Scope of Application
Primarily suitable for power lines in fire alarm and fire protection equipment, communication equipment, and emergency exit transportation systems that require fire resistance at rated voltages of 600/1000V and below. Particularly applicable to power transmission systems outside the containment of nuclear power plants under seismic loads, ensuring emergency shutdown, containment isolation, core emergency cooling, reactor heat removal, and prevention of radioactive material release into the surrounding environment.
