As a dedicated manufacturer, Jinhua Dika Electrical Equipment Co., Ltd. specializes in producing high-quality electrical components for a global clientele. Our Single Phase Transformer 15kVA 25kV is engineered for reliable performance in demanding power distribution applications. Built with premium copper windings and backed by comprehensive documentation, this transformer offers a robust solution for stepping down high voltage to usable levels with exceptional efficiency and longevity.
This transformer is designed to meet the needs of various industries, providing a critical link in electrical infrastructure. Its construction prioritizes safety, durability, and consistent operation, making it a dependable choice for utilities, industrial plants, and commercial facilities worldwide.
Core Features and Technical Advantages:
- Premium Copper Windings: Utilizes high-conductivity copper for the windings, which results in lower resistance, reduced energy losses (I²R losses), better heat dissipation, and superior overload capacity compared to aluminum alternatives.
- High Voltage Handling: Rated for 25 kV on the high-voltage side, making it suitable for connection to medium-voltage distribution lines, commonly found in utility and industrial power networks.
- Robust Insulation System: Features advanced insulation materials (e.g., Nomex, epoxy resin) capable of withstanding high thermal and electrical stresses, ensuring long-term reliability and safety.
- Efficient Cooling Design: As a dry-type transformer, it uses natural or forced air cooling, eliminating the risks and maintenance associated with liquid coolants. This makes it ideal for indoor installations or environmentally sensitive areas.
- Customizable Configurations: Available in various mounting styles (pad or pole), insulation classes (Class H, F, B), and with optional features like protective enclosures (IP ratings), taps for voltage adjustment, and temperature monitoring devices.
- Comprehensive Quality Assurance: Each unit undergoes rigorous testing, including turns ratio, insulation resistance, polarity, and induced potential tests. The provided Mill Test Report details the raw material specifications and factory test results, offering full traceability.

- Global Compliance: Manufactured with international standards in mind, facilitating easier integration into diverse regional power grids.
Frequently Asked Questions (FAQ):
-
Q: What is the primary application of this 15kVA, 25kV single-phase transformer?
A: It is primarily used in single-phase power distribution networks to step down medium voltage (25kV) from utility lines to lower utilization voltages (e.g., 120/240V or 240/480V) for residential complexes, small commercial buildings, farmsteads, and light industrial equipment. -
Q: Why are copper windings specified, and what are their advantages?
A: Copper windings offer higher electrical conductivity, better mechanical strength, superior resistance to corrosion, and higher short-circuit withstand capability. This leads to a more compact design, higher efficiency, and longer operational life compared to aluminum windings. -
Q: What exactly is included in the Mill Test Report?
A: The Mill Test Report (MTR) is a certificate from the raw material supplier (e.g., copper mill). It verifies the chemical composition, physical properties (tensile strength, conductivity), and confirms that the copper used meets specified standards, providing traceability and quality assurance. -
Q: Can this transformer be used for both 50Hz and 60Hz systems?
A: Yes, the core and winding design can be optimized for either 50Hz or 60Hz operation. It is crucial to specify your required system frequency when ordering to ensure optimal performance. -
Q: Is an enclosure available for outdoor or harsh environment installation?
A: Yes, we offer optional protective enclosures with specified IP (Ingress Protection) ratings (e.g., IP23, IP54) to shield the transformer from dust, moisture, and weather conditions for outdoor or challenging indoor environments. -
Q: What are the typical delivery lead times?
A: Lead times vary based on order quantity and customization. Standard configurations typically have shorter lead times. We provide estimated timelines upon receipt of your detailed requirements. -
Q: Do you provide installation and commissioning guidance?
A: Yes, we supply detailed installation manuals, wiring diagrams, and operation guidelines. Remote technical support is also available to assist with commissioning and troubleshooting. -
Q: Are spare parts readily available?
A: As the manufacturer, we maintain an inventory of key components and spare parts for our transformer models, ensuring availability for maintenance and repair needs.
