Product Description

Product Description:

Oil-immersed power transformers are highly efficient electrical apparatuses designed mainly for power transmission and the regulation of voltage levels. They play a crucial role in managing the voltage between high-voltage systems at 35kV and the corresponding low-voltage networks.

These transformers perform essential functions such as converting voltage levels to meet the requirements of different grid segments. Additionally, they facilitate the distribution of electrical power across the network, ensuring that energy is delivered effectively where needed.

Another vital capability of oil-immersed transformers is automatic voltage regulation. This feature helps maintain a steady and reliable operation of the power grid by adjusting voltage fluctuations, thus contributing to the overall stability and efficiency of the electrical system.


Features:

Efficient heat dissipation is achieved by utilizing an oil-immersed cooling design. This approach ensures low load loss, particularly within the voltage range of 600 to 630 volts, making it highly suitable for demanding industrial environments where high loads are common.

The transformer features robust insulation properties, thanks to the use of insulating oil. This oil significantly improves the insulation between the windings, effectively preventing any short circuits and enhancing overall safety and reliability.

Additionally, the device boasts excellent overload capacity. It is capable of withstanding short-term overloads without any adverse effects. Its simple structural design not only contributes to durability but also helps in minimizing maintenance costs over time.


Applications:

Power System: Essential Components for Voltage Transmission

The power system plays a critical role in managing the flow of electricity from high voltage transmission lines down to low voltage distribution networks. This transition is vital for efficiently delivering electrical energy to various end users while maintaining system stability and safety.

In industrial and mining sectors, power systems provide the necessary electricity to operate heavy machinery and extensive production lines. Reliable power supply in these environments ensures the smooth functioning of complex equipment and continuous manufacturing processes.

Transportation infrastructure also depends heavily on power systems. Rail transit systems, including railways and subways, require stable electrical power to support operations, ensuring timely and efficient movement of passengers and goods.
