TRVV, TRVVP and PUR drag chain cables comply with the GB/T5023, GB/T9330 and CE, UL industry standards; PUR cables are oil-resistant and abrasion-resistant. Standard TRVV serves as power wiring in drag chains; shielded TRVVP resists electromagnetic interference and transmits sensor and servo control signals; highly flexible PUR drag chain cables withstand repeated bending as well as acids and alkalis. They are widely used for reciprocating wiring in CNC machine tools, industrial robotic arms, automated assembly lines and warehouse stacker cranes, suiting demanding industrial conditions with frequent flexing, oil and dust.
