As a dedicated manufacturer, Jinhua Dika Electrical Equipment Co., Ltd. specializes in producing high-quality Three-phase Medium Voltage Cast Resin Transformers. Our 800kva and 1000kva models are engineered to deliver a reliable and stable power supply for demanding industrial and commercial applications. With a commitment to excellence backed by a comprehensive quality management system, we provide transformers that combine advanced insulation technology with robust construction, ensuring safety, longevity, and minimal maintenance for your operations.
Our cast resin transformers offer significant advantages over traditional oil-filled units. The core of our product's value lies in its dry-type, non-flammable design, which eliminates the risks associated with oil leaks and fires, making it ideal for installations in environmentally sensitive areas or buildings with strict safety codes. The epoxy resin encapsulation provides excellent moisture and chemical resistance, protecting the windings and ensuring consistent performance even in harsh conditions.
Key Product Features & Technical Specifications:
- Advanced Insulation System: The windings are fully encapsulated in high-grade epoxy resin under vacuum, creating a solid, homogeneous insulation barrier that is resistant to thermal cycling, moisture, and partial discharges.
- High Efficiency & Low Losses: Designed with high-quality conductive materials and optimized magnetic circuits to achieve low no-load and load losses, contributing to energy savings over the transformer's lifespan.
- Excellent Thermal Performance: The cast resin design allows for efficient heat dissipation. Optional forced air cooling (AF) is available for higher capacity models or applications requiring overload capability.
- Environmental Safety: Being a dry-type transformer, it contains no liquid dielectric, posing no risk of soil or water contamination. It is also fire-resistant and does not require special fire protection systems in many installations.
- Low Maintenance: The sealed, solid insulation system is virtually maintenance-free. There is no need for periodic oil testing, filtration, or replacement, reducing long-term operational costs.
- Flexible Configuration: Available in standard 800kva and 1000kva ratings, with customization options for specific voltage ratios, tap settings, and enclosure designs (e.g., IP23 for outdoor protection).

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of a cast resin transformer over an oil-filled one?
A: The primary advantage is safety and environmental friendliness. Cast resin transformers are dry-type, non-flammable, and contain no oil, eliminating risks of fire, leakage, and contamination. They are ideal for indoor, urban, or sensitive environmental installations. -
Q: Can this transformer be used outdoors?
A: Yes, with appropriate enclosure protection. Standard units are suitable for indoor use. For outdoor installation, an enclosure with a higher IP rating (e.g., IP23) to protect against rain and dust can be provided. -
Q: What is the typical service life of this transformer?
A: With proper application and ambient conditions, cast resin transformers have a long service life, often exceeding 25-30 years, thanks to their robust, sealed insulation system that degrades very slowly. -
Q: Are custom voltage ratios available?
A: Absolutely. While we offer standard models, we can customize the primary and secondary voltage ratios to match your specific grid requirements. Please provide your voltage specifications during inquiry. -
Q: How is the transformer cooled, and can it handle overloads?
A: The standard cooling is Air Natural (AN). For applications requiring occasional overloads or higher continuous capacity, an Air Forced (AF) cooling system can be incorporated, which uses fans to enhance heat dissipation. -
Q: What certifications does the product have?
A> Our manufacturing processes are governed by a comprehensive quality system including ISO9001. The transformers are designed to meet international electrical standards such as IEC. Specific certification marks for the final product can be discussed based on your market requirements. -
Q: What is the delivery time for an 800kva or 1000kva unit?
A: Delivery time depends on the order configuration and current production schedule. For standard models, typical lead times are available upon request. We have multiple shipment ports to expedite delivery. -
Q: Do you provide installation guidance or technical support?
A: Yes, we provide detailed installation manuals, wiring diagrams, and technical specifications. Our engineering team is available to offer support for integration into your power system.
