Regarding our Shielded Cables:
- The 4 core and 2 core shielded cables by Bulk-Man 3D are cut in the proper length for customers convenience which meet the needs and multifunction of different size of our CNC Machine.
- This high quality 4 core cable has 2 layers of insulation and 2 shield layers to reduce signal interference and maximise efficiency.
- The four insulated wires are shielded by oxygen free tinned annealed copper wire braid with Aluminium/PET tape (100% coverage) to shield the cores from EMF interference.
- This is again insulated by a thick clear layer of thermoplastic sheath insulation. Suitable for applications requiring electrical/electronic screening of cable. 22AWG suitable for 300V DC and up to 80°C
