Product Description

Product Description:

The Oil Immersed Distribution Transformer is a robust and reliable solution designed for efficient electric power distribution. With power ratings ranging from 30 to 1600 KVA, this transformer caters to a wide variety of applications, ensuring optimal performance in diverse electrical networks. It is engineered to handle voltage ratings of up to 33kV, making it suitable for medium voltage distribution systems and providing flexibility for different installation requirements.

This product is specifically designed to operate with a primary voltage of 13.8KV, which is a common voltage level in many electrical distribution grids. For instance, the 13.8kv 500kva distribution transformer variant is widely used in commercial and industrial settings where reliable power supply and voltage regulation are critical. Similarly, the 630kva kva distribution transformer model is popular for its balance between capacity and efficiency, making it an ideal choice for medium-scale power distribution needs.

Manufactured in compliance with international standards such as IEC 60076, ANSI, and IEEE, the Oil Immersed Distribution Transformer guarantees safety, durability, and performance. These standards ensure that the transformer meets stringent quality and reliability benchmarks, making it suitable for use in various regions and adhering to global industry norms. The compliance also assures users of the transformer's capability to withstand electrical and mechanical stresses over its operational lifespan.

The design of the Oil Immersed Distribution Transformer includes high-quality insulation oil that immerses the core and windings. This oil acts as both an insulating medium and a coolant, enhancing the transformer's thermal performance and longevity. The oil immersion helps in efficiently dissipating heat generated during operation, thereby preventing overheating and reducing maintenance requirements. This feature is particularly beneficial in ensuring the transformer's stable performance under continuous load conditions.

Electric power distribution transformers like this model play a crucial role in the electrical supply chain by stepping down high voltage electricity from distribution lines to lower voltages suitable for residential, commercial, and industrial use. The Oil Immersed Distribution Transformer is engineered for minimal energy losses, high efficiency, and excellent voltage regulation, helping to maintain a stable and reliable power supply. Its robust construction allows it to operate effectively in various environmental conditions, including outdoor installations.

Moreover, this transformer is designed for ease of installation and maintenance, with features that facilitate quick access to internal components and straightforward connection to existing power infrastructure. The versatility in power ratings, from 30 KVA up to 1600 KVA, accommodates different load requirements, making it a flexible choice for utilities and private enterprises alike.

In summary, the Oil Immersed Distribution Transformer is an essential component in modern electric power distribution systems. Its adherence to international standards, combined with its wide range of power and voltage ratings, including the popular 630kva kva distribution transformer and the 13.8kv 500kva distribution transformer variants, ensures dependable performance and operational efficiency. Whether used in urban, suburban, or rural settings, this transformer delivers reliable voltage transformation, contributing to the stability and efficiency of the power grid.


Technical Parameters:

The rated capacity of these transformers ranges widely, starting from 30kVA and extending up to 2500kVA. For single-phase transformers, the maximum capacity is typically around 833kVA.

Regarding the voltage levels, the high voltage side usually operates at either 10kV or 35kV. Meanwhile, the low voltage side commonly uses a standard voltage of 230/400V.

These transformers are designed to function at frequencies of either 50Hz or 60Hz, accommodating different regional electrical standards.

The no-load loss is dependent on the transformer's capacity. For example, a 500kVA transformer generally experiences a no-load loss of approximately 1.10kW. When under load, the same transformer experiences a load loss close to 7.40kW.

The no-load current typically falls within the range of 0.7% to 2.5% of the rated current, indicating the current drawn when the transformer is energized but not supplying any load.

Lastly, the short circuit impedance of these transformers usually ranges between 4% and 6%.


Applications:

The urban distribution network plays a critical role in electricity delivery by transforming high voltage power into voltage levels that are appropriate for both residential and commercial use. This conversion ensures a stable and reliable power supply for everyday consumption.

In industrial settings, power supply systems provide adjustable voltage tailored for various factory equipment, such as CNC machine tools and injection molding machines. This customization supports smooth and efficient production operations.

For high voltage generator applications, voltage conversion is essential during the power generation process. This step helps to optimize the efficiency of energy transmission, ensuring minimal loss and improved performance throughout the system.
