What is a 220 kV transformer?

A 220 kV transformer is a high-voltage equipment designed to convert electricity in power and industrial networks. It reduces high voltage from 220 kV to lower values such as 6 kV, 10 kV or 35 kV, which is necessary for safe and efficient distribution of power at lower levels. 220 kV transformers are widely used in large power grids, substations, and for power supply of industrial facilities, ensuring stable and safe power supply.

The main function of a 220 kV transformer is to maintain the reliability and efficiency of power supply over long distances. These devices are able to operate in various climatic conditions and ensure minimum energy losses. Equipped with adjustable voltage regulators (AVRs), 220 kV transformers can adapt the output voltage in response to load changes, making them ideal for stable operation under varying power consumption.

Types of transformers 220 kV

220 kV transformers are used to convert high voltage to lower voltage, which is necessary for efficient distribution of electricity. There are different types of 220 kV transformers, each with its own features and applications:

220 kV power transformers
Used for power transmission in large power grids. The capacity ranges from 10,000 kVA to 500 MVA. They convert voltage from 220 kV to lower levels, ensuring a stable power supply.
Transformers with adjustable voltage tap changer (VTC)
These transformers automatically regulate the voltage depending on the load, ensuring stable network operation as power consumption changes.
220 kV oil transformers
Transformer oil is used for insulation and cooling. These devices ensure long-term reliability and minimal energy losses.

220 kV transformer - Typical parameters

The 220 kV transformer is the main element for transmission and distribution of electricity in high-voltage networks. Typically, its rated capacity varies from 10,000 kVA to 500 MVA, depending on the power requirements of the network. The rated voltage on the high-voltage input (HV) side is 220 kV and on the low-voltage output (LV) side it ranges from 6 to 35 kV, depending on the specific needs. These transformers can be equipped with adjustable voltage tap changers (AVTs) to adapt to changing loads and ensure system stability.

Efficiency, reliability and durability: Design features of the 220 kV transformer

Magnet core design

Using high quality cold rolled electrical steel with low hysteresis losses and high saturated magnetic induction to ensure efficient transformer operation with minimal energy loss.
Assembly of steel plates is carried out using technology "Step-lap."This provides precise beveling, reducing magnetic flux losses, noise and improving overall transformer efficiency and stability.
Advanced semi-automatic winding is applied to the magnetic circuit assembly, which reduces mechanical stress and ensures low noise during operation, thereby extending the service life of the device.

Winding design and manufacturing techniques

Precision manufacturing technology windingsThe transformer is designed to ensure stability of winding dimensions throughout its service life, as well as improved mechanical strength and reliability of the transformer.
Application rearranged to optimize the winding structure, increase the electromotive impedance under short-circuit conditions, significantly reduce additional losses and improve device safety.
Without winding pre-pressurization - uncompressed design ensures that the transformer will operate reliably over its entire service life without the need for major overhauls.
Use of insulation materials with high withstand stress in the windings to increase their resistance to electric fields and guarantee stable operation of the transformer even under difficult operating conditions.

This design combines advanced technology and materials to provide high energy efficiency, improved safety and long service life, making this transformer the ideal solution for high-performance power systems.
