Product Description

Product Description:

Oil-immersed power transformers are highly efficient electrical machines that play a crucial role in the transmission of electrical power. They are specifically designed to operate between high-voltage and low-voltage networks, typically rated around 35kV.

The main purpose of these transformers is to convert voltage levels to facilitate the smooth distribution of electrical energy across the power grid. By stepping voltage up or down, they help in minimizing power losses during transmission and ensure that electricity reaches consumers safely and reliably.

Additionally, oil-immersed power transformers provide automatic voltage regulation, which helps maintain the stability of the electrical grid. This function is vital for the consistent operation of electrical systems and for protecting equipment from voltage fluctuations.

Overall, these transformers are essential components for effective power distribution, contributing significantly to the efficiency and reliability of electrical supply networks.


Features:

The product features efficient heat dissipation by utilizing an oil-immersed cooling design. This approach results in low load losses, particularly within the 600-630V range, making it well-suited for high-load industrial settings.

It offers strong insulation properties through the use of insulating oil, which significantly improves the insulation between the windings. This enhancement helps to prevent short circuits and ensures reliable operation.

Additionally, the product has excellent overload capacity, capable of handling short-term overload conditions. Its simple structure contributes to ease of maintenance and reduces overall upkeep costs.


Applications:

Power System: Essential Equipment for High Voltage Transmission to Low Voltage Distribution

The power system serves as a critical network that facilitates the efficient transfer of electrical energy from high voltage transmission lines down to low voltage distribution systems. This transformation is vital to ensure safe and reliable electricity delivery to various end users.

In industrial and mining sectors, power systems play a pivotal role by providing the necessary electrical supply to operate large-scale machinery and extensive production lines. These enterprises depend on stable and continuous power for their daily operations and industrial processes.

Additionally, transportation infrastructures benefit significantly from power systems. Rail transit systems, including railways and subways, rely heavily on these power solutions to support their electrical needs, ensuring smooth and efficient operation of trains and related equipment.
