Outdoor Oil Immersed Power Transformer High-Voltage 200KVA/400KVA Three-Phase 15KV/6KV Input 415V/380V for 208V Applications

Overview of Outdoor Oil Immersed Power Transformer High-Voltage 200KVA/400KVA Three-Phase 15KV/6KV Input 415V/380V for 208V Applications

An oil-immersed transformer is a type of electrical transformer where the core and windings are submerged in an insulating oil. This oil serves two primary functions: it acts as a highly effective insulator between conductive parts and as a coolant to dissipate heat generated during operation. These transformers are robust, reliable, and highly efficient, making them the standard choice for high-voltage power distribution and transmission networks, typically installed outdoors in substations.

Features of Outdoor Oil Immersed Power Transformer High-Voltage 200KVA/400KVA Three-Phase 15KV/6KV Input 415V/380V for 208V Applications

• Effective Cooling: The insulating oil efficiently absorbs heat from the core and windings and transfers it to the radiator fins, allowing for natural or forced circulation and higher overload capacity.
• Superior Insulation: The oil provides much better dielectric strength than air, allowing for a more compact design for a given voltage rating and protecting against short circuits.
• Robust Construction: Designed for long-term, reliable operation (often 25-30 years) in harsh outdoor environments.
• Overload Capacity: Can handle temporary power overloads better than dry-type transformers due to the thermal mass and cooling properties of the oil.
• Protection System: Equipped with a conservator tank (to allow for oil expansion), breather (to absorb moisture from air), and protective relays (Buchholz relay) for internal fault detection.
• Cost-Effective: Generally more economical for high-power applications compared to dry-type transformers.

This transformer steps down high voltage for commercial and industrial sites needing 208V power. It’s built for outdoor use. Oil cools the transformer effectively. You can choose between two power sizes: 200KVA or 400KVA. Both handle three-phase electricity.

It accepts high input voltages. Standard inputs are 15,000 volts (15KV) or 6,000 volts (6KV). The output provides a lower voltage. Standard outputs are 415 volts or 380 volts. This output is specifically designed for equipment requiring 208 volts. This setup connects easily to existing 208V systems.

The transformer sits inside a strong welded steel tank. This tank protects the core and coils inside. The tank is sealed tight. This prevents oil leaks. It also keeps moisture and dirt out. The tank has fins or tubes. These increase the surface area. This helps the oil cool down faster. Natural air flow cools the oil. No fans are needed. This makes it quiet and reliable.

Safety is important. The tank includes pressure relief. This protects against internal faults. Overpressure vents safely. An oil level gauge is visible. This shows the oil amount clearly. Operators check it easily. Fill and drain valves are standard. These allow for oil changes or sampling. Lifting lugs are welded on. These make moving and installing the unit straightforward.

Installation is simple. Place it on a solid, level pad. Ground the tank securely. Connect the high-voltage and low-voltage cables correctly. The robust steel construction withstands harsh weather. Rain, snow, wind, and sun won’t damage it. Regular maintenance involves checking the oil level and looking for leaks. Keep the tank exterior clean.

This transformer is ideal for many places. Factories, warehouses, shopping centers, and office buildings use it. It reliably powers motors, lighting, HVAC systems, and other machinery needing 208 volts. It provides stable power conversion from the utility feed.

Applications of Outdoor Oil Immersed Power Transformer High-Voltage 200KVA/400KVA Three-Phase 15KV/6KV Input 415V/380V for 208V Applications

These heavy-duty outdoor oil-immersed power transformers handle the tough job of stepping down high voltage electricity safely. They take incoming power at 15,000 volts or 6,000 volts. They convert this down to usable levels like 415 volts, 380 volts, or specifically 208 volts. The common sizes are 200KVA and 400KVA. They are built for three-phase electrical systems, the standard for industrial and commercial power.

You find these transformers mounted outside buildings or substations. They are essential wherever high voltage transmission lines meet local power needs. Think factories needing reliable machinery power. Think large commercial buildings running lighting, HVAC, and equipment. They are vital for new construction projects requiring power distribution. They are also key for upgrading older electrical infrastructure.

The transformer core and windings sit inside a strong welded steel tank filled with insulating oil. This oil does two critical jobs. It cools the transformer during operation. It also insulates the internal components, preventing dangerous short circuits. The sealed tank protects the oil from weather and contamination. This design ensures reliable operation year-round. It withstands rain, snow, dust, and temperature swings.

These units provide a dependable link between the high-voltage grid and your facility’s lower voltage equipment. Their robust construction means minimal maintenance. They are designed for a long service life in harsh outdoor conditions. The oil insulation and cooling system manage heat effectively. This prevents overheating under load. Safety features are built-in. They help protect both the electrical system and personnel. Using these transformers ensures stable voltage supply for sensitive 208V equipment. They are a fundamental part of efficient power distribution networks.
