As a specialized manufacturer with over a decade of experience in electrical power equipment, Jinhua Dika Electrical Equipment Co., Ltd. is proud to present our high-performance Low-loss 1000kVA 11kV Transformer. Engineered for reliability and operational economy, this transformer is designed to meet the rigorous demands of modern power distribution networks and industrial applications. Our commitment to quality, evidenced by our comprehensive ISO management systems, is embedded in every unit we produce, ensuring you receive a product built for longevity and superior performance.
This transformer is a cornerstone for efficient energy transmission, featuring several key design advantages:
- Superior Efficiency: The "Low-loss" design is achieved through advanced core steel and precision-wound 100% copper windings, significantly reducing no-load and load losses compared to conventional models. This translates directly into lower electricity costs and a reduced carbon footprint over the transformer's lifespan.
- Enhanced Reliability & Thermal Management: The use of high-quality mineral oil provides excellent insulating and cooling properties. It effectively dissipates heat generated during operation, maintaining optimal winding temperatures and extending the service life of the insulation materials.
- Robust Construction: The full copper windings offer higher conductivity and better resistance to thermal and mechanical stress than alternative materials, leading to improved short-circuit withstand capability and overall durability in fluctuating load conditions.

Frequently Asked Questions (FAQ)
Q1: What exactly does "Low-loss" mean for this transformer?
A1: "Low-loss" refers to the transformer's design which minimizes energy wasted as heat during operation. This is achieved through high-quality core materials (like grain-oriented silicon steel) and the use of pure copper windings, resulting in lower no-load (core) losses and load (copper) losses. This efficiency directly reduces your electricity consumption costs.
Q2: Why are 100% copper coils considered an advantage over aluminum?
A2: Copper has higher electrical conductivity than aluminum, which allows for smaller, more compact windings that can handle higher currents efficiently. Copper windings also have superior mechanical strength, better resistance to corrosion and thermal cycling, and generally contribute to a longer operational lifespan and higher short-circuit withstand capability.
Q3: Is mineral oil safe and environmentally friendly?
A3: The mineral oil used in our transformers is a high-grade, non-PCB type. It is biodegradable under certain conditions and is a standard, reliable insulating/cooling fluid used globally. All units are designed with sealed tanks and proper safety features to contain the oil. Proper disposal procedures are recommended at end-of-life.
Q4: Can this transformer be customized for voltages other than 11kV/400V?
A4: Yes. As a manufacturer, we offer significant customization. Common variations include primary voltages of 10kV, 13.8kV, or 33kV, and secondary voltages like 415V, 480V, or 600V. Please provide your exact requirements during inquiry.
Q5: What are the standard certifications for this product?
A5> Our production is governed under ISO 9001 (Quality Management) and ISO 14000 (Environmental Management) systems. The transformers can be designed and tested according to international standards such as IEC 60076. Specific national certifications (e.g., ANSI/IEEE for North America) can be addressed as a customizable option based on your market needs.
Q6: What is the typical delivery lead time for an order?
A6> Lead time depends on the order quantity and the level of customization required. For standard-specification units, typical production lead times range from 4-8 weeks ex-works. We provide a firm schedule upon order confirmation.
Q7: Do you provide installation support or technical documentation?
A7> We supply comprehensive documentation including detailed drawings, test reports (routine tests), installation, operation, and maintenance manuals. While on-site installation is typically handled by the client or local contractors, we offer remote technical guidance.
Q8: What after-sales service and warranty do you offer?
A8> We provide a standard warranty period for our transformers, covering manufacturing defects. Our technical support team is available to assist with operational queries. Spare parts for key components are available for long-term support.
