About Three Phase Dry Type Transformer

Three Phase Dry Type Transformer are used to convert high voltage electrical current to low voltage electric current. These transformers are useful for electronic appliances and hi-tech machines. Integrated with modern technology, these transformers bring the level of the power supply that is required by the application. Composed of secondary and primary coils, the transformers offered by us show excellent runs ratio during their operation.

Superior Insulation & Construction

The transformer utilizes Class F/H insulation and durable mild steel enclosures, ensuring high thermal endurance and protection. Vacuum Pressure Impregnated (VPI) winding enhances mechanical strength and electrical reliability. This results in prolonged operation with minimal maintenance, making it ideal for industrial and commercial installations.

Flexible & Customizable Design

With capacities up to 2500 kVA and customizable voltage ratings, this transformer adapts to diverse application needs. Options for copper or aluminum coil materials and terminal types, along with tailored color choices, allow for seamless integration into your existing infrastructure. Output and voltage settings are adjustable as per the project requirements.

Operational Efficiency & Safety

Operating at an impressive 98-99% efficiency and equipped with overload and short-circuit protection, the transformer minimizes losses while safeguarding your equipment. Its self air-cooled (AN) design and low noise levels ensure that it meets international IEC standards for both performance and environmental impact.

FAQs of Three Phase Dry Type Transformer:

Q: How is the insulation class of this transformer beneficial for my application?

A: This transformer uses insulation Class F or H, which allows it to withstand higher operating temperatures. This increases durability, reduces the risk of thermal breakdown, and supports continuous operation in industrial or commercial environments.

Q: What is the mounting process and where can the transformer be installed?

A: The transformer is floor-mounted, making it suitable for indoor use in power distribution rooms, industrial automation settings, and commercial buildings. Its mild steel enclosure and IP23 protection ensure safe installation in controlled environments.

Q: When should I use off-circuit versus on-load tap changers?

A: An off-circuit tap changer is used when voltage adjustments are needed during transformer shut-down, suitable for stable load conditions. An on-load tap changer enables voltage adjustment during operation, ideal for applications subject to fluctuating voltage or load conditions.

Q: What safety features are included in this transformer?

A: The transformer includes overload and short-circuit protection to prevent damage from abnormal operating conditions. These features provide enhanced safety for both the equipment and connected systems.

Q: How does the Vacuum Pressure Impregnated (VPI) winding process enhance transformer performance?

A: VPI winding technique impregnates windings with insulating resin under vacuum and pressure, resulting in improved moisture resistance, mechanical rigidity, and dielectric strength. This ensures reliability and longer service life.

Q: What applications are ideal for this type of transformer?

A: This transformer is commonly used in power distribution networks, industrial automation processes, and commercial buildings due to its high efficiency, safety features, and customizable specifications.

Q: How can the transformers output or voltage be customized?

A: The output capacity and voltage settings can be tailored at the time of order to fit specific site requirements, including changes to high/low voltage ratings, tap changer options, enclosure colors, and terminal types.
