Products Description
The 110kV power transformer is a large-capacity, high-reliability core equipment for high-voltage power transmission and transformation. It mainly reduces the 110kV high-voltage level to 35kV/10kV/6.3kV medium and low voltage, which is used for power grid transmission, regional power supply and industrial power distribution.The product adopts high-quality silicon steel sheet and all-copper winding design, and has the characteristics of low loss, low noise, strong short-circuit resistance, and high insulation life. It can operate stably for a long time in harsh environments such as outdoor, high altitude, high cold, high humidity, and heavy pollution. It is widely used in national grid construction, wind power photovoltaic power plants, petrochemical industry, metallurgy, mining and large-scale industrial power supply systems.

Products Advantages
Optimize the iron core and winding structure, no-load and load losses are better than national standards, and long-term operation greatly reduces electricity costs.
The winding reinforcement structure can withstand power grid shocks and short-circuit failures, and reduce the risk of equipment damage.
Equipped with pressure release valve, gas relay, oil temperature/winding temperature control device, it is suitable for outdoor unattended substations.
High-quality insulating oil + fully sealed structure, anti-aging, anti-leakage, and longer maintenance cycle.
It can be used in areas with high altitude, low temperature, high humidity, heavy salt spray, and heavy pollution, with stable performance and no degradation.
Industry application scenarios
