Advantages of 110 kV Power Transformer
I. Excellent Insulation Performance to Ensure Safe Operation at High Voltage.
High-quality insulation materials are used. High-strength epoxy castings and high-voltage insulating oil (for oil-immersed transformers) provide reliable insulation.
During the production process, strict technological procedures are applied, including vacuum drying and vacuum impregnation, to thoroughly remove moisture and impurities from the insulation materials, preventing moisture absorption and aging. The insulation strength allows it to stably withstand the rated voltage of 110 kV and resist transient overvoltages such as switching overvoltages and lightning overvoltages, with a lightning impulse withstand voltage of 350 kV and above.
The insulation design is optimized through precise control of insulation thickness between layers and turns of the windings, as well as segmented insulation winding technology, effectively eliminating hidden issues such as insulation aging, breakdown, and leakage. The transformer ensures stable operation under prolonged high voltage and continuous use, significantly reducing the risk of shutdowns and maintenance caused by insulation failures.
II. Low-loss and energy-saving design to reduce long-term operating costs.
To minimize power losses in key components, a high-efficiency energy-saving design is adopted. The core uses oriented silicon steel with high magnetic permeability and low losses, with a thickness of 0.27–0.30 mm. Stepped lamination is employed to reduce magnetic resistance and no-load losses.
The windings use conductors made of high-purity oxygen-free copper with a tinned coating to reduce contact resistance. The arrangement of the windings and the manufacturing process are optimized to reduce conductor length and load losses. VII. Custom solutions to meet diverse power grid requirements
The transformer offers extensive customization options according to customer requirements, network parameters, and application scenarios.
Power rating: 6300 kVA - 125000 kVA
Connection groups: YNd11, Yyn0, Dyn11, etc.
Cooling modes: ONAN, OFAF, ODAF for oil-immersed systems; dry type for indoor, high-altitude, and fire-prone areas.
Intelligent monitoring modules can be integrated into the system, including temperature, oil level, partial discharge, and vibration sensors, enabling real-time data transmission, remote monitoring, early warning, and fault diagnosis for smart grids and smart substations.
