110kv_power_transformer

Our company TSTY produces 110kV oil energy-saving transformers. This series features low loss, low noise, low temperature rise, high reliability, no need for suspension cores and zero leakage. All performance indicators reach the advanced level of similar domestic products. They can significantly reduce network losses and operating costs, providing significant economic benefits. They are suitable for power plants, substations, wind and photovoltaic power plants operating on renewable energy sources, large factories, mines and petrochemical plants.

Characteristics and specifications

110kV oil energy-saving transformers are available with both on-load and off-load tap-change. They are suitable for three-phase power systems with a frequency of 50Hz and a voltage of 110kV and below. Our company adopts advanced domestic and foreign technologies, applies new materials and optimizes the design to improve product performance. These transformers greatly improve electrical and mechanical strength as well as heat dissipation.
