Product Overview

25 MVA Conservator Substation Transformer - 220000V Delta Primary, 47631Y/27500 Grounded Wye Secondary - ONAN/ONAF, Grey, NEMA 4X is a product intended for professional commercial and industrial applications.

Key Specifications

• Transformer Features: The industrial transformer features a primary voltage of three-phase 220000V Delta and a secondary voltage of three-phase
• Temperature Rise: This unit features 55°C temperature rise for reduced heat waste, increased reliability and longer life. At 55°C temperature rise, the transformer offers 25 MVA (25,000 KVA). The transformer meets standard efficiency requirements. The combination of low temperature rise and high efficiency makes this unit suitable for use in electrical rooms, air conditioned spaces in buildings, underground vaults, and similar locations, in addition to outdoor areas.
• Insulation Fluid: The MT-PSTC-R7-3P-DEXO-25MVA-GKZ-HT-LT-E6-AMF-CZ-2ZZ-M1 features
• Biodegradable Fluid: Biodegradable cooling fluid (vegetable oil) has a higher heat capacity compared to mineral oil, making the liquid safer to use and more reliable during operations. Vegetable oil has a higher flash point and fire point than mineral oil, hydrocarbon oil, silicone oil and synthetic ester. This cooling fluid is also non-toxic and can tolerate higher breakdown voltages than mineral oil. When operating at high temperatures, biodegradable cooling liquid sustains up to 120% loan conditions, which helps preserve the transformer's lifespan and performance.
• Gauges: The following gauges are included with the system: liquid level, temperature, fault indicator, and pressure/vacuum gauges. Standard liquid level, temperature, and pressure/vacuum gauges are analog, manual reading types.
• Fault Pressure Devices: There is a Buchholz relay fault indicator on this unit.
• Rapid Rise Relay: There are no rapid rise relays on the unit. This safety component is designed for protection when a rapid increase in tank pressure occurs. The relay is suitable for detecting sudden pressure fluctuations above predetermined safe limits.
• Surge arresters: This system comes with surge arresters on the primary side.
• Load Break Switch: The transformer is not equipped with a load break switch.
• Valves: The MT-PSTC-R7-3P-DEXO-25MVA-GKZ-HT-LT-E6-AMF-CZ-2ZZ-M1 is equipped with a pressure relief valve, fill valve, and drain valve with sampler port.
