Nuclear Power Plant Motors: Absolute Safety Standards<\/strong><\/h1>\n

1. Solution Overview<\/strong><\/h2>\n

In the unique environment of a nuclear power plant, drive systems must face extreme challenges involving high temperatures and ionizing radiation. Our motor series is specifically engineered for stable operation in two critical zones: Outside the Containment Vessel<\/b> and Inside the Boiling Water Reactor (BWR) Containment<\/b>. These products meet the most stringent global standards for material durability and nuclear safety.<\/p>\n

2. Technical Features & Specialized Materials<\/strong><\/h2>\n

The distinction of this motor series lies in the rigorous selection of materials for every component, ensuring they do not degrade under radiation or high thermal stress:<\/p>\n

    \n
  • \n

    Superior Insulation Systems:<\/b> Utilizing Class B and Class H<\/b> insulation materials, allowing the motor to withstand continuous high operating temperatures without performance loss.<\/p>\n<\/li>\n

  • \n

    Radiation Resistance:<\/b> Motors designated for use inside the BWR containment are equipped with Special Class H insulation<\/b>, engineered to resist material degradation caused by long-term radiation exposure.<\/p>\n<\/li>\n

  • \n

    High-Heat Lead Wires:<\/b> All leads utilize 600V LKGB<\/b> type wiring. For units inside the containment, wires are further protected by glass tubing<\/b> to enhance thermal resistance and dielectric strength.<\/p>\n<\/li>\n

  • \n

    Sealing & Oil Seals:<\/b> Premium Viton and Silicon<\/b> materials are used to maintain airtightness and elasticity even in the presence of chemicals and intense radiation.<\/p>\n<\/li>\n

  • \n

    Specialized Bearing Grease:<\/b> Utilizing Castrol Nucleol G130<\/b> and DuPont synthetic heat-resistant lubricants<\/b>, ensuring bearings run smoothly without drying out or chemically altering throughout the maintenance cycle.<\/p>\n<\/li>\n<\/ul>\n
