AI Technical Summary
Traditional monitoring signal transmission cables have insufficient shielding effectiveness, poor insulation and weather resistance, and weak resistance to mechanical friction damage, making them difficult to use for a long time under complex working conditions.
It adopts a multi-layer composite structure design, including a conductor core wire, a composite shielding layer, a double insulation layer and an outer sheath from the inside out. The composite shielding layer is composed of a tightly bonded metal braided layer and a conductive aluminum foam layer. The insulation layer adopts a double-layer co-extrusion structure. The outer sheath has annular protrusions. The wave-absorbing layer is a silicone rubber layer doped with carbon nanotubes.
It significantly improves shielding effectiveness, enhances weather resistance and resistance to mechanical damage, extends the service life of the cable, and ensures the stability and accuracy of signal transmission.
