Supplier's note

  1. Three Breakthroughs:

    • 35kV Rating: Enables safe insulation for high-voltage transformers, exceeding industry-standard 25kV.
    • 200°C Thermal Stability: Maintains integrity in extreme environments, 50°C higher than traditional PE-only materials.
    • 4:1 Shrink Ratio (Pro Model): 20% faster shrink time than conventional tubes, ensuring precise sealing.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard industrial setups requiring up to 25kV protection.
    • Advanced Model: Perfect for high-voltage applications like power transformers or solar inverters.
    • Pro Model: Designed for extreme environments (e.g., aerospace, offshore drilling) needing 50kV ratings and -60°C to 250°C resilience.

Pro Model’s ceramic-reinforced material triples abrasion resistance compared to industry benchmarks, extending lifespan in harsh industrial settings.
