As a professional manufacturer, Jinhua Dika Electrical Equipment Co., Ltd. specializes in providing robust and reliable power conversion solutions for global industrial markets. Our Three-Phase Step-Down Transformer is engineered to efficiently convert 380V/480V input power to a stable 220V output, making it an indispensable component for machinery operation, factory setups, and equipment integration in regions with varying grid standards. With over a decade of experience and a commitment to quality underscored by our management systems, we deliver transformers that ensure operational safety, equipment compatibility, and long-term cost savings for your business.
This transformer is designed for durability and performance in demanding environments. Its core construction utilizes high-grade, grain-oriented silicon steel laminations, which are meticulously stacked and clamped to minimize core losses and reduce audible noise. The windings are made from electrolytic copper or aluminum conductors (available upon request), insulated with high-temperature, class-rated materials that ensure thermal stability and long service life. The entire assembly is housed in a sturdy, ventilated enclosure made from cold-rolled steel with a protective finish, offering resistance to corrosion and mechanical damage.
Key Technical Features & Advantages:
- High Efficiency Operation: Advanced magnetic circuit design and low-loss materials contribute to high energy efficiency, reducing operational costs and heat generation.
- Superior Voltage Regulation: Maintains a consistent 220V output even with fluctuations in the input voltage, protecting sensitive connected equipment.
- Robust Thermal Management: The dry-type, air-cooled design allows for natural convection cooling, eliminating the need for flammable liquids and simplifying installation in various locations.
- Flexible Configuration: Available in standard 50kVA and 100kVA ratings, with options for different tap settings, enclosures (IP ratings upon request), and mounting styles to suit specific project requirements.
- Enhanced Safety: Built with comprehensive insulation systems and protective barriers, ensuring safe operation and compliance with common electrical safety principles.

Frequently Asked Questions (FAQ):
-
Q: What is the typical application for this transformer?
A: It is commonly used in industrial settings to power machinery, CNC equipment, production lines, and other three-phase systems that require a 220V supply from a 380V or 480V grid, common in many international markets. -
Q: Is this a dry-type or oil-filled transformer?
A: This is a dry-type, air-cooled transformer. It uses air as the cooling and insulating medium, making it safer and easier to install indoors without special containment for oil. -
Q: Can the output voltage be adjusted?
A: Yes, models typically come with off-circuit tap changers on the primary side, allowing for minor adjustments to the output voltage to compensate for line variations or specific needs. -
Q: What does the warranty cover and for how long?
A: The product comes with a standard warranty that covers defects in materials and workmanship. The specific terms and duration can be confirmed upon request and are detailed in our sales agreement. -
Q: Do you provide custom designs for different kVA ratings or voltages?
A: As a manufacturer, we have the capability to design and produce transformers with customized specifications, including different power ratings, input/output voltage combinations, and enclosure types (IP ratings) to meet unique project demands. -
Q: What are the main installation requirements?
A: The transformer requires a well-ventilated, dry, and clean environment. It should be placed on a level, solid foundation with sufficient clearance around it for airflow. Installation must be performed by qualified electricians following local electrical codes. -
Q: How is the transformer packaged for export?
A: For export, the transformer is securely mounted inside a wooden crate or on a sturdy pallet, with protective covering to prevent moisture ingress and physical damage during transit. -
