Product Description:

Medium and high voltage oil-immersed transformers play a crucial role in power systems by facilitating voltage transformation. These transformers are essential components that help in adapting voltage levels to meet the requirements of different parts of the electrical grid.

One of the key features of these transformers is their use of insulating oil. This oil serves a dual purpose: it provides effective cooling to prevent overheating and acts as an insulator to enhance electrical stability. The presence of this oil ensures the transformer can operate reliably, even when subjected to heavy electrical loads.

Thanks to their robust cooling and insulation properties, oil-immersed transformers maintain stable performance in demanding conditions. This makes them a preferred choice for medium and high voltage applications within power distribution and transmission networks.



Features:

Advantages of Medium and High Voltage Oil-Immersed Transformers

Medium and high voltage oil-immersed transformers are renowned for their high reliability and stability. These transformers benefit from excellent insulation properties and robust resistance to short circuits, ensuring consistent performance even under demanding electrical conditions.

Another significant advantage is their efficient cooling capability. The use of oil, which possesses superior heat dissipation qualities, helps to effectively manage the transformer's temperature. This efficient cooling mechanism reduces energy loss and enhances overall operational efficiency.

The insulating performance of these transformers is also noteworthy. The dielectric strength of the oil provides strong insulation, which plays a crucial role in preventing arc breakdowns and electrical faults. This feature significantly contributes to the longevity and safety of the equipment.

From an economic perspective, oil-immersed transformers offer cost-effectiveness. Although there are environmental considerations regarding mineral oil usage, its widespread application continues due to affordability and proven reliability in transformer technology.

Additionally, these transformers exhibit a compact design, often incorporating attributes such as axial symmetry and dual high-voltage output terminals. Such design elements improve portability and ease of integration into diverse electrical systems.

Given these advantages, medium and high voltage oil-immersed transformers are well-suited for various applications including power transmission networks, substations, and equipment testing environments.


Technical Parameters:

The transformer has a capacity of up to 120 MVA, making it suitable for a variety of high-demand electrical applications. It operates with voltage levels ranging from 33 kV to 110 kV on the primary side and from 10 kV to 69 kV on the secondary side.

The pressure regulating gear and short circuit impedance are designed and customized according to specific project requirements, ensuring optimal performance tailored to the user's needs.

This transformer utilizes an oil-immersed, air-cooled (ONAF) cooling method to maintain efficient thermal management. The temperature rise is limited to a top oil temperature of 95°C or below, even when the surrounding environment temperature reaches 40°C.

In terms of compliance, the transformer conforms to the GB 1094.1-2013 standard, which governs the operating regulations for oil-immersed transformers. This ensures reliability and safety in its operation.

Typically, this transformer is applied in distribution networks where it steps down voltage from 110 kV substations to 35 kV systems, making it ideal for regional power distribution scenarios.


Applications:

The TNNPI Oil Immersed Power Transformer, model number SZ, is a high-quality Electrical Power Transformer designed and manufactured in Zhengzhou. Certified with CE and ISO standards, this three-phase Electric Power Transformer ensures reliable performance and safety under outdoor service conditions. With a winding combination of H--L and using mineral oil (NON-PCB) as the insulating liquid, it offers excellent insulation and cooling properties, making it suitable for various demanding electrical power applications.

This Electrical Power Transformer is ideal for use in electrical substations, power generation plants, and distribution networks where stable voltage transformation is critical. Its robust design and mineral oil insulation provide enhanced durability and efficiency, ensuring uninterrupted power supply in both urban and rural areas. The SZ model is especially suited for outdoor installations, capable of withstanding harsh weather conditions without compromising performance.
