High-flexibility unshielded data cable is specially used for data and signal transmission in mobile drag chain systems such as electronic control equipment, machine tools and other mechanical equipment. It is especially suitable for outdoor mobile installation in dry or wet indoor environment in industrial environment. PUR outer sheath makes this cable suitable for extremely harsh industrial environment and occasions with corrosive coolant and lubricating oil. It has excellent oil resistance, abrasion resistance, microbial resistance, hydrolysis resistance, chemical corrosion resistance, UV resistance, and protects the cable from mechanical stress. It can be used in drag chain system and is suitable for frequent bending. When there is external electromagnetic interference, G-HPMCS series products with shielded cables are recommended.
