Tier-2 2500 kVA Split Transformer-10500 Delta Primary, 690-690Delta Secondary

Daelim Transformer is a robust transformer manufacturer with multiple production lines, including Pad Mount Transformers, ECO Transformers, Substation Power Transformers, Dry Type Transformers, Pole Mount Transformers, and more. Our primary focus is on providing comprehensive support and services for transformer projects across Europe, America, and Australia.

In May 2024, we delivered this 2500 kVA split transformer to our Danish customer for a local energy storage project. This transformer is a three-phase transformer featuring 6 bushings for low-voltage double split. The primary voltage is 10500V Delta, with secondary voltages of 6900V Delta and 6900V Delta. The transformer winding connection group is Dd0d0, with a frequency of 50 Hz, cooling method of ONAN, and impedance of 5.75%. At its rated capacity of 2.5 MVA, the sound level is 63 dB. The insulating liquid utilized is highly refined non-PCB mineral oil.

This transformer embodies advanced design concepts and employs high-quality core, winding materials, and components, ensuring exceptional insulation performance, high efficiency, safety, and reliability. It has successfully met the stringent test requirements for CE certification, holding a CE certificate and fully complying with and exceeding EU standards.

Transformer Features

• Compliant with EN60076 standard, boasting TIER-2 efficiency.
• Equipped with 6 LV bushings of epoxy resin shovel type, each featuring 6 holes.
• ATC LV bushing included for enhanced performance.
• Tank cover outfitted with 4 lifting rings for easy handling.
• High and low voltage electrostatic shielding, used to eliminate electromagnetic harmonic interference of solar energy.
• Pressure relief device situated on the top of the tank, capable of rapidly releasing significant pressure within the transformer, automatically reverting to its initial state without manual intervention.
• Liquid temperature gauge featuring two contacts; when the oil temperature exceeds 90℃, the system triggers an alarm and notification. If the temperature surpasses 105℃, the system automatically disconnects the transformer from the power grid to protect the transformer from damage.
• Liquid level gauge with two contacts, automatically alerting the remote monitoring system in the event of low or high oil levels.
• Pressure relief gauge for monitoring internal pressure.
• Upper fill valve for convenient fluid replenishment.
• Terminal block for connecting liquid level and temperature gauge contacts wires.
• No-load tap changer with 5 positions on the HV side, offering flexibility with rated voltages of 10500V and additional options including 10760V, 11020V, 10240V, and 9980V, catering to various operational requirements.
• Four groups of radiators, strategically positioned on both high and low voltage sides, facilitating efficient heat dissipation.
• Two ground pads on the LV side for enhanced safety.
• ATC HV bushing ensuring optimal performance.
• 3 HV bushings with porcelain construction and 4 holes each.
• 1 hand hole provided for convenient inspection and routine maintenance of the transformer.
