Product Introduction
This twisted-pair total shielded computer cable (DJYVP 2×3×1.5mm²) is specially engineered for precise weak signal transmission in industrial distributed control systems (DCS/PLC). Rated at 300/500V, it adopts twisted-pair core layout, XLPE insulation, full copper braided overall shielding and PVC outer sheath. The multi-group paired structure eliminates crosstalk between signal lines, and double-layer shielding blocks external electromagnetic interference, ensuring distortion-free transmission of low-level analog/digital signals in high-interference factory environments.

- Twisted Pair Copper ConductorsDifferential twisted pair design suppresses internal crosstalk between adjacent signal lines; high-purity solid copper delivers stable low-resistance transmission for weak sensor signals. Independent grouping separates different signal loops to avoid mutual interference.
- XLPE Core InsulationCross-linked polyethylene features ultra-low dielectric constant and stable capacitance, guaranteeing consistent signal impedance without waveform distortion during long-distance transmission. It supports 90°C continuous operating temperature with superior heat aging resistance compared to PVC insulation.
- Group Isolation Wrapping TapeSeparates different signal groups to reduce cross-coupling interference between multi-channel control circuits.
- Copper Braided Total Shielding LayerDense copper mesh fully encloses all core groups, blocking external EMI/RFI interference generated by motors, inverters and high-power equipment, which is the core guarantee for stable precision signal output.
- PVC Outer SheathDurable PVC compound protects internal shielding and cores from moisture, dust, minor abrasion and chemical corrosion in indoor industrial workshops.

FAQ
Q1: What does DJYVP stand for?
A: DJ = computer control cable; YJ = XLPE insulation; V = PVC outer sheath; P = overall copper braided shielding.
Q2: What is the core advantage of twisted pair layout compared to ordinary multi-core cables?
A: Twisted differential pairs offset electromagnetic interference inside the cable, effectively eliminating signal crosstalk between different monitoring channels.
Q3: What is the difference between DJYVP and ordinary RVVP shielded cables?
A: DJYVP uses low-capacitance XLPE insulation and standardized twisted pair grouping for weak precision signals; RVVP uses PVC insulation, mainly for general control power circuits, not suitable for long-distance analog sensor transmission.
Q4: Can this cable be laid outdoors exposed to sunlight?
A: Standard PVC sheath is only for indoor use; customized UV-resistant LSZH outer sheath version is required for outdoor open-air laying.
Q5: What is the rated voltage of this computer cable?
A: Rated voltage 300/500V, exclusively for low-weak signal control circuits, not for heavy-load main power transmission.
Q6: Do you supply flame-retardant low-smoke zero-halogen DJYVP cables?
A: Yes, WDZ-A/B/C series LSZH computer shielded cables are available for subway, hospital and high-rise public building projects.
