Nuclear Power Plant Motors: Absolute Safety Standards

1. Solution Overview

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 and Inside the Boiling Water Reactor (BWR) Containment. These products meet the most stringent global standards for material durability and nuclear safety.

2. Technical Features & Specialized Materials

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:

• Superior Insulation Systems: Utilizing Class B and Class H insulation materials, allowing the motor to withstand continuous high operating temperatures without performance loss.

• Radiation Resistance: Motors designated for use inside the BWR containment are equipped with Special Class H insulation, engineered to resist material degradation caused by long-term radiation exposure.

• High-Heat Lead Wires: All leads utilize 600V LKGB type wiring. For units inside the containment, wires are further protected by glass tubing to enhance thermal resistance and dielectric strength.

• Sealing & Oil Seals: Premium Viton and Silicon materials are used to maintain airtightness and elasticity even in the presence of chemicals and intense radiation.

• Specialized Bearing Grease: Utilizing Castrol Nucleol G130 and DuPont synthetic heat-resistant lubricants, ensuring bearings run smoothly without drying out or chemically altering throughout the maintenance cycle.
