Product Description

Product Description:

This product demonstrates high-level energy efficiency by adhering to the rigorous German and European energy efficiency standards, such as EN 50464. It achieves no-load and load losses that are 15% to 20% lower than conventional models, which guarantees enhanced energy savings during prolonged periods of operation.

Designed for high reliability, it incorporates premium silicon steel sheets and insulation materials that are resistant to aging. This construction provides robust protection against short circuits and voltage fluctuations, making the product well-suited for complex and demanding power grid environments.

Featuring a compact structure, the design is tailored to fit the spatial limitations commonly found in both urban and rural power distribution systems throughout Germany. In addition, strict noise control measures have been implemented to ensure compliance with European environmental noise standards, resulting in quieter operation.

Safety is prioritized through the use of a fully sealed oil tank combined with flame-retardant transformer oil. These features meet German regulations regarding fire prevention and explosion protection, significantly reducing operational risks and enhancing overall safety.

The product is perfectly adapted to the local power grid specifications, with a high-voltage side primarily operating at 10kV or 20kV. The low-voltage side aligns with German distribution voltage standards, offering 400V for three-phase and 230V for single-phase systems, thereby ensuring strong compatibility within the existing infrastructure.


Technical Parameters:

The capacity range of the equipment spans from 50kVA to 1600kVA, making it suitable for a wide variety of power requirements.

It operates under high-voltage conditions in accordance with national standards, supporting voltages from 10kV up to 35kV.

For low-voltage applications, it complies with national standards as well, providing voltages of 380V and 220V.

The energy efficiency rating of the product is classified as S13 according to the EN50464 standard, ensuring optimal performance and energy savings.

Regarding cooling, the system uses the ONAN method, which stands for Oil Natural Air Natural, facilitating effective temperature regulation without the need for additional cooling equipment.


Applications:

Residential power distribution involves the management and delivery of low-voltage electricity networks within urban neighborhoods, community areas, and rural regions. These systems ensure that homes and local infrastructures receive a reliable supply of power for daily use.

In the industrial sector, power distribution focuses on supplying electricity to machinery and equipment located in factory workshops as well as warehousing and logistics parks. This facilitates smooth and efficient production operations by providing consistent electrical energy.

Public facilities such as schools, hospitals, shopping centers, and subway stations rely on dedicated power supply systems. These specialized networks are designed to meet the unique energy demands of these institutions, ensuring safety and uninterrupted service.

The rural power grid encompasses projects aimed at upgrading and transforming electrical infrastructure in towns and villages. These initiatives enhance the quality and stability of electricity supply in rural areas, fostering development and improving living standards.
