structure
Features:
Based on the traditional structure and mature technology, our company has made many improvements, such as:
1) Spiral coil with longitudinal oil passage, better internal heat dissipation;
2) Improved the effective support of the coil end surface, and the ability to resist short-circuit current is stronger;
3) The new hoisting structure and body positioning structure are adopted to ensure more reliable in long-distance transportation and operation;
4) We have many unique and reliable structures to serve you;
5) Selecting a transformer with a higher performance level will have a higher level of technical content.
