As a specialized manufacturer with ISO9001-certified processes, Jinhua Dika Electrical Equipment Co., Ltd. designs and produces high-performance Power Electronic Coils that are integral to the reliable operation of medium to high-power frequency converters. Our coils, engineered for the demanding range of 400KVA to 1500KVA with a robust 132KV output, are built to deliver stable power conversion, minimize energy loss, and ensure the longevity of your critical drive systems. With a commitment to precision and durability, we supply components that meet the rigorous demands of global markets, from industrial automation to renewable energy infrastructure.
Our Power Electronic Coils are the heart of frequency converters, responsible for energy storage, filtering, and voltage transformation. Key features and technical specifications include:
- Precision Engineering for High Power: Each coil is meticulously wound and impregnated to handle the high currents and voltages associated with 400KVA-1500KVA applications, ensuring consistent magnetic performance and thermal stability.
- Superior Insulation System: Utilizing H-class or higher insulation materials (withstanding temperatures up to 180°C), our coils offer exceptional resistance to electrical stress and thermal aging, crucial for 132KV output reliability.
- Advanced Core Technology: We employ high-grade silicon steel or optional amorphous alloy cores to achieve low core loss and high saturation flux density, directly contributing to enhanced converter efficiency.
- Robust Mechanical Construction: The coils are securely potted or cast to resist vibration, moisture, and environmental contaminants, ensuring dependable operation in harsh industrial settings.
- Custom-Designed Compatibility: Understanding that converter designs vary, we offer extensive customization in dimensions, terminal configurations, and mounting styles to seamlessly integrate with your specific system.
The technical advantages translate into concrete benefits for your operations:
- Enhanced System Efficiency: Low-loss design reduces operational costs and improves the overall energy efficiency of the frequency converter.
- Increased Reliability & Uptime: High-quality materials and construction minimize the risk of coil failure, leading to reduced maintenance and higher system availability.
- Extended Equipment Lifespan: Superior thermal management protects the coil and surrounding components, prolonging the service life of your entire converter unit.
- Optimized Performance: Stable inductance and current handling ensure smooth motor control, precise speed regulation, and improved power quality.

Frequently Asked Questions (FAQ)
Q1: What is the primary function of this coil in a frequency converter?
A: This power electronic coil acts as a key inductive component, primarily used for filtering harmonic currents, smoothing the output waveform, storing energy, and sometimes facilitating voltage transformation within the converter circuit, ensuring clean and stable power delivery to the load.
Q2: Can you provide coils for converter models outside the 400KVA-1500KVA range?
A: Yes, we specialize in custom designs. While 400KVA-1500KVA is a common range, we can engineer coils for both lower and higher power ratings based on your detailed specifications and application needs.
Q3: How do you ensure the coil can handle the 132KV output voltage safely?
A> Safety is paramount. We employ advanced insulation materials (e.g., H-class), precise winding techniques with proper spacing (creepage and clearance), and thorough vacuum pressure impregnation (VPI) processes to eliminate voids and ensure complete dielectric integrity for high-voltage endurance.
Q4: What are the advantages of using an amorphous alloy core versus a silicon steel core?
A: Amorphous alloy cores typically exhibit significantly lower core loss (hysteresis and eddy current losses), which can lead to higher converter efficiency, especially at higher frequencies. However, they may have different cost and mechanical properties. We can advise on the best material choice for your efficiency targets and budget.
Q5: What information do you need from me to provide a custom coil quotation?
A: To provide an accurate quote and design, we typically require: the converter's full power rating (KVA), required inductance value, detailed electrical connection diagram, physical space constraints (max dimensions), cooling method available, and any specific industry standards the coil must meet.
Q6: What is your typical lead time for production?
A: Lead time depends on the order quantity and complexity. For standard designs within the specified range, production can often be completed within 4-6 weeks. Custom designs may require additional time for engineering and prototyping. We provide a firm timeline upon finalizing specifications.
Q7: Do you perform testing on finished coils before shipment?
A> Absolutely. Our quality control includes routine tests such as turns ratio test, insulation resistance test (Megger), high-potential (Hi-Pot) test at elevated voltages, and inductance measurement. Full test reports can be provided upon request.
Q8: How does your ISO9001 certification benefit me as a buyer?
A: Our ISO9001 certification demonstrates a systematic approach to quality management throughout design, procurement, manufacturing, and testing. This translates into consistent product quality, traceable processes, and a reduced risk of defects, giving you greater confidence in the reliability of our components.
