Robust Performance for Demanding ApplicationsDesigned for voltage boosting in power transmission and distribution, this step-up transformer excels in high-load scenarios. Its advanced insulation (Class F or H) and double-wound construction ensure extended durability and stable performance, even under varied ambient humidity up to 95%. Supported by air or oil cooling options, it accommodates operational temperatures from -25C to +70C.
Reliable Construction Using Quality MaterialsUtilizing metal housing and a CRGO silicon steel core, this transformer is constructed for longevity. The coils are available in copper, aluminum, or other materials as per requirement, and the anti-corrosive PU paint finish enhances protection against environmental factors. Each unit is floor-mounted for stability, with dimensions tailored to capacity.
Compliance with Industry StandardsEngineered according to IS 2026 and IEC 60076 standards, this transformer guarantees safety and performance. Adjustable tap changers (on load/off load) allow seamless voltage regulation. Low noise levels at less than 60 dB make it suitable for installation near sensitive equipment or in public utility spaces.
FAQ's of Step-up Transformer:
Q: What is the primary function of this step-up transformer?
A: The main function is to boost voltage from a lower level (e.g., 415 V) to a higher level (up to 33 kV) for efficient power transmission and distribution, thereby minimizing energy loss over long distances.
Q: How is the transformer protected against environmental hazards?
A: It features a robust metal enclosure, an anti-corrosive PU paint finish, and optional protection classes (IP23/IP54) to safeguard against dust, water, and corrosive elements, ensuring reliable operation even in harsh environments.
Q: Where should the transformer be installed?
A: This transformer is designed for indoor or outdoor floor mounting at substations, power plants, industrial facilities, or any site requiring high-voltage power distribution. The mounting and protection features make it suitable for diverse applications.
Q: What cooling methods are available for this transformer?
A: The transformer supports both air-cooled and oil-cooled configurations. You can choose the ideal cooling method based on your application's requirements, environmental conditions, and load levels.
Q: When should an on-load or off-load tap changer be used?
A: Tap changers help regulate output voltage. On-load tap changers are used if voltage adjustment is needed without interrupting the supply, while off-load tap changers are suitable if adjustments are made during maintenance or low-demand periods.
Q: What are the benefits of using CRGO silicon steel for the transformer core?
A: Cold Rolled Grain Oriented (CRGO) silicon steel provides superior magnetic properties, resulting in reduced core losses and improved efficiency. This enhances overall transformer performance and extends its operational life.
Q: How efficient is this transformer and what standards does it meet?
A: The transformer achieves an efficiency above 98%, meeting or exceeding IS 2026 and IEC 60076 standards for electrical performance, load loss, and safety.
