High-temperature resistant liquid-immersed traction transformers for electrified railroads are suitable for high-speed railroads, heavy-duty railroads and harsh environments such as high temperature, humidity, etc., and can meet the demand for high reliability and high performance of railroad traction power supply. It is widely used in electrified railroads and urban rail transit both at home and abroad, providing stable and reliable power support for trains, and maintaining excellent performance even in extreme environments.
High-temperature resistant performance: Adopting high-temperature resistant insulating materials and liquid cooling technology, it adapts to high-temperature environments and ensures long-term stable operation.
High-efficiency energy conversion: low loss and high efficiency to meet the demand of railroad traction high-power loads.
Environmental protection and safety: using environmentally friendly insulating liquid, fire-resistant and non-toxic, in line with international safety standards.
Adapt to harsh environment: suitable for high humidity, salt spray, vibration and other complex working conditions, widely used in various railroad scenarios.
Flexible customization: modular design, support for customization, easy installation and maintenance, adapt to a variety of line requirements.
Long life and low cost: optimized structure, less operation and maintenance, economic and efficient, to ensure the stability of railroad power supply.
Safe and reliable
As the key equipment of electrified railroad, the traction transformer is of reliable quality, which eliminates the power outage of the whole office caused by equipment failure and guarantees the efficient operation of railroad transportation.
Energy saving and high efficiency
Adopting low-loss design, it significantly reduces operating energy consumption, saves production cost and improves the energy utilization efficiency of railroad system.
Superior overload capability
With low loss and low temperature rise characteristics, it operates stably under overload conditions, improves capacity utilization and further reduces operating costs.
High life and low maintenance
It realizes low maintenance or maintenance-free design, reduces interruption of power supply time and ensures continuous operation, which is in line with the modern equipment management concept of “state control and life management”.
