Product Overview

Compared to traditional organic insulating materials, the insulation material used in the new ceramic-based aluminum foil reactor exhibits superior thermal aging resistance in long-term operating environments. Additionally, the improved overall heat dissipation performance results in a lower temperature rise. With its exceptional characteristics of high thermal conductivity, excellent heat dissipation, and resistance to both high and low temperatures, this product significantly extends the service life of the insulation material and provides greater flexibility in terms of capacity. As a result, it finds wide-ranging applications in fields such as new energy grids, high-speed railways, and subways.

Product Advantages

Features: The inorganic insulation exhibits significantly superior thermal and electrical aging resistance compared to conventional organic materials, effectively reducing the impact of partial discharge and inverse rectification on aluminum foil and windings, thereby markedly enhancing the reliability of the insulation material.

Load losses and coil temperature rise can be significantly reduced. Compared to conventional solutions, the temperature rise test shows a reduction of approximately 18%, providing additional design flexibility and offering superior performance compared to similar products.

Level-1 energy efficiency, low noise, fire-resistant, simple operation and maintenance, safe and reliable.
