Product Introduction
This double-shielded flexible computer control cable (ZC-DJYPVPR 2×2×1.5) is a flame-retardant dedicated cable for industrial DCS, PLC and precision sensor weak signal transmission, rated at 300/500V. It adopts multi-strand flexible twisted copper pairs, low-capacitance XLPE insulation, independent copper braided shield for each signal pair + overall full copper braided total shield, and Class C flame-retardant PVC outer sheath. The dual-layer shielding structure greatly suppresses internal signal crosstalk and external electromagnetic interference, perfectly adapting to high-noise industrial workshops with inverters, motors and high-power equipment.
product key technologies
1.Stranded flexible copper twisted signal pairs (2 groups, 2 cores per group, cross-section 1.5mm² each core)
2.Low-capacitance XLPE insulation for single conductor
3.Separate copper wire braided shielding layer for each twisted pair
4.Isolation wrapping tape for each pair unit
5.Dense copper braided overall total shielding layer
6.Flame-retardant buffer bedding tape
7.ZC Class C flame-retardant PVC outer protective sheath
- Flexible Stranded Twisted Copper Pairs:Multi-strand soft copper delivers stable low-resistance differential signal transmission. The twisted pair layout offsets internal electromagnetic crosstalk, and flexible structure fits repeated minor bending inside electrical cabinets and movable testing instruments.
- XLPE Core Insulation Layer:Cross-linked polyethylene features ultra-low dielectric constant and stable capacitance, eliminating signal attenuation and phase shift during long-distance transmission; it withstands continuous 90°C operating temperature with superior anti-aging performance compared to ordinary PVC insulation.
- Independent Pair Copper Braided Shield:Every signal pair is wrapped with an individual copper mesh shield, completely isolating interference between different signal loops and avoiding data distortion caused by multi-channel parallel wiring.
- Full Copper Overall Total Shield:The secondary outer copper braided shield forms a double anti-interference barrier, fully blocking external EMI/RFI noise generated by heavy industrial equipment such as frequency converters and high-voltage cabinets.
- ZC Flame-Retardant PVC Outer Sheath:Class C flame-retardant compound restricts flame spread when short-circuit ignition occurs, while resisting indoor moisture, dust and light oil splashes to fully protect internal shielding and core structure.
Key Advantages
- Dual-Layer Full Shielding Design: Independent pair shield + overall total shield provides top-grade anti-interference performance for harsh high-electromagnetic-noise industrial environments.
- Flexible Conductor Layout: Multi-strand soft copper supports frequent small-angle bending, suitable for cabinet wiring and slightly movable precision instrument connection.
- Class C Flame Retardant Safety Performance: Meets industrial fire protection standards, effectively inhibiting flame propagation to reduce hidden fire hazards in workshops.
- Low-Capacitance XLPE Insulation: Guarantees high-fidelity analog/digital signal transmission without waveform distortion over long distances.
- Anti-Crosstalk Twisted Pair Structure: Differential twisting eliminates mutual interference between multi-channel monitoring signals, improving measurement accuracy of flow, temperature and pressure transmitters.
- International Standard Compliance: Produced strictly in accordance with GB/T 9330 and corresponding IEC standards for flame-retardant computer control cables.

FAQ
Q1: What does ZC-DJYPVPR stand for?
A: ZC = Class C flame retardant; DJ = computer control cable; YJ = XLPE insulation; P = independent shield for each twisted pair; VP = overall total copper shield; R = stranded flexible conductor.
Q2: What is the core difference between DJYPVPR double-shield cable and single-shield DJYVP cable?
A: DJYPVPR adds separate shielding for every single signal pair, which thoroughly eliminates signal crosstalk between different loops, making it ideal for multi-channel parallel precision analog signal transmission in strong interference sites; DJYVP only has an overall outer shield, only suitable for simple single-loop control circuits.
Q3: Can this cable be used for slightly movable instrument wiring?
A: Yes, the R-type multi-strand flexible copper conductor can withstand repeated minor bending inside control cabinets and portable testing equipment.
Q4: Is this cable applicable to fire-risk industrial workshops?
A: Its ZC Class C flame-retardant outer sheath can limit flame spread, meeting basic fire protection requirements for general industrial production workshops.
Q5: What is the rated voltage of this computer signal cable?
A: Rated voltage 300/500V, specially designed for low-voltage weak signal control circuits, not applicable for heavy-load main power transmission.
Q6: Can you supply low smoke zero halogen flame-retardant DJYPVPR cables for public buildings?
A: Yes, we produce complete WDZ-A/B/C series low smoke zero halogen double-shield computer cables for subway, hospital, school and high-rise building projects.
