What Functions Does a Power Transformer Fulfill?

What Is The Purpose Of Power Transformer?

The core function of power transformers is to realize efficient and safe power transmission and distribution in electrical systems. It mainly completes voltage conversion and adjusts voltage levels to meet different needs. In the process of long-distance power transmission, it will raise the low voltage of the generator to a high voltage to reduce the current, thus reducing the power loss in the transmission line. When the power reaches the user terminal, it reduces the high voltage to a low voltage (e.g., 220 volts for household use), ensuring that it can meet the daily and industrial power demand. At the same time, it also provides electrical isolation function, cutting off the spread of fault current to protect equipment and personnel, thus stabilizing the power supply.

When to Use a Power Transformer?

It is used in multiple scenarios. In long-distance power transmission, to reduce line loss, transformers raise voltage. At user ends, such as residential areas, factories, and commercial buildings, they lower high voltage to usable low voltage. Also, in situations needing impedance matching (to maximize power transfer) or electrical isolation (to avoid fault propagation), power transformers are essential.

Shuangfeng Transformer Products.

Zhejiang Shuangfeng Electrical Co., Ltd. is a professional transformer manufacturing factory that provides reliable services to customers. The transformer is manufactured using high-quality raw material procured from the most reputed vendors in the industry.

Several features like easy installation and low maintenance cost ensure optimum performance under unfavorable weather conditions for long durations. Here are some of the Zhejiang Shuangfeng Electrical Co., Ltd.  power transformer products.

Dry-type transformer

We developed SC9, ScB9 series and SC10, SCB10 series padding thin-insulation dry-type distributing transformer whose winding is sealed up with epoxy, therefore theresin insulating drytype transformer is flame-retardant, explosion-proof, free from maintenance and pollution, and it is compacted and can go deep into load center. Besides, with scientific and reasonable design and coating craftwork, it has advantages of low partial discharge capacity, low noise, good heat dispersion and it can run over a long time withl40% rated load in the circumstance of cold wind. It applies intelligent thermal controller and has the functions that it will alarm when there is fault or the temperature is exceeded and switch off as well as the function of "black box". It can be monitored and controlled by connecting it to the computer through its RS485 serial interface. Therefore, it is widely used in the places such as hotel, restaurant, airport, power plant, hospital, skyscraper, shopping center, and residential areas and other adverse environments like subways, smelt and power plant, shiP, offshore drilling platform, etc.

Oil-immersed transformer

The three-phase oil-immersed distributing transformer applies new type insulatingstructure and makesshort-circuit resistance strong The iron core is made of high-qualitycold-rolled silicon-steel plate. High-voltagewinding group is made up of high-qualityoxygen-free copper lines and it adopts multilayered drum typet sructure. All fastenershave been processed with special treatment to prevent them from loosening.

As high-tech product that promoted bv the county, the product has many advantagessuch as high efficiency, low loss. lts social benefits are remarkable that it will save muchof electricity consumption and operating cost.
