2 MVA Oil-Filled Power Transformer

The 2MVA oil-filled power transformers are engineered for high performance, reliability, and safety in demanding environments. Designed for a primary voltage of 11kV and a secondary voltage of 800V, these transformers are ideal for applications requiring robust power handling and long-term operational stability. With a design life of at least 25 years, they meet and exceed industry standards, ensuring dependable service across various applications.

Key Specifications:

• Type: Oil-Filled Power Transformer
• Rated Power: 2MVA
• Primary Voltage: 11kV
• Secondary Voltage: 800V
• Design Life: Minimum 25 years
• Cooling: Natural oil cooling
• Tap Changer: ±2×2.5% rated off-load taps
• Dielectric Fluid: Environmentally preferred, non-PCB, less flammable
• Protection Device: Detection, Measurement, and Control Relay (DMCR) with SCADA integration for remote monitoring and alarm functions

Features:

1. Enhanced Safety:

   • Non-Halogenated Windings: The windings are free from halogen compounds (chlorine, bromine, etc.), minimizing the risk of toxic pollutants and ensuring high safety standards in case of fire.
   • Environmental Protection: The insulating oil is free from Polychlorinated Biphenyls (PCBs) and selected for environmental friendliness and reduced flammability.

2. Robust Design:

   • Salt-Corrosion Resistance: Designed to withstand corrosive environments, especially in coastal areas, with special protection against salty air.
   • Quality Assurance: Comprehensive testing reports and conformance to all applicable standards and local regulations, including environmental and fire protection standards.

3. Advanced Monitoring and Protection:

   • DMCR Protection Device: Includes a DMCR for detecting gas emissions, overpressure, oil leakage, oil over-temperature, and winding over-temperature. Alarms are integrated with SCADA for remote monitoring and can trigger HV protective switchgear when necessary.
   • Maintenance Features: Equipped with a pressure relief valve, oil filling point, draining valve, sampling point, oil level and temperature indicators, and internal temperature sensors. Bunded to regulations for pollution control.

4. Installation and Safety:

   • Physical Protection: Transformer to be housed within an earthed fence or building to prevent accidental contact, with access restricted to authorized personnel only.
   • Ease of Installation: Provisions for installation by lifting, jacking, or rolling into position, ensuring flexibility and ease of handling.

5. Environmental and Regulatory Compliance:

   • Oil Catchment Systems: Includes systems for pollution control in case of oil leaks.
   • Temperature and Environmental Suitability: Transformer is selected based on installation method and site environment, with consideration given to maximum operating temperature. Forced ventilation or air conditioning is not required for enclosed units in suitable environmental conditions.

Accessories:

• Cable Box: 3-pole air-insulated, bottom entry, suitable for fully insulated dry terminations, with non-ferrous gland plate and IP68 CES-4 heat-shrink cable.
• Earthing Terminals: Included as required for safety.
• Pressure Relief Valve, Oil Indicators: For operational reliability and safety.

Applications:

• Suitable for various industrial and utility applications requiring robust and reliable power transformation and distribution, particularly in environments with challenging conditions.
