Transformador de potencia trifásico de doble devanado de 220 kV

Key Advantages/Features

High Voltage Transmission/Transformation Capacity — Suitable for high-voltage (220 kV and above) transmission and transformation systems, it is a crucial piece of equipment for large-capacity power transmission, urban/regional power grid backbones, and inter-regional power transmission.

High Efficiency & Low Loss — Excellent core and winding design reduces magnetic and load losses, helping to minimize energy loss during transmission and transformation, thus improving economic efficiency.

Stable, Reliable, and Long Lifespan — Oil immersion + sealing + high-quality insulation + rigorous structural design provide excellent electrical insulation, mechanical stability, and short-circuit withstand capability, suitable for long-term operation (typically decades).

Flexible Output & Voltage Regulation Capability — With the aid of a tap changer, voltage regulation can be applied to the high-voltage side (input) to cope with grid voltage fluctuations and ensure stable low/medium voltage output. Adaptable to grid load changes and voltage instability.

Wide range of applications — It can be used in various scenarios such as substations, regional/city grid backbone transmission, urban power distribution, power supply for medium and large industrial parks/factories and mines, and renewable energy access (wind power, photovoltaic grid connection).

Typical Application Scenarios

**High-Voltage Transmission & Transformation:** Transforms/steps down high-voltage (220 kV) electricity from power plants and long-distance transmission lines for transmission to medium-voltage/low-voltage distribution networks.

**Regional/Urban Backbone Power Grids:** Serves as the backbone of urban/regional power grids, enabling large-capacity, multi-user, and stable power supply.

**Large Industrial Parks/Heavy Industry/Mines/Factories:** Locations with high power demand, high stability requirements, and large load fluctuations.

**Renewable Energy/Generation Grid Connection:** Used in wind power, solar power, and hybrid energy systems to integrate/step up/step down high-voltage (or medium-voltage) electricity from generation terminals for grid connection.

**Inter-regional/Inter-grid Transmission and Dispatch:** A combination of high-voltage transmission lines and transformers used for long-distance power transmission, inter-regional grid interconnection, backup, or peak shaving.
