WTB data cable USAGE SCOPE
WTB data cable is based on the fireproof performance requirements of the rail transit industry. Under the fire, the smoke is very small when the cable burns, and the smoke is not toxic and corrosive and does not cause secondary combustion. The cable has good EMC characteristics and is used for multifunctional data transmission in vehicles.
