WTB (Wire Train Bus) Cable - The Core Component for Building Reliable Train Communication Networks (TCN)
Our WTB (Wire Train Bus) cable is a core solution engineered to deliver stable communication between critical equipment within modern rail transit vehicles. Serving as the foundational element for constructing international standard-compliant Train Communication Networks (TCN) , it provides highly reliable, real-time data transmission channels for locomotives, EMUs, and other rolling stock. This infrastructure is essential for enabling intelligent train control, safe operation, and efficient maintenance .
