Transportation & Tunnel
Extreme High-Temperature Tolerance:
Through specially designed insulation materials, high-temperature resistant windings, and reinforced cooling structures, can withstand instantaneous extreme high temperatures of 150°C to over 400°C during fires and operate stably for 90-180 minutes under such harsh conditions. Effectively resists erosion from dust, smoke, and toxic gases accompanying tunnel fires, preventing corrosion, blockage, or functional failure of motor components, ensuring core performance stability in complex fire environments.
Reliable Emergency Operation:
As critical emergency equipment, possesses instant start capability. Can operate continuously and stably even under grid fluctuations or extreme conditions, providing uninterrupted power for tunnel smoke extraction systems, ensuring the safety of personnel evacuation routes
