Versatile Cooling and Mounting OptionsOur transformers offer flexible cooling modesONAN (Oil Natural Air Natural) and ONAF (Oil Natural Air Forced)to ensure optimal performance in varying load conditions. With pole, pad, and indoor mounting types, these units suit a wide range of installations and environments. Each transformer is designed to meet site-specific requirements while maintaining efficiency and durability.
Advanced Safety and Protection StandardsSafety is paramount with our transformers, equipped with safeguards against overload, short circuit, and lightning strikes. Protection ratings of IP23 or IP44 provide robust defense against environmental hazards. All models are certified to both national and international standards (BIS, IEC, IS), guaranteeing reliability and safety during operation.
Custom Engineering and EfficiencyEvery transformer can be tailored for specific dimensions, connection types (Delta/Star or customized), and operating voltages up to 33 kV. Constructed from high-grade CRGO silicon steel cores and available with copper or aluminium windings, our units reach efficiencies of up to 98%, making them ideal for high-performance industrial and commercial applications.
FAQs of Power Phase Transformer:
Q: How does the ONAN and ONAF cooling system benefit transformer performance?
A: ONAN (Oil Natural Air Natural) and ONAF (Oil Natural Air Forced) cooling systems enhance transformer operation by efficiently dissipating heat. ONAN relies on natural convection, making it suitable for moderate loads, while ONAF utilizes forced air for higher cooling capacity, allowing the transformer to handle greater power demands without overheating.
Q: What customization options are available for Power Phase Transformers?
A: Customers can request customizations in dimensions, winding material (copper or aluminium), mounting type (pole mounted, pad mounted, or indoor), connection (Delta/Star or as specified), and protection degrees (IP23 or IP44). This ensures the transformer perfectly aligns with installation requirements and operational needs.
Q: When should I choose a transformer with an On Load Tap Changer versus an Off Circuit Tap Link?
A: An On Load Tap Changer is ideal when voltage adjustments are needed without interrupting the transformers operation, commonly required in fluctuating load scenarios. An Off Circuit Tap Link is suited for applications where voltage is set during maintenance outages. The choice depends on how frequently voltage regulation is necessary during use.
Q: Where can these transformers be installed, and what environments are they suitable for?
A: These transformers are designed for a wide range of environments, including outdoor (pole and pad mounted) and indoor settings. Engineered to operate reliably within ambient temperatures from -25C to +50C, they are well-suited for industrial facilities, commercial complexes, and power distribution networks.
Q: What protective features are integrated in these transformers?
A: Each transformer includes safety mechanisms covering overload protection, short circuit defense, and resilience against lightning strikes. Additionally, the robust IP23/IP44 enclosure ratings safeguard against dust and water ingress, ensuring continued operation even in challenging environments.
Q: How does the use of high-grade CRGO silicon steel in the core enhance efficiency?
A: High-grade Cold Rolled Grain Oriented (CRGO) silicon steel minimizes core losses, significantly improving overall transformer efficiency. This material supports lower energy consumption, reduced heat generation, and helps the transformer achieve efficiency levels up to 98%.
Q: What standards and certifications do these transformers comply with?
A: All models are manufactured according to BIS, IEC, and IS requirements, specifically adhering to IS 2026 and IEC 60076 standards. These certifications affirm quality, safety, and reliability for both domestic and international applications.
