2000 KVA Oil Filled Transformer for Substation Voltage Conversion
Nov 07, 2025
Leave a message
A 2000kVA oil-immersed transformer is a high-capacity distribution transformer used to step down voltage for industrial, agricultural, and power grid applications. It is a robust and efficient power solution that uses mineral oil for insulation and cooling, features like low losses and high short-circuit withstand strength, and can be found in various configurations, such as hermetically sealed models that minimize maintenance and environmental impact.
Why the 2000 kVA Oil Filled Transformer Excels for Indoor MV/LV Systems
Our hermetically sealed, oil-immersed 2000 kVA transformer is built to address the unique challenges of indoor installation, where space efficiency, cooling reliability, and long-term durability are non-negotiable:
Hermetic Sealing for Maximum Protection: Unlike non-sealed transformers, this unit's airtight design prevents moisture, dust, and contaminants from entering the oil-filled core and windings. This not only extends the transformer's lifespan (reducing oil degradation and corrosion) but also eliminates the need for frequent oil sampling or top-ups-cutting maintenance costs for your MV/LV distribution system.
ONAN Natural Cooling for Indoor Compatibility: Engineered with natural (ONAN) cooling (Oil Natural/Air Natural), the 2000 kVA oil filled transformer operates efficiently without relying on external fans or pumps. This makes it ideal for indoor spaces where forced cooling systems might be impractical or pose noise concerns, while still maintaining stable operating temperatures even under full 2000 kVA load.
Tailored for Three-Phase MV/LV Distribution: Every component-from the copper windings to the high-grade insulating oil-is optimized for three-phase power flow, ensuring consistent voltage regulation and low energy losses. Whether powering manufacturing equipment, commercial buildings, or data centers, this transformer delivers the steady, safe power your MV/LV system requires.
Key Benefits for Your Indoor Power Infrastructure
Choosing the right 2000 kVA oil filled transformer isn't just about meeting capacity needs-it's about enhancing your entire distribution system's performance:
Space-Saving Design: Compact dimensions fit seamlessly into indoor electrical rooms or tight infrastructure spaces, without compromising on cooling efficiency.
Compliance with Global Standards: Manufactured to adhere to IEC, ANSI, and other industry benchmarks, ensuring compatibility with existing MV/LV setups and regulatory compliance.
Low Total Cost of Ownership: Hermetic sealing and ONAN cooling reduce maintenance labor and replacement parts, while low energy losses lower long-term utility costs.
Advantages of 2000 kVA Oil immersed Transformer
Flexible standard adaptation: Supports international standards such as GB, IEC, and UL, with customization available based on customer requirements;
Multi-national authoritative certifications: Certified by ISO, CE, UL, etc., ensuring reliable quality;
High efficiency: Exceeds 99% efficiency, complying with the European Tier 2 energy efficiency regulation (2015/2014/548/EC) for excellent energy savings;
Maintenance-free operation: Features IP65 protection class for dust and moisture resistance, with a design life of over 25 years for hassle-free use;
Environmental friendliness: Optional FR3 vegetable oil, meeting environmental protection and sustainable development needs;
Strong overload capacity: Copper coil design allows short-term overload up to 150% of rated capacity (maximum 2 hours), with only oil temperature monitoring required (≤95℃).
