Why Is There A High Demand For Oil Immersed Transformers in Pakistan in 2023

Why is there a high demand for oil immersed transformers in Pakistan in 2023

In recent years, the development of electricity in Pakistan has shown the following trends:

Electricity consumption growth: From 2018 to 2023, Pakistan's electricity consumption was 104000 GWh. Over the past five years, the average growth rate of electricity consumption has been 5.7 percentage points. In terms of electricity consumption, residential electricity accounts for 51%, industrial electricity accounts for 24%, and commercial electricity accounts for 8%. It is expected that in the future, with the increase of Pakistan's GDP growth rate, the demand for electricity will also continue to grow. Under normal economic conditions (GDP growth rate of 4% -5.5%), the average electricity demand growth from 2023 to 2047 is 4.8%, and the average peak demand growth is 5.1%.

Promotion of renewable energy projects: The Pakistani government has initiated the construction of multiple renewable energy power projects, involving a total of 16 projects with a total installed capacity of 860 megawatts. These projects are expected to be connected to the grid by the end of this year. In addition, the Pakistani government has also planned three batches of renewable energy power projects, with the first batch consisting of 19 projects and a total installed capacity of 531 megawatts.

However, although Pakistan's electricity demand continues to grow, it also faces some challenges. In order to better meet the growing electricity demand, Pakistan needs to further develop and implement more renewable energy projects, and seek more international cooperation and technical support to achieve sustainable electricity supply.

The power transformer market in Pakistan has experienced rapid growth and changes in the past few years.

The following is an overview of the power transformer market in Pakistan by Martin, Sales Director of Hengfengyou:

Market size: The Pakistan power transformer market has experienced significant growth in the past few years. This is mainly due to the increase in infrastructure construction and electricity demand in the country. According to different statistical data, the power transformer market in Pakistan has grown at an annual rate of 20% to 30% in the past few years.

Main suppliers: The power transformer market in Pakistan is dominated by several major suppliers. These suppliers include domestic transformer manufacturers such as Exxon and Punj Lloyd, Hengfengyou Electric, as well as some internationally renowned power equipment manufacturers such as Siemens and General Electric. These companies have a significant market share in the transformer market in Pakistan.

Product Type: The main types of transformers sold in the Pakistani power transformer market include oil immersed transformers, dry type transformers, and epoxy cast transformers. Among them, oil immersed transformers are the most commonly used type and are widely used in various power facilities. Hengfengyou Electric recently exported two 330kV, 200MVA oil immersed transformers in Pakistan. At present, the operation is good and the quality is reliable, which proves the Hengfengyou transformer（ hfy@hengfengyou.com ）.

Application field: Power transformers have been widely used in various fields in Pakistan. Some of the main application areas include transmission and distribution, industrial facilities, commercial buildings, and residential buildings. With the continuous increase in infrastructure construction and electricity demand, the demand for power transformers will continue to grow.

Market competition: The power transformer market in Pakistan is fiercely competitive. All suppliers are striving to improve product quality, reduce costs, and provide customers with higher quality services. In market competition, in addition to product price and quality, supplier after-sales service is also one of the important factors that customers consider.

Policy environment: The Pakistani government has carried out continuous reforms and investments in the power industry to address the issue of power supply shortages. These policies include strengthening power infrastructure construction, encouraging private investment, and promoting renewable energy. The implementation of these policies will provide more opportunities and potential for the power transformer market.

Future trend: With the continuous development of Economy of Pakistan's economy and the continuous growth of power demand, the market demand for power transformers is expected to continue to increase. The future development trends may include more efficient transformer technology, more environmentally friendly transformer materials, and the application of smart transformers. In addition, with the development of new energy, the demand for renewable energy transformers such as wind and solar energy in new energy power stations will also increase.

Oil immersed transformers have the following technical characteristics:

Compact structure, small size, and light weight. This type of transformer adopts an autoregressive step-down dry type transformer, which has advantages such as strong overload capacity, low temperature rise, and convenient operation and maintenance.

Low loss. The transformer adopts a multi tap connection method to connect, making the turn ratio of each tap greater than 1, thereby increasing the coupling coefficient between windings and reducing no-load losses.

Flexible and easy to install and maintain. The transformer adopts a multi tap connection method, making the arrangement of the entire winding more flexible and convenient for on-site installation and maintenance work.

The oil immersed transformer also adopts a three-phase combination transformer, which introduces the three-phase symmetrical components into their respective measuring instruments or protective devices through their respective identical terminals.

The oil immersed transformer uses copper wire or foil on the low-voltage winding, while the high-voltage winding is filled and wrapped with fiberglass felt and cast with epoxy resin, ensuring high mechanical strength and low partial discharge.

The iron core clamp of the oil immersed transformer has a special anti-corrosion protection layer, which can withstand short circuits and lightning impacts.

The oil immersed transformer is equipped with a pressure relief valve with a voltage range of 30-2000kVA, which can ensure the safety of the equipment in case of excessive pressure.

Oil immersed transformers can also be equipped with gas relays with alarm and trip terminals according to user needs, which increases their functionality.

The glass thermometer on the top of the oil tank and the outdoor signal thermometer equipped with this transformer can ensure the accuracy of temperature measurement, making it safer and more stable during operation.

In summary, oil-immersed transformers are widely used in the field of transmission and distribution, with advanced design, high-quality materials, scientific formula, strict technology, and high guarantee, which can meet various complex power needs
