Product Introduction
This multi-group double-shielded flame-retardant computer cable (ZC-DJYPVP2 5×3×1.5) is dedicated to precision weak signal transmission for industrial DCS and PLC automation systems, rated at 300/500V. It adopts 5 groups of 3-core twisted differential pairs, low-capacitance XLPE insulation, independent copper braided shielding for each twisted pair, and copper tape wrapped overall total shielding (VP2 structure), matched with Class C flame-retardant PVC outer sheath. The composite double shielding structure provides outstanding suppression of both internal signal crosstalk and external low-frequency electromagnetic interference, making it ideal for factories filled with inverters, large motors and high-power electrical equipment.
product key technologies
1.Solid copper twisted signal pairs (5 groups, 3 twisted pairs per group, single core cross-section 1.5mm²)
2.Low-capacitance XLPE insulation for individual conductors
3.Copper wire braided separate shielding layer for every twisted pair
4.Isolation wrapping tape for each group unit
5.Continuous copper tape wrapped overall total shielding layer (VP2 type)
6.Buffer bedding tape
7.ZC Class C flame-retardant PVC outer protective sheath
- Solid Copper Twisted Pairs：Differential twisted pair layout offsets internal electromagnetic coupling to eliminate crosstalk between multi-channel monitoring signals; high-purity solid copper ensures stable low-resistance transmission of analog/digital sensor signals without signal loss.
- XLPE Core Insulation：Cross-linked polyethylene with ultra-low dielectric constant and stable capacitance avoids waveform distortion and signal attenuation during long-distance transmission; it supports continuous 90°C operation with excellent thermal aging resistance compared to conventional PVC insulation.
- Individual Copper Braided Pair Shield：Every signal pair is wrapped with an independent copper mesh shield to completely isolate interference between different signal loops, guaranteeing measurement accuracy for parallel multi-channel circuits.
- Group Isolation Wrapping Tape：Separates different signal groups to reduce cross-coupling interference between independent control loops inside the cable.
- Copper Tape Wrapped Overall Shield (VP2)：Continuous copper tape wrapping forms a seamless outer shielding barrier, delivering far better shielding efficiency against low-frequency industrial electromagnetic noise (from motors, transformers and inverters) than copper braided total shield types.
- ZC Flame-Retardant PVC Outer Sheath：Class C flame-retardant PVC compound restricts flame spread in case of short-circuit ignition, while resisting indoor moisture, dust and light oil splashes to fully protect the internal shielding and core structure.
Key Advantages

FAQ
Q1: What does ZC-DJYPVP2 stand for?
A: ZC = Class C flame retardant; DJ = computer control cable; YJ = XLPE insulation; P = individual copper braided shield per twisted pair; VP2 = continuous copper tape wrapped overall total shield.
Q2: What is the core difference between VP2 copper tape total shield and ordinary VP copper braided total shield?
A: Copper tape wrapped VP2 structure has 100% seamless coverage, which greatly improves shielding efficiency against low-frequency electromagnetic interference from motors and transformers; copper braided VP shield performs better for high-frequency noise but has gaps in coverage.
Q3: Can this cable only be used for indoor fixed laying?
A: The standard PVC sheath is designed for indoor fixed laying only; customized UV-resistant outer sheath is required for open-air outdoor installation.
Q4: What is the rated voltage of this computer signal cable?
A: Rated voltage 300/500V, exclusively for low-voltage weak signal control circuits, not suitable for heavy-load main power transmission.
Q5: Do you supply low smoke zero halogen versions for public infrastructure projects?
A: Yes, we produce complete WDZ-A/B/C series LSZH double-shield computer cables for subway, hospital and high-rise building projects.
Q6: Why choose DJYPVP2 instead of common RVVP shielded cables for industrial sensors?
A: RVVP uses PVC insulation without twisted pair grouping, causing severe signal crosstalk in multi-channel parallel wiring; DJYPVP2's twisted pair + double shielding structure ensures stable precision analog signal transmission for industrial monitoring systems.
