Product Overview
The 100kVA Oil-Immersed Transformer represents an ideal solution for small to medium-scale power distribution applications, offering exceptional reliability and efficiency in diverse operational environments. This transformer is engineered with precision to meet the demanding requirements of rural electrification projects, small industrial plants, commercial buildings, and agricultural facilities. With a compact design that maximizes space efficiency without compromising performance, the 100kVA model delivers consistent power distribution with minimal energy losses.
Designed with advanced ONAN (Oil Natural Air Natural) cooling technology, this transformer maintains optimal operating temperatures even during peak load conditions. The natural convection cooling system eliminates the need for complex mechanical components, reducing maintenance requirements and enhancing long-term reliability. The transformer's 98.5% efficiency rating ensures that energy losses are minimized, translating to lower operational costs and reduced environmental impact.
The 100kVA transformer features a robust construction with premium-grade insulation materials that withstand temperature fluctuations and environmental stresses. Its sealed tank design prevents moisture ingress and oxidation of the cooling oil, extending the service life significantly. The transformer is manufactured to comply with international standards including IEC 60076, ensuring compatibility with global power distribution networks.
Key technical specifications include a primary voltage rating of 10kV or 35kV with a secondary voltage output of 0.4kV, making it suitable for stepping down high-voltage transmission lines to usable distribution voltages. The transformer weighs approximately 2,800 kg and occupies minimal floor space with dimensions of 1.8m × 1.2m × 1.5m. The 850-liter oil capacity provides efficient heat dissipation while maintaining compact dimensions.
This model is particularly suitable for rural electrification projects where reliable power supply is critical for agricultural operations and community development. The low noise level of 68dB ensures minimal environmental disturbance, making it ideal for installations near residential areas. The transformer's robust design enables reliable operation in harsh climatic conditions, from tropical regions with high humidity to arid environments with extreme temperature variations.
For small industrial plants, the 100kVA transformer offers the perfect balance between capacity and cost-effectiveness. It can handle the power demands of light manufacturing operations, food processing facilities, and textile mills. The easy installation process reduces project timelines and minimizes commissioning costs. The transformer's compact footprint allows for flexible placement in space-constrained industrial environments.
Commercial buildings benefit from the transformer's reliable performance and low maintenance requirements. Shopping centers, office buildings, and hospitality establishments can depend on consistent power supply for HVAC systems, lighting, and equipment operation. The transformer's efficiency helps reduce operational electricity costs, contributing to improved building management economics.
For agricultural applications, the 100kVA transformer supports irrigation systems, grain processing equipment, and farm mechanization. The reliable power supply enables farmers to maximize productivity and reduce operational downtime. The transformer's durability ensures years of trouble-free operation in challenging agricultural environments.
Precautions and maintenance considerations include regular oil analysis to detect any degradation or contamination. Annual visual inspections should verify the integrity of the tank and cooling system. The transformer should be protected from moisture ingress through proper ventilation and drainage systems. Temperature monitoring ensures the cooling system operates effectively, and any abnormal temperature rises should be investigated immediately.
The 100kVA Oil-Immersed Transformer represents an investment in reliable, efficient power distribution infrastructure. With its proven track record in diverse applications worldwide, this transformer delivers consistent performance and long service life, making it an excellent choice for small to medium-scale power distribution projects.
