Product Overview

3500 KVA Pad Mount Step Up Transformer - 480V Delta Primary - 13200Y/7620 Grounded Wye Secondary - KNAN/Bell Green is a product intended for professional commercial and industrial applications.

Key Specifications

• Temperature Rise: This unit features 65°C temperature rise for reduced heat waste, increased reliability, and longer life. At 65°C temperature rise, the transformer offers 3500 KVA (3.5 MVA). The transformer meets DOE 2016 efficiency standards. 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-PML-R4-3P-DE-3.5MVA-GMQ-LT-DF-A6-BB-CS-2B6-T8-M2 features biodegradable cooling fluid (KNAN) with a capacity of 660 gallons. We offer transformers with FR-3 oil fluid, if needed.
• 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/Valves: The following gauges are included with the system: liquid level gauge with alarm contacts, thermometer with two alarm contacts (1 NO and 1 NC each), pressure/vacuum gauge with bleeder and contacts, winding temperature indicator with four NO contacts, pressure relief valve, SST upper filter press valve, drain valve with sampler port, and fault indicator provision.
• Fault Pressure Devices: This transformer features an automatic action fault pressure device. Fault pressure devices are used to detect high rates of pressure rise within the tank.
• Rapid Rise Relay: There is a rapid rise relay on this 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 high elbow surge arresters on the secondary (medium voltage) side. Designed for over-voltage and transient voltage protection, the components prevent damage caused by lightning, internal switching or voltage surges. We can offer models without high elbow surge arresters that have mounting provisions for customer-provided surge arresters.
• Load Breaker Switch: The MT-PML-R4-3P-DE-3.5MVA-GMQ-LT-DF-A6-BB-CS-2B6-T8-M2 is equipped with a 2-position, 200-amp LBOR transformer switch, a 2-position, 200-amp LBOR line A switch, and a 2-position, 200-amp LBOR line switch B. The load break switches are located on the secondary (medium voltage) side.
• Protection Fuses: This transformer has three fused bayonets with no isolation link, three oil retaining valves on the bayonets, and six parallel oil-immersed partial range current limiting fuses on the secondary (medium voltage) side.
• Mount: The heavy-duty, 304 stainless steel enclosure makes the unit suitable for both indoor and outdoor applications. This power distribution system can be pad mounted on concrete pads.
