Structural characteristics
Conductor: 4 pairs of 8 cores (4x2x16AWG) stranded tinned copper wire, in line with VDE0295 Class 5 standards, ensuring good conductivity and flexibility.
Insulation: Polyethylene (PE) insulation material is usually used, and the insulation layer thickness is uniform, which can effectively prevent short circuits and signal interference between conductors.
Shielding: Generally, double shielding with aluminum foil/polyester composite tape shielding rate + tinned copper braided mesh with 90% shielding rate is used, which can effectively prevent the influence of external electromagnetic interference on the signal and reduce the outward radiation of the signal.
Drain wire: 16AWG multi-strand twisted tinned copper wire is used as grounding protection to enhance the anti-interference ability of the cable.
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: Generally 6 times the cable diameter during installation.
Working temperature: Usually between – 30℃～+70℃.
Tensile strength: Meet certain tensile requirements to ensure that the cable will not break easily during normal use and installation.
Compression resistance: Can withstand certain pressure, such as ground pressure or extrusion of other objects during laying.
Others
Compliance with standards: Comply with UL AWM 2919 and other relevant standards.
Application scenarios: Applicable to industrial automation control network communication, building automation network communication, intelligent transportation system, power automation and other fields, which can realize stable and reliable data transmission between devices
