Power Distribution Transformer--TRANSFORMADOR TRIFASICO TIPO POSTE
1. General Introduction
The Power Distribution Transformer is a critical component in electrical grids, responsible for stepping down high-voltage electricity from transmission lines to lower voltages suitable for end-user applications. Designed to ensure reliable, efficient, and safe power delivery, these transformers play a pivotal role in residential, commercial, and industrial settings. Available in various configurations, including dry-type and oil-immersed models, they adapt to diverse environmental and operational requirements.
2. Technical Parameters
3. Key Features
3.1 High Efficiency
- Utilizes low-loss silicon steel cores and optimized winding designs to minimize no-load and load losses, reducing operational costs and carbon footprint.
- Meets international energy efficiency standards (e.g., IE3, IEEE C57).
3.2 Reliable Insulation
- Dry-Type Transformers: Employ epoxy resin casting or vacuum pressure impregnation (VPI) for excellent moisture resistance, fire safety, and long-term durability. Ideal for indoor installations.
- Oil-Immersed Transformers: Feature mineral oil insulation with high dielectric strength, providing enhanced cooling and protection against electrical faults. Suitable for outdoor and heavy-duty applications.
3.3 Safety & Protection
- Equipped with built-in protection mechanisms, including overcurrent, overvoltage, and over-temperature relays.
- Oil-immersed models include Buchholz relays and pressure relief devices to prevent internal faults and oil leakage.
3.4 Adaptable Design
- Available in single-phase or three-phase configurations to suit different load requirements.
- Offers customizable tap changers for ±2.5% or ±5% voltage regulation, ensuring stable power supply under varying grid conditions.
3.5 Low Noise Operation
- Advanced core lamination and vibration-damping technologies reduce mechanical noise, making it suitable for noise-sensitive environments such as residential areas and commercial buildings.
4. Applications
- Residential Power Distribution: Steps down high-voltage grid power to 230V/400V for household use.
- Commercial Buildings: Powers offices, shopping malls, hospitals, and other facilities with reliable medium to low-voltage electricity.
- Industrial Settings: Supplies electricity to factories, manufacturing plants, and industrial parks, supporting heavy machinery and equipment.
- Renewable Energy Integration: Connects distributed generation sources (e.g., solar farms, wind turbines) to the grid.
- Urban and Rural Grids: Enhances grid stability and power quality in both urban and remote rural areas.
