Medium voltage Oil-immersed Power Transformer Feature

• Wide Application Scope for Medium-voltage Distribution：Medium voltage Oil-immersed Power Transformer covers medium voltage levels of 36kV and below, including 15kV, 20kV, 27kV, and can flexibly match diverse power distribution systems such as industrial plants, commercial complexes, and urban-rural distribution networks. Medium voltage Oil-immersed Power Transformer is highly versatile, compatible with the operating parameters of different power grids, and can be customized to meet specific project requirements.
• Stable Operation with Oil-immersed Insulation and Heat Dissipation：Medium voltage Medium voltage Power Transformer adopts high-quality transformer oil as the insulation and heat dissipation medium, which has excellent insulation performance and effectively isolates electrical interference between windings. Combined with the natural cooling/forced air cooling design of corrugated oil tanks or radiators, Medium voltage Oil-immersed Power Transformer has high heat dissipation efficiency, enabling stable operation under long-term full-load conditions with a low failure rate.
• Durable Structure Adaptable to Complex Environments：The oil tank of Medium voltage Oil-immersed Power Transformer is welded with anti-corrosion cold-rolled steel plates, and its surface is treated with sandblasting and painting, providing excellent resistance to moisture, rust and salt spray. With good overall sealing performance, Medium voltage Power Transformer is suitable for complex operating environments such as outdoor areas, coastal regions and dusty places, ensuring a long service life.
• Low Loss and Low Noise for Energy Conservation：Medium voltage Oil-immersed Power Transformer uses high-permeability and low-loss silicon steel sheets for the iron core and high-quality copper materials for precise winding of coils, which greatly reduce no-load loss and load loss, cutting down on electric energy waste. Meanwhile, the optimized structural design of the iron core and windings of Power Transformer effectively reduces operating noise, complying with energy conservation and environmental protection standards.
• Comprehensive Protection and High Safety Factor：Medium voltage Oil-immersed Power Transformer comes standard with protection components such as gas relays, pressure relief valves and thermometers, which can monitor the oil temperature and internal faults in real time to achieve fault early warning and automatic protection. It supports the configuration of on-load tap changers, which can adjust the output voltage in real time according to grid voltage fluctuations to ensure power supply quality.
• Easy Installation and Maintenance with After-sales Guarantee：Oil-immersed Power Transformer has a compact overall structure, and its volume and weight meet the requirements of conventional transportation and hoisting, eliminating the need for complex on-site installation procedures. Daily operation and maintenance only require regular oil quality testing and surface cleaning, with minimal maintenance workload. Professional manufacturers provide multilingual 24-hour hotline and online service platform for Oil-immersed Power Transformer, and certified engineers can offer on-site inspections, predictive maintenance and fault repair services, ensuring long-term stable operation.
