China Suppliers Factory Outdoor Oil Immersed Power Transformer 110kV 10000kVA for Reliable Power Substation Solutions
Low-noise operation is achieved through structural optimization and process improvement. The core is made using a high-precision stacking process, combined with an elastic clamping structure, which reduces core vibration and magnetic expansion noise. The winding is tightly wound and the size is stabilized through constant pressure drying treatment, thereby reducing electromagnetic vibration noise. A low-noise cooling fan (air-cooled type) is selected. The fan starts and stops automatically based on oil temperature and load, further reducing operating noise.
Based on the electromagnetic optimization design concept, the structure is streamlined to the greatest extent while ensuring performance. The layout of the engine body and the dimensions of components are optimized, resulting in a 15%–20% reduction in the equipment's volume compared to traditional products, and a corresponding weight reduction, achieving a lightweight design. An integrated structure design is adopted to reduce redundant components and improve space utilization. This not only lowers transportation difficulty and costs but also saves installation area, especially suitable for installation scenarios with limited space such as urban cores, tunnels, and subways.
Completely use high-quality insulating materials. The insulating components are made of high-strength insulating materials such as high-quality laminated wood and epoxy glass tape, which will not crack or deform even under short-circuit electric force, and can maintain stability.
Deeply integrated into the intelligent power grid construction system, it has a complete intelligent monitoring and control interface, enabling real-time collection and remote transmission of key operating parameters such as oil temperature, oil level, voltage, and current. Equipped with intelligent protection devices, including pressure release valves, temperature controllers, and oil level alarms, when equipment experiences overheating, overpressure, or abnormal oil levels, it can promptly issue alerts and trigger protection actions to prevent the expansion of faults. It supports coordinated operation with new energy power generation systems and energy storage equipment, possesses flexible power regulation and voltage adaptation capabilities, and helps with the grid connection and absorption of distributed energy.
