As a professional manufacturer with over a decade of experience in electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. proudly presents our 45kVA SG-Type Dry Transformer. Engineered for reliable three-phase power conversion from 440V to 220V, this transformer is a cornerstone solution for industrial facilities seeking safe, efficient, and maintenance-free voltage transformation. Our commitment to quality, evidenced by our ISO9001 certification among others, ensures that every unit delivers consistent performance in demanding environments, from manufacturing plants to commercial complexes.
Core Advantages & Technical Highlights:
- Enhanced Safety & Environmental Friendliness: As a dry-type transformer, it uses advanced solid insulation systems instead of oil, eliminating the risk of fire, leakage, and environmental contamination. This makes it ideal for installations indoors, in populated areas, or in environmentally sensitive locations.
- Superior Reliability & Long Service Life: The SG-Type design incorporates high-quality, class F or higher insulation materials, ensuring excellent thermal stability and resistance to moisture and chemical vapors. This robust construction translates into a long operational lifespan with minimal degradation.
- Low Maintenance & High Efficiency: With no liquid coolant to monitor or replace, maintenance requirements are drastically reduced. The optimized core and winding design minimizes no-load and load losses, contributing to overall energy savings and lower operating costs.
- Flexible Configuration & Customization: We understand that needs vary. This 45kVA model can be customized with options such as copper or aluminum windings, different IP protection levels (standard is IP20), and various tap settings to accommodate specific voltage requirements.

Benefits for Your Business:
- Operational Safety: Provides a safer working environment by removing flammable oil risks, often a prerequisite for insurance and local regulations in indoor settings.
- Space & Installation Efficiency: Dry-type transformers are generally more compact and lighter than oil-filled equivalents, offering flexibility in placement and reducing structural support needs.
- Cost-Effective Operation: The combination of high efficiency and negligible maintenance leads to significant total cost of ownership savings over the transformer's lifespan.
- Versatile Application: Perfect for stepping down voltage to power 220V three-phase machinery, control circuits, lighting systems, and other equipment in factories, workshops, hospitals, schools, and commercial buildings.
Frequently Asked Questions (FAQ):
-
Q: What is the main difference between a "dry-type" and an "oil-immersed" transformer?
A: Dry-type transformers use solid insulation (like resin or VPI) and are air-cooled, making them fire-resistant and eco-friendly for indoor use. Oil-immersed types use oil for insulation and cooling, which can be a fire hazard and require containment systems, typically used outdoors. -
Q: Can this 45kVA transformer handle single-phase loads on its secondary side?
A: Yes, a three-phase 220V output can supply both three-phase and single-phase loads. However, care must be taken to balance the loads across phases to ensure optimal performance and prevent overheating. -
Q: Is the 440V primary voltage fixed, or can it be adjusted?
A: Standard units are designed for a fixed 440V input. However, we offer customizable models with off-load or on-load tap changers to accommodate a range of input voltages, such as 415V or 480V. Please specify your requirement. -
Q: What is the expected lifespan of this SG-Type dry transformer?
A: With proper installation, adequate ventilation, and within its rated operating conditions, a well-manufactured dry-type transformer like ours can have a service life exceeding 25-30 years. -
Q: Do you provide custom enclosures or specific color options?
A: Yes. We can provide enclosures in various IP ratings (IP23, IP54, etc.) for different environmental protections. Color customization for the enclosure is also available upon request to match your facility's aesthetics. -
Q: What are the shipping and lead time details?
A: We ship globally from major Chinese ports like Shanghai, Tianjin, Guangzhou, and Ningbo. Lead times vary based on customization and order quantity but typically range from 4-8 weeks for standard models. Precise quotes are provided upon order confirmation. -
Q: Does this transformer come with any warranty?
A: Yes, we offer a standard warranty period on our transformers. The specific terms and duration will be detailed in the sales contract and are backed by our ISO9001 quality management system. -
Q: Can you assist with installation guidance or provide technical drawings?
A: Absolutely. We provide detailed installation manuals, wiring diagrams, and dimensional drawings with each shipment. Our technical team is also available for remote consultation to support your installation process.
