As a dedicated manufacturer with over a decade of experience, Jinhua Dika Electrical Equipment Co., Ltd. specializes in producing high-performance electrical equipment for global markets. Our Reliable 30kVA Dry Type Transformer is engineered to meet the rigorous demands of modern power transmission networks. Designed with safety, efficiency, and longevity in mind, this transformer eliminates the risks associated with liquid-filled units, making it an ideal choice for indoor installations, sensitive environments, and applications where fire safety is paramount. We combine robust manufacturing with comprehensive installation support to ensure your project's success from delivery to commissioning.
This transformer represents a significant advancement in power distribution technology. Its core features and benefits are detailed below:
- Enhanced Safety & Environmental Friendliness: As a dry-type transformer, it uses air or cast resin for cooling and insulation, completely eliminating flammable oil. This design drastically reduces fire hazards and environmental contamination risks, allowing for installation in populated buildings, hospitals, schools, and commercial complexes without special vaults or containment systems.
- Superior Reliability & Low Maintenance: The absence of liquid dielectric fluid means no leaks, no need for periodic oil testing, and no filtration systems. The solid insulation system is highly resistant to thermal aging and moisture ingress, ensuring stable performance over a long service life with minimal operational costs.
- High Efficiency & Energy Savings: Constructed with high-grade magnetic steel cores and precision-wound coils (copper or aluminum available), our transformer minimizes no-load and load losses. This high efficiency translates directly into lower electricity costs and a reduced carbon footprint for your operations.
- Robust Construction & Durability: The windings are vacuum-encapsulated in a Class F or Class H resin, providing excellent mechanical strength, protection against corrosive atmospheres, and high resistance to short-circuit forces. The enclosure typically meets IP20 protection, with options for higher ingress protection ratings upon request.
- Flexibility & Customization: We understand that power systems vary. Therefore, primary and secondary voltage ratings, vector groups (e.g., Dyn11, Yyn0), tapping options, and accessory packages (like temperature controllers, protective cages) can be customized to fit your specific grid requirements and application.
- Comprehensive Installation Support: Our service extends beyond the product. We provide detailed installation manuals, wiring diagrams, and can offer on-site technical guidance to assist your team with placement, connection, and initial testing, ensuring a smooth and correct setup.

Frequently Asked Questions (FAQ)
Q1: What are the main advantages of a dry-type transformer over an oil-filled one for power transmission?
A: Dry-type transformers offer superior safety as they are non-flammable and eliminate the risk of oil leaks and fires. They are environmentally friendly, require less maintenance (no oil testing/filtering), and are ideal for indoor installations in buildings, tunnels, and sensitive areas due to their clean operation.
Q2: Is the 30kVA rating sufficient for my application? How do I determine the right size?
A: The 30kVA rating is suitable for various applications like small commercial buildings, telecom shelters, or as a distribution transformer in a larger network. To determine the correct size, calculate your total connected load (in kVA), consider future expansion, and factor in a safe operating margin (typically 20-25%). Our technical team can assist you with this selection.
Q3: What does the included "Installation Support" entail?
A: Our installation support includes providing comprehensive technical documentation (installation manuals, drawings, test reports), and upon request, we can arrange for an engineer to offer on-site or remote guidance for unpacking, positioning, electrical connections, and preliminary functional checks to ensure proper installation.
Q4: Can this transformer be customized for different voltage levels or special requirements?
A: Yes, customization is a key strength. We can manufacture transformers with specific primary and secondary voltages (e.g., 11kV/400V, 33kV/480V), different vector groups, with or without tap changers, and with various accessory packages like IP54 enclosures, temperature monitoring systems, or protective barriers.
Q5: What are the standard delivery lead times for this product?
A: For standard 30kVA configurations, the lead time is typically 4-6 weeks after order confirmation. For customized units, the lead time may extend to 6-8 weeks depending on the complexity of the requirements.
Q6: What international standards does this transformer comply with?
A: Our transformers are designed and tested in accordance with major international standards such as IEC 60076-11 for dry-type transformers and ANSI/IEEE C57.12.01 for general requirements. They are suitable for global markets, including North America, Europe, and Asia.
Q7: What is the expected operational lifespan of this dry-type transformer?
A: With proper installation and operation within its rated parameters, a well-manufactured dry-type transformer like ours can have an operational lifespan exceeding 25-30 years. The solid resin insulation system is highly durable and resistant to degradation.
Q8: Do you provide after-sales service and warranty?
A: Yes, we offer a standard warranty period, typically 12-24 months from the date of shipment. We also provide after-sales technical support for troubleshooting, spare parts supply, and maintenance advice throughout the transformer's lifecycle.
