As a specialized manufacturer with over a decade of experience, Jinhua Dika Electrical Equipment Co., Ltd. is dedicated to providing reliable and efficient power distribution solutions. Our Dry-type Transformer for Voltage Conversion is engineered for safety, durability, and optimal performance in diverse electrical networks. Designed with advanced cast resin technology, this transformer eliminates fire and environmental hazards associated with liquid-filled units, making it an ideal choice for indoor installations and sensitive applications. We combine robust manufacturing under stringent quality management systems with comprehensive technical support, ensuring our products meet the precise needs of our global clientele across industries.

Core Product Features & Advantages:

Enhanced Safety & Environmental Compliance: Utilizes solid cast resin insulation, which is non-flammable and contains no oil. This design prevents risks of fire, leakage, and soil contamination, allowing for installation in populated areas, buildings, and environmentally sensitive locations without special containment measures.
Superior Reliability & Low Maintenance: The epoxy resin encapsulation provides excellent protection against moisture, chemicals, and dust, ensuring stable operation in harsh conditions. With no need for periodic oil testing or filtration, operational costs and maintenance downtime are significantly reduced.
High Efficiency & Energy Savings: Constructed with high-grade electrical steel and precision-wound coils to minimize no-load and load losses. This results in lower lifetime energy consumption, contributing to reduced operational expenses and a smaller carbon footprint.
Customizable Design & Flexible Configuration: We offer tailored solutions to match specific project requirements. Key parameters such as voltage ratio, power rating, vector group, and protection class can be customized. Optional features include temperature control systems, fan cooling for increased capacity, and various bushings.
Comprehensive Technical Support: Our service extends beyond delivery. We provide expert support covering system design consultation, installation guidance, commissioning assistance, and maintenance training to ensure optimal integration and long-term performance.

Frequently Asked Questions (FAQ)

What are the main advantages of a dry-type transformer over an oil-filled one?
Dry-type transformers use solid insulation (cast resin), making them non-flammable, leak-proof, and environmentally friendly. They require less maintenance, have no risk of oil fires or spills, and are ideal for indoor and sensitive installations.
What voltage levels can your dry-type transformers handle?
Our standard designs accommodate primary voltages up to 36kV (e.g., 11kV, 22kV, 33kV). We can engineer units for higher or specific voltage requirements based on your project specifications.
Do you provide custom-designed transformers?
Yes, customization is a key service. We can tailor power ratings, voltage ratios, impedance, vector groups, protection levels (IP ratings), cooling methods, and terminations to fit your exact application needs.
What kind of technical support do you offer with the product?
Our support package includes application engineering advice, installation layout guidance, commissioning checklists, and operational/maintenance training. We are available to assist with troubleshooting and performance optimization.
Are your transformers suitable for outdoor installation?
While primarily designed for indoor use, our transformers can be equipped with higher IP protection classes (e.g., IP23) and appropriate housing for outdoor placement. Please consult our engineers for specific environmental conditions.
What are the standard delivery terms and lead time?
We ship from major ports like Shanghai, Tianjin, Guangzhou, and Ningbo. Lead times vary based on order complexity and customization but are typically within 4-8 weeks for standard models. We offer EXW, FOB, CIF, and other Incoterms.
How do you ensure the quality and reliability of your transformers?
Our manufacturing process is governed by a certified ISO9001 quality management system. Each unit undergoes rigorous testing, including routine tests per IEC standards (ratio, resistance, impedance, dielectric) and optional special tests as requested.
Can these transformers be used with variable frequency drives (VFDs) or in harmonic-rich environments?
Yes. Our transformers can be designed with appropriate insulation classes and construction techniques to withstand the voltage stresses and harmonic loads associated with VFDs and non-linear loads. K-factor or harmonic mitigation designs are available.
