introduction of 67kV three phase power transformer
GNEE TRANSFORMER supplies 67kV three-phase oil immersed power transformer.
Compliant with IEEE standards, the 67kV 8400kVA three-phase power transformer offers optimal efficiency and durability. With a primary voltage of 67kV (Delta) and a secondary voltage of 4.16kV (Grounded Wye), this transformer utilizes the ONAN (Oil Natural Air Natural) cooling method to maintain operational stability. Its Dyn1 vector group configuration ensures proper phase displacement, while the inclusion of DBF2-type fans enhances heat dissipation.
Housed in a NEMA 3R stainless steel control box, it's suitable for outdoor use. This oil type transformer operates efficiently under varying load conditions, providing stable voltage and a reliable power supply to connected systems.
67kV three-phase oil-filled power transformer Product Accessories
The transformer comes with a comprehensive set of accessories to ensure seamless operation and maintenance:
- Tap Changer: Equipped with a vacuum-type on-load tap changer for voltage regulation.
- Oil Level Gauge: Monitors oil levels to prevent operational issues.
- Cooling Fans: DBF2-type fans to enhance cooling efficiency.
- Control Box: NEMA 3R stainless steel control box for housing control devices.
- Surge Arresters: Protects against voltage spikes.
- Pressure Relief Device: Ensures safe operation under pressure variations.
- Winding Temperature Indicator: Monitors the temperature of windings to prevent overheating.
- Oil Temperature Indicator: Tracks oil temperature to maintain optimal performance.
- Vacuum Pressure Gauge: Measures internal pressure to detect potential issues.
- Lifting Lugs: Facilitates safe handling and transportation.
