Simple structure
Meet the requirements of sound insulation, heat insulation and air tightness for high speed trains
Introduction
Folding bellow is a key component of gangway system, it is applied on the high speed bullet trains, as a flexible connection that links two carriages, it will reduce air resistance while the train moves at rapid speed, keep the rainwater from entering inside the train. Meanwhile, thanks to its better heat insulation and sound proofing, it brings a feeling of comfort and safety to every passenger on the train.
