Customized Main Power Transformer (16000kVA-100MVA)

Our main power transformers are engineered for high-capacity power transmission and regional substations. We provide tailor-made electrical design—from impedance matching to cooling optimization—ensuring perfect compatibility with your specific grid requirements.

Product Highlights

• Tailor-Made Engineering: Custom-designed to fit your project's voltage, capacity, and site conditions (IEC/IEEE/ANSI compliant).
• Ultra-Low Loss Design: High-permeability core materials reduce energy loss by 20%–40%, significantly lowering your long-term operating costs.
• Rugged Reliability: Leak-proof tank construction and advanced insulation systems built to survive extreme temperatures, high humidity, and heavy-load demands.
• Smart-Grid Ready: Pre-configured for SCADA integration and real-time monitoring (DGA, Temperature, Pressure), turning your substation into a smart power node.
• Factory-Validated Quality: Every unit undergoes a full suite of routine and type tests (including lightning impulse & short-circuit tests) before shipment.

Typical Structure

• Advanced Core Architecture: Constructed with high-permeability cold-rolled grain-oriented silicon steel featuring optimized step-lap joints. This minimizes no-load losses and reduces operational noise to exceptionally low levels.
• Precision Windings: Multi-layer cylindrical copper windings with reinforced vertical oil ducts. This design dramatically enhances heat dissipation and guarantees superior short-circuit withstand capability under fault conditions.
• Rugged & Durable Tank Design: Precision-welded corrugated radiator tanks with multi-layer surface treatment (acid pickling, phosphating, and advanced industrial painting). Engineered to withstand harsh environments and long-term outdoor exposure.
• Intelligent Monitoring Ready: Each unit is pre-configured for integration with modern SCADA systems, enabling real-time monitoring of oil temperature, pressure, and gas composition (DGA).
• Comprehensive Quality Assurance: Every transformer undergoes a full suite of routine and type tests (including lightning impulse and short-circuit withstand tests) in our laboratory, ensuring absolute compliance with international and local standards.

Typical Key Parameters
