Transformers for Power Generation and Transmission

Power Generation and Transmission

Ideal transformer solutions for power plants are available. It can be used in power plants to increase the voltage of electricity produced by the plant before sending it to the grid and is also used in transmission and distribution to increase or decrease the voltage of the electricity delivered from the power plant to homes and businesses.

Transformer for railway

Railways and Transportation

Power transformers are used in railway and transportation systems to provide electricity to trains, trams and electric buses. Step-down transformers can step down the voltage level of the incoming power supply to the lower voltage levels required by the various electrical and electronic systems on the train.

Transformer in buildings

Commercial and Residential Buildings

Step-up and step-down transformers can distribute power and regulate voltage for lighting, heating, cooling and other electrical systems, and are suitable for commercial and residential buildings.

Transformer for audio systems

Audio Systems and Electronics

In audio systems, step transformers are used to step up or step down voltage before sending it to speakers. It applies to electronic equipment including computers, televisions, radios and cell phones.

Transformer for medical system

Medical Systems

Transformers ensure electrical isolation, protect patients and medical personnel from electric shock, and also regulate and stabilize the voltage. From isolated power systems in operating rooms to imaging equipment such as X-ray machines and MRI scanners, isolation power transformers are an essential component for reliable and safe power distribution in medical systems.
