Design: The 250 KVA rating ensures it can handle significant loads, suitable for medium to large-scale industrial plants, workshops, and manufacturing lines.
- Precision Voltage Conversion: Accurately transforms 220V AC input to a stable 380V AC output, maintaining voltage regulation within tight tolerances to protect sensitive equipment.
- Customizable Construction: Available in both oil-cooled and dry-type (air-cooled) designs, allowing selection based on environmental, safety, and maintenance preferences.
- Advanced Insulation Systems: Utilizes high-grade insulating materials and techniques to ensure long-term reliability, reduce losses, and enhance safety.
- Flexible Configuration Options: Connection types (Delta/Wye), mounting styles (pad or pole), and operating frequency (50Hz/60Hz) can be tailored to match specific regional standards and installation requirements.
- Efficient Thermal Management: Designed with effective cooling mechanisms to operate within safe temperature ranges even under continuous full load, extending service life.
- Durable Core and Windings: Uses quality copper or aluminum windings and a robust magnetic core to minimize energy losses and provide consistent performance.

Frequently Asked Questions (FAQ):
-
What is the primary use of this 250 KVA 220V to 380V transformer?
It is primarily used in industrial facilities to convert a common lower voltage supply (220V) to a higher voltage (380V) required to operate heavy machinery, large motors, industrial lighting, and other high-power equipment efficiently and safely. -
Can this transformer be used outdoors?
Yes, depending on the chosen configuration. Options include pad-mounted designs suitable for outdoor installations with appropriate weatherproofing. Specific environmental protection features can be discussed based on your site conditions. -
What are the main differences between oil-cooled and dry-type versions?
Oil-cooled transformers use insulating oil for cooling and are often used in high-capacity, continuous-duty applications. Dry-type transformers use air cooling and are preferred in environments where fire safety, lower maintenance, or indoor installation is a priority. Both types are available. -
Is the transformer compatible with both 50Hz and 60Hz power systems?
Yes. The transformer can be manufactured to operate at either 50Hz or 60Hz frequency. Please specify your regional standard during inquiry. -
What kind of efficiency can I expect from this transformer?
Under typical full-load conditions, the transformer is designed to achieve an efficiency greater than 98%, minimizing energy losses and reducing operational electricity costs. -
Does it come with any protective features or accessories?
Basic models include standard insulation and terminals. Additional protective features such as enclosures, lightning arresters, or temperature monitoring devices are available as optional accessories or can be integrated upon request. -
How long is the typical delivery time?
Delivery time depends on order specifications, customization requirements, and current production schedule. Standard configurations typically have shorter lead times. We provide estimated timelines upon order confirmation. -
Can the transformer be customized for different input/output voltages?
While this model is specifically designed for 220V to 380V conversion, our manufacturing capabilities allow for custom designs with other voltage ratios. Please contact us to discuss your specific voltage conversion needs.
