33KV 35KV High Voltage Electricity Power Distribution 2000kVA 3150kVA Step Down Oil Immersed Electric Transformer
33KV 35KV High Voltage Electricity Power Distribution 2000kVA 3150kVA Step Down Oil Immersed Electric Transformer is a reliable and efficient solution designed for modern industrial and utility power systems. It is widely used in power distribution networks, industrial facilities, renewable energy projects, infrastructure, and utility substations.
This oil-immersed step-down transformer is engineered to reduce high voltage (33kV/35kV) into medium or low voltage levels, ensuring safe, stable, and efficient power supply for heavy-duty applications.
⭐ Key Features & Advantages
- High Efficiency & Low Loss – Optimized electromagnetic design with high-grade silicon steel core reduces no-load and load losses.
- Robust & Reliable – Oil cooling system provides superior insulation and heat dissipation, guaranteeing long-term stable performance.
- Wide Applications – Suitable for power utilities, factories, mining, renewable energy, and large-scale infrastructure projects.
- Customizable Design – Available in different voltage levels, capacity ranges (2000kVA, 2500kVA, 3150kVA, etc.), vector groups, and protection systems.
- International Standards – Manufactured in compliance with IEC, ANSI, ISO, and CE certifications.
