Electric Power Substation Transformers - 220KV-69KV-138KV

220 kv transformer
Substation - what is it?

Substations transmit voltage low to high or high to low and then distribute it to the generators. Electricity needs to travel great distances; therefore, it is transmitted with a high voltage and low current level to reduce the loss of current.

To protect and distribute the power in the most efficient matter, the substation is equipped with fuses, circuit breakers, and other supporting devices. Substations are typically located in an open environment within a tightly fenced compound.

Functions of the Substation The following functions are the primary functions of the Substation:

Increasing and decreasing the voltage

Switching

Power Cuts

Protection System

Market for US power transformers is expected to be dominated by the United States.

The National Grid has requested approval for a $15 million electrical substation in Bethlehem, New York. Equinor and BP won 2.49GW off-shore wind contracts during an auction in the US.

To reduce load on the existing electrical network in Harmony by building a new substation in 2019, National Grid decided to do so in order to improve reliability.

A combination of renewable energy networks and energy efficiency policies are the key forces driving the growth of the US transformers market.

Increased energy demand in the country and upgrades of outdated transmission and distribution systems are likely to drive the country's transformer market.

Considering the constant increase in energy demand and an increasing number of commercial and industrial activities in the country, the United States is likely to be the largest market for transformers in North America.There have also been significant investments in renewable energy, which require a large number of power and distribution transformers to transfer electricity from the facility to the consumers. In 2022, the United States added 17908 megawatts.

As a result, the United States is expected to dominate the North America transformer market throughout the forecast period.

So we can see that large power substation transformers take the largest market share?

In the power transformer market, the large power transformer is the most common. Its power ranges are normally above 200 megavolt amps (MVA). Few companies produce large power transformers, thus it is difficult for them to compete.

In developed countries, new transformers are being installed to ensure a continuous and efficient supply of electricity. This trend is expected to increase over the forecast period. In the coming years, eco-friendly, large power transformers are expected to see significant growth.

The State Grid Corporation of China (SGCC) contracted ABB to provide converter transformers and high-voltage equipment for the 800 kV UHVDC transmission link in 2019; the project was one of ABB's largest power transmission projects to date.

What role do Chinese power substation transformer manufacturers play?

China's transformers will develop in the direction of environmental protection and miniaturization

In recent years, China has experienced rapid economic development and increasing demand for electricity. At the same time, China has also introduced various policies to speed up the construction of projects such as west-to-east power transmission, north-south mutual supply, and cross-regional networking, which has driven China's power transmission and distribution equipment. rapid development of the industry. Judging from the current market development, in the next few years, my country's transformer manufacturing industry will usher in a period of continuous and stable development.

At the same time, with the continuous deepening of China's "energy saving and consumption reduction" policy, the state encourages the development of energy-saving, low-noise and intelligent distribution transformer products. Some high-energy-consumption distribution transformers running on the grid are no longer in line with the development trend of the industry, facing the need for technological upgrading and replacement, and will be gradually replaced by energy-saving, material-saving, environmental protection, and low-noise transformers in the future.

Foreign markets become the blue ocean market for Chinese transformer companies

At present, the internal price competition in China's transformer industry has become fierce. In the conventional transformer market, some small and medium-sized transformer manufacturers even sell their products at cost or loss prices to seize market share. A large number of small and medium-sized transformer manufacturers in China closed down one after another due to low gross profit margins, which led to difficulties in capital flow.

Based on this market situation, some Chinese transformer manufacturers have begun to shift their market focus to overseas markets. According to the characteristics of different overseas markets, Chinese transformer manufacturers have adopted different strategies for going overseas: relying on the Chinese government's "One Belt, One Road" strategy to cooperate with governments in Southeast Asia, Africa and other countries. Such orders do not have high requirements for transformer process standards, so their profits are relatively limited; taking advantage of price, process and other advantages, they strive for orders for power grid renovation projects in developed countries such as the United Kingdom, the United States, and Europe. Most of the power grids in developed countries in Europe and the United States were formed in the 1950s and have been unable to adapt to the current demand for electricity. Therefore, a large number of power grid-supporting facilities have been purchased. This type of order has a high level of profit, but the bidding intensity is higher than other types of orders.

In addition, as the main component of the power grid, power transformers are an industry with heavy materials and light industries, and material costs account for more than 60% of the cost of the entire product. Therefore, the anti-risk capabilities of low-end and medium-end transformer manufacturers are generally weak. To solve the problem of low-end overcapacity, it is still necessary to strengthen the research and development of high-end products and technological breakthroughs.

Although China's transformer industry products are still concentrated in the medium and low voltage field, there are still many manufacturers with the production capacity of transformers above 500 kV. Compared with the internationally famous transformer manufacturing enterprises, the domestic enterprises have completely caught up in the technical level. At present, TBEA Co., Ltd. (referred to as "TBEA"), China Xidian Group, Baoding Tianwei Baobian Electric Co., Ltd. (referred to as "Tianwei Baobian") and other enterprises have equipped with 1000 kV and above UHV Transformer production capacity.

UHV transformers represent the highest level of power transformer technology in the world. At present, my country's UHV transformer technology has reached the world level. The UHV transformers and reactors developed by TBEA, Tianwei Baobian, and China Xidian Group have been successfully operated in the test and demonstration projects; the ±800kV DC transmission converter transformers have also been successfully developed and put into operation; a batch of UHV new products such as 1000 kV, 1500 MVA UHV AC transformer (single-phase), 1000 kV, 400,000 KVA generator transformer, ±1100 kV UHV DC transmission converter transformer, UHV New products such as variable reactors have also been successfully developed.
