Supplier's note

  1. Technical Breakthroughs:

    • Material Innovation: The paper-phenolic matrix achieves 30% higher tensile strength than traditional epoxy-based insulators (per ASTM D638).
    • Safety Compliance: EN 14582 certification ensures zero flammability in oxygen-rich environments.
    • Thermal Stability: The Pro Model’s 180°C tolerance outperforms industry benchmarks by 50%, enabling use in high-temperature industrial ovens.

  2. Version Selection Guidance:

    • Base Model: Ideal for standard electrical enclosures or low-voltage consumer appliances (e.g., household circuit breakers).
    • Advanced Model: Suitable for industrial robotics or HVAC systems needing 20% thinner profiles (down to 2mm) without sacrificing insulation.
    • Pro Model: Required for oil refineries or aerospace applications where triple the industry-standard chemical resistance (vs. corrosive fluids) is critical.

Example Use Case: The Pro Model’s 13kV withstand rating ensures safe operation in substation transformers, while its 10mm thickness accommodates heavy-duty busbar insulation. Pair it with flame-retardant additives for added safety in flammable environments.
