As a dedicated manufacturer with over a decade of expertise in electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. is proud to present our premium 30kVA Dry Type Transformer. Engineered for reliability and safety, this transformer is designed to meet the rigorous demands of modern industrial and commercial power distribution. We understand that your operations depend on stable and efficient power conversion, which is why we back this product with a robust 5-year warranty and provide comprehensive Mill Test Reports for complete traceability and quality assurance. Trust in our commitment to delivering electrical solutions that power your success sustainably and safely.
This 30kVA Dry Type Transformer stands out for its exceptional performance and user-centric design. Unlike liquid-filled transformers, it uses advanced solid insulation, eliminating risks of leakage and fire, making it ideal for installations where environmental safety and indoor placement are priorities. Its compact and lightweight design simplifies transportation and installation, reducing overall project time and costs. The transformer operates with low noise levels and requires minimal maintenance, ensuring a reliable power supply with lower total cost of ownership over its extended lifespan.
Key Features & Technical Advantages:
- Enhanced Safety & Environmental Protection: Utilizes high-grade, flame-retardant epoxy resin or vacuum pressure impregnation (VPI) insulation. This design is self-extinguishing, emits no toxic gases, and contains no hazardous liquids like PCBs, ensuring safe operation in sensitive environments such as hospitals, schools, shopping malls, and high-rise buildings.
- Superior Reliability & Long Service Life: Constructed with high-quality copper or aluminum windings and core laminations made from cold-rolled grain-oriented silicon steel. This ensures low no-load losses, high efficiency, and excellent resistance to thermal and short-circuit stresses, leading to dependable performance under varying load conditions.
- Low Maintenance & High Efficiency: As a sealed, dry-type unit, it requires no periodic oil testing, filtering, or replacement. The advanced cooling system (AN/AF) ensures optimal heat dissipation, contributing to high energy efficiency ratings that help reduce operational electricity costs.
- Flexible Configuration & Customization: We offer a range of standard and custom options to fit your specific needs. This includes various primary and secondary voltage taps, enclosure types (IP20, IP23 for indoor/outdoor), and optional accessories like temperature control devices, protection panels, and surge arresters.
The table below outlines some standard technical specifications. Please note that parameters can be customized according to your project requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of a dry-type transformer over an oil-immersed one?
A: Dry-type transformers use solid insulation (like epoxy resin), making them safer as they are non-flammable, leak-proof, and environmentally friendly. They are ideal for indoor installations, require less maintenance, and pose no fire or contamination hazard. -
Q: What does the 5-year warranty cover?
A: Our warranty covers defects in materials and workmanship under normal operating conditions for a period of five years from the date of shipment. It includes repair or replacement of faulty components, subject to our warranty terms and conditions. -
Q: What information is included in the Mill Test Report (MTR)?
A: The MTR is a certified document that provides detailed information about the raw materials used, such as the chemical composition and physical properties of the core steel and winding conductors. It serves as proof of material quality and traceability. -
Q: Can this transformer be used outdoors?
A: Yes, with an appropriate enclosure rating. Standard units often come with an IP20 enclosure for indoor use. For outdoor installation, we can provide enclosures with higher protection ratings (e.g., IP23, IP54) to safeguard against weather elements. -
Q: Is customization available for different voltage ratings?
A: Absolutely. We specialize in providing customized solutions. You can specify your required primary and secondary voltages, frequency, vector group, impedance, and other parameters to match your local grid and application needs. -
Q: How is the transformer cooled, and what are the noise levels?
A: It is air-cooled, typically using Air Natural (AN) convection. For higher demands, Air Forced (AF) cooling with fans can be added. Noise levels are kept low, generally below 55 dB(A), making it suitable for noise-sensitive environments. -
Q: What are the typical delivery lead times?
A: Lead times vary based on order quantity and customization level. For standard 30kVA models, production typically takes 3-4 weeks. We will provide a confirmed schedule upon order confirmation. -
Q: Do you provide installation guidance or technical support?
A: Yes, we provide comprehensive installation and operation manuals with each unit. Our technical team is also available to offer remote support and guidance for installation, commissioning, and troubleshooting.
