Product Description
Transformers are electrical devices used to increase or decrease AC voltage according to the application requirements. They provide electrical isolation between circuits and are widely used in power generation, transmission, and distribution systems. Transformers are also essential in electronic equipment, chargers, UPS systems, industrial control panels, and various electrical devices to provide the required voltage safely and efficiently.Superior Safety and Protection Features
This power transformer incorporates advanced protection mechanisms such as Buchholz relay, oil temperature indicators, and pressure relief devices. These safety features minimize risk during operation and ensure longevity, reducing the chances of failure and facilitating reliable service in demanding environments.
Enhanced Performance and Versatility
The transformer provides high efficiency (98% or above), flexible tap ranges (+/- 2.5% or 5%), and customizable voltage connections to suit varied industrial and utility requirements. It can be configured with on-load or off-circuit tap changers according to your application, ensuring seamless power regulation.
Durability and Environmental Adaptability
Manufactured using cold-rolled grain-oriented steel laminations and corrosion-resistant epoxy or PU paint coatings, this transformer withstands harsh weather and demanding site conditions. With IP20-IP23 protection and seismic resistance available, it operates reliably at altitudes up to 1,000 meters and in temperatures from -20C to +50C.
FAQ's of Power transformer:
Q: How does the power transformer adapt to different voltage and capacity requirements?
A: Our transformer supports rated voltages from 11 kV up to 33 kV, with capacities between 100 kVA and 2,500 kVA or more, depending on design. It offers customizable winding connections such as Dyn11 or Yyn0 and flexible tap ranges (+/-2.5%, +/-5%) to match application-specific requirements.Q: What safety and protection devices are included with the transformer?
A: The transformer is equipped with essential safety components like the Buchholz relay, oil temperature indicator, and pressure relief device. These features promptly alert operators to internal faults and thermal anomalies, ensuring safe operation and helping to prevent major equipment damage.Q: When is it necessary to specify high seismic withstand capability for the transformer?
A: High seismic withstand features are necessary when the transformer is to be installed in regions prone to earthquakes or where specific site requirements demand it. We offer transformers with built-in seismic resistance to ensure continued operation during and after seismic events.Q: Where can this transformer be installed and used effectively?
A: Designed for both indoor and outdoor deployment, our transformer features weather-resistant coating, enclosure protection (IP20 - IP23), and operates reliably at altitudes up to 1,000 meters and ambient temperatures up to +50C, making it well-suited for diverse climates and environments across India and abroad.Q: What is the process for maintaining the transformer's insulating oil according to standards?
A: The transformer uses high-quality mineral insulating oil compliant with IS 335 or equivalent. Periodic oil testing and filtration are recommended to maintain dielectric strength and prevent moisture or contaminant buildup, thus ensuring optimal insulation and long-term reliability.Q: How does this transformer benefit electrical distribution networks?
A: With an efficiency rating above 98%, low noise level (<65 dB at 1 meter), robust construction, and customizable design, the transformer reduces energy losses, enhances operational reliability, and supports stable, safe power supply for industrial, commercial, and utility sectors.Tell us about your requirement
