As a specialized manufacturer of electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. is proud to present our 1000kVA 11kV Oil-Immersed Distribution Transformer with 100% Copper Windings. Designed for reliability and efficiency in demanding power distribution networks, this transformer is engineered to deliver stable voltage transformation with minimal energy loss. Our extensive experience, backed by a robust export portfolio serving markets from North America to Southeast Asia, ensures that every unit meets stringent performance and safety standards. This product exemplifies our commitment to providing durable and cost-effective solutions for utility companies, industrial plants, and commercial facilities worldwide.
This transformer is a cornerstone for medium-voltage distribution, converting 11kV primary voltage to standard low-voltage levels for end-user consumption. Its construction prioritizes longevity and operational stability, making it a smart investment for long-term infrastructure projects.
Core Features & Technical Advantages:
- 100% Copper Windings: The use of high-conductivity copper ensures superior electrical performance, lower operating temperatures, and enhanced resistance to thermal cycling compared to aluminum alternatives. This translates to higher efficiency, reduced energy losses over the transformer's lifespan, and greater overload capacity.
- Optimized Oil-Immersed Design: The core and windings are fully immersed in high-grade insulating oil, which provides excellent cooling and insulation. This design effectively dissipates heat, prevents partial discharges, and protects internal components from moisture and contaminants, ensuring reliable operation in various environmental conditions.
- Robust Mechanical Construction: The tank is fabricated from durable steel, with reinforced structures to withstand mechanical stresses during transportation and operation. All external fittings, including bushings, conservator, and radiators, are selected for their reliability and ease of maintenance.
- Customizable Configurations: We understand that project requirements vary. Key parameters such as the vector group (e.g., Dyn11, Yyn0), tap-changer options (off-circuit or on-load), and mounting style (pole or pad) can be tailored to meet specific grid and installation needs.

Frequently Asked Questions (FAQ):
-
Q: What are the primary advantages of copper windings over aluminum in a transformer of this size?
A: Copper offers higher electrical conductivity, which results in lower resistive losses (I²R losses) under load. This leads to better energy efficiency, improved thermal performance (runs cooler), and greater mechanical strength, which is particularly beneficial for withstanding short-circuit forces. Over the transformer's lifetime, the energy savings often offset the higher initial material cost. -
Q: Is this transformer suitable for both 50Hz and 60Hz power systems?
A: Yes, the design can be optimized for either 50Hz or 60Hz operation. The specific core design and loss calculations will be adjusted accordingly based on your stated frequency requirement during the ordering process. -
Q: What kind of maintenance does an oil-immersed transformer require?
A: Routine maintenance includes periodic checks of oil level and quality (through DGA - Dissolved Gas Analysis), inspection of bushings and gaskets for leaks, tightening of electrical connections, and cleaning of radiators. The robust design minimizes maintenance needs, but a scheduled inspection program is recommended for optimal longevity. -
Q: Can you provide transformers with on-load tap changers (OLTC)?
A: Yes, on-load tap changers are an available option. They allow for voltage regulation while the transformer is energized, which is crucial for maintaining stable voltage levels in grids with fluctuating loads. This feature can be specified based on your project's requirements. -
Q: What is the typical delivery lead time for a custom-configured 1000kVA unit?
A: Lead times vary based on order volume and customization complexity. Generally, for standard configurations, production can be completed within 6-8 weeks after order confirmation. We provide accurate timelines during the quotation phase. -
Q: Do you offer any warranty on your distribution transformers?
A: Yes, we provide a standard warranty covering manufacturing defects. The specific terms and duration are detailed in our commercial contract and are aligned with industry practices. -
Q: How do you ensure the transformer withstands transportation stresses?
A: We employ robust packaging, including sturdy wooden crates, internal bracing to immobilize the core-coil assembly, and shock-absorbing materials. The transformer is rigorously tested before dispatch, including a final impulse and induced overvoltage test, to guarantee it arrives in perfect working condition. -
Q: Are eco-friendly insulating fluids an option for this transformer?
A> Absolutely. In addition to traditional mineral oil, we can fill the transformer with biodegradable ester-based fluids upon request. These fluids offer a higher fire point and improved environmental safety profile.
