Structural characteristics
Conductor: multi-strand twisted tinned copper wire, in line with relevant standards, ensuring good conductivity and flexibility.
Insulation: usually polyethylene (PE) or polyvinyl chloride (PVC) insulation material, the insulation layer thickness is uniform, which can effectively prevent short circuits and signal interference between conductors.
Shielding: generally use tinned copper wire precision weaving and aluminum-plastic composite tape wrapping shielding double shielding, which can effectively prevent the influence of external electromagnetic interference on the signal and reduce the signal radiation outward.
Drain wire: Use tinned copper wire fine bundle guide wire as grounding protection to enhance the cable’s anti-interference ability.
Outer sheath: Mostly industrial gray PVC outer sheath, which has the characteristics of wear resistance, weather resistance, corrosion resistance, etc., and can adapt to different use environments. The color of the outer sheath can also be customized according to customer requirements.
Mechanical properties
Minimum bending radius: not more than 6 times the outer diameter of the cable.
Working temperature: usually between – 30℃ and + 80℃.
