High-Temperature & Acid-Resistant Composite Insulator Core Rods

Taporel’s High-Temperature and Acid-Resistant Composite Insulator Core Rods offer not only exceptional mechanical and electrical properties but also superior stress-corrosion resistance integrated into our high-temperature resistant formula.

Our core rods have successfully passed a 7,200-hour stress-corrosion resistance test, vastly exceeding the industry standard requirement of only 96 hours. This makes our products a leader in long-term reliability for harsh environments.

Applications & Environments

These core rods are compatible with various composite insulator manufacturing processes, especially injection molding. We strongly recommend using our high-temperature and acid-resistant rods for insulators installed in:

• High-pollution areas (Industrial zones, coastal regions).

• Regions prone to acid rain.
