On May 15th, China's first independently controllable domestically produced 110 kV synthetic ester insulating oil transformer successfully passed all type tests, marking significant progress in the field of high-end environmentally friendly electrical materials and equipment technology in China,

On July 11, the PetroChina Open Day activity with the theme of "new technology, new process, new products - tracing high-quality oil products, helping green and low-carbon development" was successfully held in Karamay.This event invited media reporters, customer representatives and partners to

As extreme weather events and natural disasters increase globally, many green initiatives are being implemented in an effort to reduce harm to the earth.Green initiatives have been launched this year in an effort to reduce harm to the environment, as well as increase demand for clean and renewable

The connection of the primary and secondary winding of a three-phase transformer can be designed in different ways according to the desired application and available terminals.Mostly, transformer winding is placed on one core that provides an economic connection between the iron core and copper

The global transformer oil market size is estimated to grow by USD 1.12 billion from 2024-2028, The market is projected to grow at a CAGR of 8.09% during this period. The expansion of transmission and distribution (T&D) networks is driving market growth, with a trend towards eco-efficient

Transformer oil, called insulating oil, plays an important role in cooling and dissipating heat generated during operation. Therefore, selecting the right transformer oil is an essential step to ensure the transformer's performance and longevity. The best choice of transformer oil can impact the

Transformers play a pivotal role in power distribution systems, serving as vital components that step up or step down voltages for efficient transmission. Despite their reliability, transformers are susceptible to various faults that can disrupt their functionality. Understanding these potential

1. Oil injection of the main transformerOil injection of the main transformer refers to the transformer oil into the main transformer, so that the interior reaches a certain oil level and oil pressure. Transformer oil not only has the functions of cooling, insulation and anti-corrosion, but also

Transformer is a device that transforms AC voltage, current and impedance. When there is AC current in the primary coil, the iron core will produce AC magnetic flux (or magnetic core), so that the voltage (or current) is induced in the secondary coil. The transformer is composed of an iron core (or

Because the quality of the transformer oil will directly affect the subsequent operation of the transformer, and will also have a certain impact on the maintenance; so the transformer oil test is an important link in the operation and maintenance of power equipment, and is one of the effective
