Advantages of 110 kV power transformer
I. Excellent insulation performance to ensure safe operation under high voltage.
High-quality insulating materials are used. High-strength epoxy castings and high-voltage insulating oil (for oil-cooled transformers) ensure reliable insulation.
Strict manufacturing processes, including vacuum drying and vacuum impregnation, thoroughly remove moisture and impurities from the insulating materials, preventing moisture absorption and aging. The insulation's strength allows it to consistently withstand a rated voltage of 110 kV and resist transient overvoltages, such as switching surges and lightning surges, with a lightning impulse withstand voltage of 350 kV or higher.
The insulation design is optimized through precise control of the insulation thickness between layers and winding turns, as well as segmented insulation winding technology, effectively eliminating hidden problems such as insulation aging, breakdown, and leakage. The transformer ensures stable operation under prolonged high-voltage conditions and continuous operation, 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 loss, a highly efficient energy-saving design is used in the main components. The core is made of oriented silicon steel with high magnetic permeability and low losses, 0.27–0.30 mm thick. A stepped layering technique is used to reduce magnetic resistance and no-load losses.
The windings use high-purity, tin-plated, oxygen-free copper conductors to reduce contact resistance. The winding layout and manufacturing process have been optimized to reduce conductor length and load losses. VII. Customized solutions to meet a variety of grid requirements.
The transformer has extensive customization options to suit customer requirements, network parameters and application scenarios.
