Power Transformer Manufacturer

Power transformers are key components in power networks. Their availability and longevity have a major impact on grid reliability and profitability. Firstly, let me tell you “what is transformer”? Transformer is an electrical device which transfers one electrical circuit to one or more circuit. Mainly, Transformer is used to increase or decrease voltage into circuit as per the requirement. It works on the principle of Faraday’s law of Electromagnetic Induction which states that “the magnitude of voltage is directly proportional to the rate of change of flux.” Now let me acquaint you with Power Transformer.

Power Transformers are used to “transform” voltage from one level to another, usually from a higher voltage to a lower voltage. They do this by applying the principle of magnetic induction between coils to convert voltage and/or current levels. Generally, the higher voltage falls into the range of 11-22-33kV whereas lower voltage into 250 or 433V range. The frequency remains identical before and after the transformation of the current.

We, Tirupati Transformers are always proceeding towards development by providing quality products to our customers. Considering the modern technology, we construct our transformers as per international & National standards. We are one of the leading power transformer manufacturers in Delhi, NCR. To earn goodwill in the transformer industry, our key objective is to provide the best services for our customers so that sustainable relationships can be maintained.

Power transformers are generally used in transmission network for stepping up or down the voltage level. It operates mainly during high or peak loads and has maximum efficiency at or near full load. Being a power transformer manufacturer, Tirupati transformers have manufactured a tried and tested products that works best under any condition and accuracy that leads to perfection.

We are trying our best to be the winner in the race to become one of the best power transformer suppliers. For this, Tirupati transformers have strictly followed their tag line i.e. Epitome of quality. We launch our product with many technical specifications that have evolved over time supported by practice and proficiency in transformers.
