ZR-KVVRP cable is a flexible flame-retardant control cable with PVC insulation, PVC sheath, and a braided copper wire shield for enhanced protection against electromagnetic interference (EMI). This cable is specially designed for signal control circuits that require both flexibility and shielding performance, while meeting fire safety standards (ZR = flame retardant).
It is ideal for industrial automation, instrumentation, and electrical control systems where stable signal transmission and fire protection are required.
🔧 Key Features
Flame-retardant PVC insulation and sheath, compliant with IEC 60332
Stranded copper conductors (Class 5) for excellent flexibility
Dense copper braid shielding (coverage ≥85%) for reliable EMI protection
Voltage rating up to 450/750V, suitable for most control and signal systems
Available in multi-core designs (up to 61 cores)
Excellent electrical performance, mechanical strength, and fire resistance
