Abstract: Rail transit is an important component of urban transportation, and train wire harnesses serve as the neural network ensuring normal operation of all systems.

High-speed rail and subway cars are filled with various wire harnesses, including traction systems, braking systems, passenger information systems, etc. Rail transit has extremely strict fire protection requirements for wire harness materials, must comply with international standards such as EN45545 and DIN5510.

Halogen-free fiberglass sleeving meets the strict fire safety standards of rail transit, does not release toxic halogen gases at high temperatures, has low smoke density, and provides important assurance for passenger safety.

YC INSULATION's products have been applied in multiple domestic subway lines and high-speed rail projects, receiving wide recognition from customers.
