Technical Tables

Drawing

The 35kV power transformer developed by our company is engineered using proprietary calculation and verification systems. Comprehensive optimization and rigorous validation are applied to key components including the core, windings, active parts, lead structures, and tank assemblies to ensure superior performance and reliability.

Leveraging advanced manufacturing technologies, precision equipment, and high-grade materials, the transformer features a compact structure, reduced weight, low energy losses, minimal partial discharge, and low operational noise. The product demonstrates excellent electrical and thermal performance, delivering stable and reliable operation under various service conditions.

Key Technical Advantages:

High-efficiency electromagnetic design, significantly reducing no-load and load losses

Low partial discharge and noise levels, meeting modern environmental and operational standards

Precision process control, enhancing mechanical integrity and thermal stability

Strict material selection and quality management, ensuring long-term operational safety

Standardized and modular design, facilitating installation, maintenance, and mass production

This series of transformers is widely used in transmission and distribution systems, and is ideally suited for substations, industrial zones, and renewable energy integration. It provides outstanding economic and environmental benefits while supporting low operating and maintenance costs.
