Product Description
Product Introduction
The bellow is a key component of the passage system, used in high-speed EMUs (Electric Multiple Units) as a flexible connector between two carriages. It reduces air resistance when the train is running at high speeds and prevents rainwater from entering the carriage. At the same time, due to its superior thermal insulation and soundproofing performance, it provides comfort and safety for every passenger on the train.
Product Features
* The passage width is smaller
* Generally without upholstery (roof and side walls)
* The structure is relatively simple
* High requirements for sound insulation, heat insulation and air tightness
* Meet the requirements of aerodynamic load during high-speed meeting
