Supplier's note

  1. Technical Breakthroughs:

    • Material Blend: Paper-wood pulp composites reduce cost by 20% vs. solid fiberglass, without sacrificing dielectric strength.
    • Voltage Tolerance: The Pro Model’s 110kV rating exceeds industry benchmarks (typically 80kV), enabling use in ultra-high-voltage substations.
    • Color-Coded Safety: Red variants comply with ANSI Z535 standards, enhancing hazard identification in industrial settings.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard industrial applications (e.g., low-to-medium voltage transformers).
    • Advanced Model: Recommended for heavy-duty machinery (e.g., electric vehicle charging stations) requiring 60kV resilience.
    • Pro Model: Designed for critical infrastructure (e.g., power grids) where extreme voltage and mechanical stress are routine. With its triple-certification (IEC 62278), it ensures compliance with global safety protocols.

*Pro Model’s voltage rating is 214% higher than the Base Model.
