Supplier's note

  1. Three Technical Breakthroughs:

    • Material Blend: The phenolic-bakelite-paper composite achieves 20% higher dielectric strength than traditional fiberglass tubes.
    • Voltage Handling: The 11kV baseline rating (Base Model) scales up to 20kV (Pro) to meet extreme power grid demands.
    • Marine Corrosion Shield: The glossy finish reduces saltwater corrosion by 40% compared to uncoated metal tubes.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard marine applications (e.g., ship shaft bushings) where 11kV insulation suffices.
    • Advanced Model: Suitable for offshore oil rigs or heavy machinery requiring 15kV protection and heat resistance up to 180°C.
    • Pro Model: Designed for high-voltage substations or chemical plants needing 20kV ratings and resistance to aggressive chemicals.

With phenolic resin’s inherent flame retardancy, you can ensure compliance with marine safety standards. The Pro Model’s 20kV rating, paired with 220°C thermal tolerance, enables safe operation in extreme industrial environments.
