As a dedicated manufacturer, Jinhua Dika Electrical Equipment Co., Ltd. specializes in providing robust and reliable power solutions for demanding industrial environments. Our 800kVA and 1000kVA Cast Resin Dry Type Transformers are engineered specifically for the rigorous power supply needs of mining equipment. We understand that downtime in mining operations is costly, which is why our transformers are built with a focus on safety, durability, and minimal maintenance, ensuring your critical operations run smoothly and efficiently.
These transformers are designed to handle the challenging conditions often found in mining applications, offering a safe and efficient alternative to traditional oil-filled units. The cast resin encapsulation provides superior protection against moisture, dust, and corrosive atmospheres, making them ideal for both indoor and outdoor installations near mining sites. With over a decade of experience and a commitment to quality certified by multiple international standards, we deliver products that power productivity and safety.
Core Features & Technical Advantages:
- Enhanced Safety & Environmental Friendliness: Being dry-type and non-flammable, these transformers eliminate the risk of fire and oil leakage, protecting personnel, equipment, and the environment. They are perfect for installations where fire safety is a paramount concern.
- Superior Insulation & Durability: The high-voltage and low-voltage windings are completely encapsulated in epoxy resin under vacuum pressure. This process creates a solid, monolithic block that is highly resistant to thermal cycling, mechanical stress, moisture, and chemical contaminants.
- Low Maintenance & High Reliability: With no liquid dielectric to monitor, filter, or replace, maintenance requirements are significantly reduced. The sealed design prevents dust ingress and protects against condensation, ensuring long-term, trouble-free operation.
- Excellent Short-Circuit Strength: The robust resin-encapsulated windings offer high mechanical strength, enabling the transformer to withstand the high electromagnetic forces generated during short-circuit events without damage.
- Low Noise Level: Advanced design and construction techniques result in low sound levels, contributing to a better working environment, which is especially valuable in noise-sensitive areas.
- High Overload Capacity: Designed with Class F or H insulation systems, these transformers can handle temporary overloads commonly encountered in mining operations, providing an extra margin of safety and operational flexibility.

Frequently Asked Questions (FAQ):
-
Q: Why choose a cast resin dry-type transformer over an oil-filled one for mining?
A: Cast resin transformers are inherently safer as they are fire-resistant and eliminate oil leakage risks. They are also more resistant to harsh, dusty, and humid environments common in mining, require less maintenance, and allow for installation closer to the load. -
Q: Can this transformer be used outdoors at a mining site?
A: Yes, absolutely. With a suitable protective enclosure (achieving IP23 or higher), these transformers are designed to withstand outdoor conditions. The resin encapsulation itself provides excellent protection against moisture and contaminants. -
Q: What is the typical delivery lead time for an 800kVA unit?
A: Lead times vary based on order specifications and current production schedule. For standard designs, it is typically within a few weeks. We recommend contacting our sales team with your detailed requirements for an accurate delivery estimate. -
Q: Are custom voltage ratios and vector groups available?
A: Yes, customization is a key service we offer. We can manufacture transformers to match your specific primary and secondary voltage requirements, as well as the necessary vector group (e.g., Dyn11, Yyn0) for your power system. -
Q: How does the cooling system work, and is forced cooling noisy?
A> Standard cooling is Air Natural (AN). For higher loads or compact spaces, Air Forced (AF) cooling with fans can be provided. Our fans are selected for efficiency and low noise operation to maintain acceptable sound levels. -
Q: What kind of warranty and after-sales support do you provide?
A: We provide a standard warranty on our transformers. More importantly, we offer comprehensive technical support, including installation guidance and documentation. Our products are shipped from major ports like Shanghai and Ningbo for efficient logistics. -
Q: Is the transformer compatible with harmonic-rich loads from variable speed drives used in mining?
A> Our transformers are designed with consideration for modern electrical environments. For applications with significant harmonics, we can provide designs with derated capacity or special features like K-factor ratings upon request to ensure reliable performance. -
Q: Do you provide complete installation services?
A: We primarily supply the transformer unit. However, we can provide detailed installation manuals, drawings, and technical consultation. We may also be able to recommend qualified installation partners in your region upon request.
