As a leading manufacturer, Jinhua Dika Electrical Equipment Co., Ltd. specializes in providing reliable and efficient power solutions for industrial applications. Our Dry Type Transformer, specifically engineered for CNC machine power supply, stands as a cornerstone of stable and precise manufacturing operations. Designed to convert 10kV to a stable 380V output, this 30kVA unit ensures your sensitive CNC equipment receives clean, consistent, and uninterrupted power, directly contributing to reduced downtime and enhanced production quality. We understand that the heart of modern machining lies in its power integrity, and our transformer is built to be that dependable heart.
This transformer is engineered with precision and durability at its core. Unlike oil-filled units, the dry-type design eliminates the risk of leaks and fire hazards, making it ideal for installation directly within your workshop near the CNC machines. Its advanced insulation system ensures stable performance even under fluctuating loads, a common scenario in machining environments. The robust construction minimizes electromagnetic interference, which is crucial for protecting the sophisticated electronics within your CNC controllers and drives. By choosing our transformer, you are not just buying a component; you are investing in the operational stability and longevity of your entire production line.
Key Technical Specifications & Advantages:
- High Efficiency & Energy Savings: Low no-load and load losses translate to significant energy cost reductions over the transformer's lifespan.
- Superior Thermal Performance: Utilizes high-quality insulating materials (Class F/H standard) that allow for safe operation at higher temperatures, ensuring reliability during continuous use.
- Low Noise Operation: Advanced core design and winding techniques result in quiet performance, contributing to a better working environment.
- Easy Maintenance & Installation: The dry-type, self-cooling design requires minimal maintenance. Its compact and versatile structure allows for flexible installation in various industrial settings.
- Robust Protection: Built to withstand voltage surges and short-circuit stresses, providing a protective barrier for your valuable CNC machinery.
For your reference, here are some of the core parameters for the standard 30kVA model:
| Parameter | Specification |
| Rated Capacity | 30 kVA |
| Primary Voltage | 10 kV (Customizable: 6kV, 11kV, etc.) |
| Secondary Voltage | 380 V (400V, 415V available upon request) |
| Frequency | 50/60 Hz |
| Vector Group | Dyn11, Yyn0, or as required |
| Insulation Class | Class F (155°C) / Class H (180°C) |
| Cooling Method | AN (Air Natural) |
| Sound Level | Typically below 55 dB(A) |
The benefits for your CNC machining operation are clear and measurable. You gain a power supply that mitigates voltage fluctuations, which are a primary cause of machine errors and component wear. This leads to improved surface finish on machined parts, tighter tolerances, and fewer rejected components. Furthermore, the transformer's inherent safety and low maintenance requirements reduce operational risks and long-term ownership costs, allowing you to focus on productivity and growth.
Frequently Asked Questions (FAQ):
-
Q: Why choose a dry-type transformer over an oil-filled one for my CNC shop?
A: Dry-type transformers are safer as they contain no flammable oil, reducing fire risk. They are more environmentally friendly, require less maintenance, and are suitable for indoor installation close to the load, minimizing power line losses. -
Q: Is this 30kVA transformer suitable for running multiple CNC machines?
A: The 30kVA rating is a common choice for a single medium-sized CNC machine or a small cluster of machines with lower power demands. It's crucial to sum the total kVA requirement of all connected equipment. We can advise on sizing for multiple machines. -
Q: Can you provide transformers with different input/output voltages?
A: Yes. While the standard model is 10kV/380V, we frequently manufacture units with primary voltages like 6.6kV, 11kV, or 13.8kV and secondary voltages of 400V, 415V, or 220V/110V for control circuits. Custom specifications are available. -
Q: How is the noise level controlled in your dry-type transformers?
A> We use high-grade, low-noise silicon steel for the core and apply secure clamping and cushioning techniques. The design focuses on reducing core magnetostriction and electromagnetic forces, resulting in quieter operation compliant with common industrial environment standards. -
Q: What is the typical delivery lead time for this product?
A> For standard specifications, the lead time is generally 15-25 working days after order confirmation. Custom-designed units may require additional time for engineering and production. -
Q: Do you offer any protection features against power surges?
A> The transformer itself provides basic isolation and impedance. For comprehensive protection against lightning strikes or severe grid surges, we recommend and can supply optional external surge protection devices (SPDs) as part of a complete power solution. -
Q: What are the installation requirements for this transformer?
A> It requires a clean, dry, well-ventilated indoor space with sufficient clearance around it for air circulation. A solid, level foundation is necessary. We provide detailed installation manuals, and our technical team is available for guidance. -
Q: How does your company ensure product quality?
A> Jinhua Dika operates a stringent quality management system. Every transformer undergoes rigorous routine tests (including turns ratio, resistance, insulation resistance, and no-load/loss tests) before shipment to ensure it meets design specifications and performance expectations.
Backed by Jinhua Dika's commitment to quality, evidenced by our management system certifications and an annual export value reflecting global trust, this Dry Type Transformer is more than just a product—it's a partnership for reliable power. With a dedicated team of 11-50 professionals and established supply chains through major ports like Shanghai and Ningbo, we efficiently serve markets from North America to Southeast Asia. We invite you to enhance your CNC operations' precision and reliability. Contact us today to discuss your specific requirements or to request a detailed quotation for this stable and efficient 30kVA power solution.
