Oil Immersed Power Transformer Rated Power 5000kva 10000kva 20MVA In Ideal Solution For Power Distribution

Product Description:

Medium and high voltage transformers that are immersed in oil play a crucial role in power systems for the purpose of voltage conversion. These transformers are essential components in electrical networks, facilitating the safe and efficient transformation of voltage levels.

The insulating oil used within these transformers serves two primary functions: cooling and electrical insulation. By dissipating heat generated during operation, the oil helps maintain an optimal temperature, preventing overheating and extending the lifespan of the equipment.

Additionally, the insulating properties of the oil ensure reliable performance even under heavy load conditions. This enhances the stability and safety of the power system, making oil-immersed transformers a preferred choice in medium and high voltage applications.

Features:

Medium and high voltage oil-immersed transformers are known for their exceptional reliability and stability. They offer excellent insulation properties and demonstrate strong resistance to short circuits, ensuring consistent and safe operation in various electrical applications.

One of the key benefits of these transformers is their efficient cooling system. The oil used in these transformers has superior heat dissipation capabilities, which helps to minimize energy loss and maintain optimal operating temperatures even under heavy loads.

Additionally, the oil provides robust insulation due to its high dielectric strength. This characteristic effectively prevents arc breakdowns, enhancing the overall safety and longevity of the transformer.

From a cost perspective, oil-immersed transformers remain economical. Despite some environmental concerns associated with mineral oil, it continues to be widely utilized because of its affordability and proven performance.

Moreover, these transformers feature a compact design, often incorporating axial symmetry and dual high-voltage output options. Such design elements contribute to their portability and ease of installation in various settings.

Owing to these advantages, medium and high voltage oil-immersed transformers are ideally suited for power transmission systems, electrical substations, and equipment testing environments.

Technical Parameters:

This transformer has a capacity of up to 120 MVA, making it suitable for various medium to large scale power distribution needs.

The voltage levels are designed with flexibility in mind, featuring a primary side range from 33 kV to 110 kV, and a secondary side ranging from 10 kV to 69 kV.

The pressure regulating gear and short circuit impedance can be customized to meet specific project requirements, ensuring optimal performance and safety.

For cooling, an oil immersed air-cooled (ONAF) method is employed, which effectively dissipates heat to maintain operational stability.

The temperature rise limit is set with a maximum top oil temperature of 95 ℃ under an ambient temperature of 40 ℃, ensuring reliable and safe operation within specified thermal conditions.

The transformer adheres to the applicable standards outlined in GB 1094.1-2013, which governs the operation of oil immersed transformers.

It is typically used in distribution systems where 110 kV substations are stepped down to 35 kV, offering an efficient solution for voltage transformation in such scenarios.
