11kV/433V, 500 KVA Transformer
Usha Electric proudly presents the redesigned 11kV/433V, 500 KVA Transformer, a high-efficiency solution engineered for reliable power distribution in industrial, commercial, and utility applications. Built with state-of-the-art technology and robust materials, this transformer ensures optimal voltage regulation, minimal energy losses, and long-term durability, making it an ideal choice for industries such as steel, cement, power utilities, and large-scale infrastructure projects.
Key Features of the Redesigned 11kV/433V, 500 KVA Transformer
1. High-Efficiency Voltage Transformation
The 500 KVA Transformer steps down voltage from 11kV to 433V, delivering stable power for industrial and commercial loads. Utilizing high-grade copper or aluminium windings and cold-rolled grain-oriented (CRGO) steel cores, it achieves low core losses and high efficiency, compliant with IEC 60076 and IS 2026 standards.
2. Robust and Safe Construction
Designed with a fully enclosed, oil-immersed tank, the transformer features ONAN (Oil Natural Air Natural) coolingfor effective heat dissipation. Its IP55-rated enclosure ensures protection against dust and moisture, while safety features like Buchholz Relay, Oil Temperature Indicator (OTI), and Winding Temperature Indicator (WTI) provide real-time monitoring and fault protection.
3. Versatile and Customizable
With a 500 KVA rating, the transformer supports three-phase, 50 Hz systems and is available in Dyn11 vector groupconfiguration for efficient power distribution. It includes an On-Load Tap Changer (OLTC) or Off-Circuit Tap Changer (OCTC) for precise voltage regulation, making it adaptable to varying load conditions in industrial and utility settings.
4. Eco-Conscious and Low Maintenance
The transformer uses Type II mineral oil with less than 2 ppm PCB content, ensuring environmental compliance. Its robust design minimizes maintenance needs, with only periodic oil testing and thermographic surveys recommended. The use of recyclable materials aligns with Usha Electric’s commitment to sustainability.
5. Compact and Durable Design
The transformer’s compact footprint optimizes space in substations or industrial setups. Its corrosion-resistant, epoxy-coated tank ensures durability in harsh environments, while the sealed design prevents oil leakage and enhances operational reliability over an extended lifespan.
Applications
The 11kV/433V, 500 KVA Transformer is engineered for a wide range of high-performance applications, including:
Steel Plants: Powers heavy machinery and production lines with stable voltage.
Cement Industries: Supports high-demand equipment under variable loads.
Power Utilities: Steps down voltage for local distribution networks.
Commercial Complexes: Ensures reliable power for offices, malls, and hospitals.
