As a dedicated manufacturer with over a decade of experience, Jinhua Dika Electrical Equipment Co., Ltd. is proud to present our reliable 10kVA Oil Immersed Transformer, engineered specifically for 11kV rural electrification applications. We understand the critical need for robust and efficient power distribution in remote areas, and this transformer is designed to meet those challenges head-on. Our commitment to quality, backed by comprehensive management systems, ensures a product that delivers stable performance, enhances grid reliability, and supports sustainable rural development. This transformer represents a cornerstone solution for utilities and contractors aiming to expand electricity access with dependable and durable equipment.
Core Product Features & Technical Advantages:
- Robust Construction for Harsh Environments: The core and windings are fully immersed in high-grade mineral oil, providing superior insulation and cooling. This design ensures stable operation across a wide temperature range, making it ideal for outdoor installation in varied climatic conditions common in rural settings.
- Optimized for Rural Grids: Specifically engineered for 11kV distribution networks, this 10kVA unit is perfectly sized for supplying clusters of households, small communities, agricultural pumps, and small-scale commercial establishments, effectively addressing the load requirements of rural electrification projects.
- High Efficiency & Low Losses: Utilizing advanced core steel and precision winding techniques, our transformer minimizes no-load and load losses. This translates to significant energy savings over its operational lifetime, reducing the overall cost of electricity delivery and improving the economic viability of rural power projects.
- Enhanced Safety and Reliability: The oil-filled design acts as a natural fire retardant and provides excellent arc-quenching properties. Features such as a conservator tank with a silica gel breather to prevent moisture ingress, a pressure relief device, and a thermometer well are integrated to ensure safe and reliable long-term operation with minimal maintenance.
- Flexible Configuration Options: We offer customization to suit specific project needs. Options include different tapping ranges for voltage regulation, choice of winding material (copper for higher efficiency or aluminum for cost-effectiveness), and various bushing types. Mounting configurations can be tailored for pole-top or ground-based installations.

Benefits for Your Rural Electrification Project:
- Extended Service Life: The oil immersion effectively protects internal components from oxidation, moisture, and contaminants, leading to a longer operational lifespan and reduced total cost of ownership.
- Reduced Operational Costs: High efficiency directly lowers energy losses, while the robust design minimizes maintenance frequency and costs, which is crucial for remote locations where service access can be challenging and expensive.
- Project Scalability: As a standardized yet customizable unit, it allows for easy replication and scaling across multiple villages or regions within a large-scale electrification program, ensuring consistency and simplifying logistics.
- Improved Grid Stability: Provides reliable voltage transformation and helps maintain power quality in the often-weak rural distribution networks, contributing to fewer outages and better service for end-users.
Frequently Asked Questions (FAQ):
-
Q: Is this transformer suitable for areas with extreme temperatures?
A: Yes. The oil-immersed design provides excellent thermal stability. The high-grade mineral oil and robust construction allow it to operate reliably in both high-temperature and low-temperature environments commonly encountered in rural areas. -
Q: What are the delivery and installation considerations for remote sites?
A: The transformer is designed for straightforward installation. It can be supplied as a complete, oil-filled unit ready for connection. We provide detailed installation manuals and can offer guidance. Shipping from major ports like Shanghai, Tianjin, Guangzhou, or Ningbo ensures logistical flexibility. -
Q: Can you provide transformers with different low-voltage outputs?
A: Absolutely. While 400/230V is standard for many regions, we can customize the secondary voltage to match local grid standards, such as 480V, 240V, or others, based on your specific project requirements. -
Q: What is the expected lifespan of this transformer?
A: With proper installation and routine maintenance (such as periodic oil testing), our 10kVA oil-immersed transformer is designed for a service life exceeding 25 years, making it a long-term asset for rural infrastructure. -
Q: Do you offer both copper and aluminum winding options? What's the difference?
A: Yes, both are available. Copper windings generally offer slightly higher efficiency and better mechanical strength but come at a higher initial cost. Aluminum windings provide a cost-effective solution with reliable performance, which can be advantageous for budget-conscious projects. -
Q: What kind of after-sales support do you provide?
A: As a manufacturer, we provide comprehensive support including technical documentation, spare parts availability, and troubleshooting assistance. Our experience serving markets from North America and Europe to Africa and Southeast Asia equips us to handle diverse customer needs. -
Q: Are these transformers compliant with international standards?
A: Our manufacturing processes adhere to stringent quality management systems. The transformers are designed and tested in accordance with widely recognized international standards such as IEC 60076 and ANSI C57.12.00, ensuring global acceptability. -
Q: How do you ensure product quality and reliability?
A: Our commitment is reflected in our integrated management systems. Every transformer undergoes rigorous factory testing, including ratio, polarity, winding resistance, impedance, and dielectric tests, before shipment to guarantee performance and safety.
