KVVP Shielded Control Cable for Precision Instrumentation & EMI Protection 450/750V PVC Insulated Copper Braid

High-interference industrial environments (e.g., near frequency converters, inverters, and high-voltage equipment) often lead to control signal distortion, resulting in PLC malfunctions, precision equipment errors, and costly production downtime. KVVP shielded control cables, with their specialized anti-interference design and robust materials, are designed to address these pain points. Featuring high-purity Category 2 stranded copper conductors, precision PVC insulation, a 90% coverage copper wire braided shield, and a reinforced PVC outer sheath, they block 99% of EMI/RFI interference, ensuring stable low-voltage signal transmission. They are resistant to industrial oils and abrasion and operate stably in temperatures ranging from -30°C to 70°C. This product has passed EU (CE/RoHS 3.0), North American (UL 1277), Australian (SAA), and Middle East & North Africa (SASO) standard certifications, making it a trusted choice for high-precision manufacturing plants, PLC system integrators, and industrial control engineers worldwide.

KVVP is a high-performance, low-voltage (0.45/0.75kV) shielded control cable specifically designed for signal transmission and control command delivery in high-interference industrial environments. It is used to connect PLCs, sensors, actuators, and control panels near frequency converters, inverters, or high-voltage lines. Its interference-optimized structure ensures signal integrity: Category 2 stranded copper conductors (low resistance, stable signal), precision PVC insulation (excellent dielectric strength, low signal attenuation), a 90% coverage copper braided shield (core interference-resistant layer, grounded to eliminate EMI/RFI), and a reinforced PVC outer sheath (protective layer, oil-resistant, abrasion-resistant, and UV-resistant).

"KVVP" definition: K = Control cable (specifically for industrial control scenarios); V = PVC (polyvinyl chloride) insulation; V = PVC outer sheath; P = Copper braided shield (over 90% coverage). Its unique feature lies in the fact that, unlike unshielded KVV/KVVR control cables, KVVP adds a high-coverage copper braided shielding layer, solving the core pain point of signal distortion in high-interference environments. It is specifically designed for precision control systems located near interference sources, rather than general low-interference applications—this distinguishes it from all unshielded control cables with unique anti-interference capabilities.

• 90% Copper Braided Shielding for Interference Reduction: 90% copper braided shielding complies with IEC 61000-4-6 and UL 1277 interference reduction standards, providing ≥85dB shielding effectiveness in the 100MHz~1GHz frequency range. It blocks 99% of EMI/RFI interference from frequency converters, inverters, and high-voltage equipment, eliminating signal distortion in control systems. In high-interference workshops, it can reduce equipment failure rates by 55%—crucial for PLC-based precision automation.
• Stable Signal Transmission for Precise Control: Utilizing uniform cross-section Class 2 stranded copper conductors and precision PVC insulation, it minimizes signal attenuation (≤1.3% attenuation over 100m length with a 1.5mm² cross-section) and capacitance (≤170pF/m). This ensures accurate transmission of control commands between the PLC and field devices, improving automation accuracy by 40%, making it ideal for pharmaceutical filling lines, electronic component installation, and other high-precision process control.
• Industrial-grade oil and abrasion resistance: The reinforced PVC outer sheath is fortified with oil-resistant and abrasion-resistant additives, making it resistant to industrial oils (mineral oils, lubricants), greases, and mechanical friction. It has passed 12,000 cycles of abrasion testing, maintaining sheath integrity even in high-friction environments (cable trays, control cabinet gaps, machine tool wiring). There is no sheath cracking or shielding damage, ensuring a service life of over 12 years even in harsh industrial environments.
• Globally adaptable to all climates (-30°C to 70°C): The PVC sheath is formulated with antifreeze, UV resistance, and salt spray resistance. It operates reliably in extremely cold industrial control rooms (-30°C), high-temperature workshop control systems (70°C), desert manufacturing plants (60°C), and coastal industrial facilities. It is moisture-resistant, dust-proof, and resistant to weak acids/alkalis, requiring no additional protective housing in most high-interference industrial scenarios worldwide.
• Global high-precision control certifications and compliance: CE/RoHS 3.0 (EU, compliant with EN 50200 and IEC 60228 standards), UL 1277 (North America, compliant with NFPA 70 NEC standards), SAA (Australia/New Zealand), SASO (Middle East and North Africa) certifications. Customized compliance documentation (e.g., immunity test reports, PLC system compatibility certificates) can be provided for high-precision control projects to ensure smooth project approval. Popular specifications are in stock (3-day fast shipping), and emergency high-precision automation upgrades are supported.

Note: All specifications are in stock (fast shipping within 3 days). Bulk orders can customize the number of cores (up to 37 cores) and cross-section (0.75~6mm²), ensuring comprehensive immunity, signal stability, and regional certification. Color-coded cores (compliant with IEC/UL standards) and shielded grounding terminals facilitate wiring and interference elimination.

What are the differences between KVVP, KVV, and KVVR cables?

KVVP uses a 90% copper braided shield (anti-electromagnetic interference, suitable for high-interference scenarios); KVV is an unshielded cable (suitable for fixed low-interference wiring); KVVR is an unshielded flexible cable (suitable for mobile low-interference scenarios). If your control system is close to frequency converters, inverters, or high-voltage lines, please choose KVVP to avoid signal distortion.

How to ensure the KVVP shielding layer provides optimal anti-interference performance?

We recommend single-point grounding (grounding resistance ≤4Ω) at the PLC/inverter end using the matching grounding terminal. Avoid multiple grounding points (as this can create grounding loops and reduce shielding effectiveness). Detailed shielding and grounding guidelines are provided free of charge with all orders, and on-site guidance is available for large-volume projects.

Can KVVP be used in outdoor control systems in high-interference environments?

Yes. Its UV-resistant and moisture-proof PVC sheath is suitable for outdoor high-interference scenarios (e.g., outdoor inverter control panels, outdoor PLC wiring). For long-term outdoor use in areas with heavy rain or high humidity, we recommend the KVVP-OW version, designed specifically for outdoor environments, which features an enhanced waterproof sheath and UV-resistant additives.

Is KVVP compatible with all major PLC brands?

Absolutely compatible. It is fully compatible with top global PLC brands, including Siemens, Rockwell Automation, Mitsubishi, Omron, Schneider Electric, and Rockwell Automation. Stable signal transmission and anti-interference performance ensure seamless communication between the PLC and field devices. We provide PLC system compatibility test reports for bulk orders.

What is the minimum order quantity for custom KVVP cores?

The minimum order quantity for custom core quantities (e.g., 18 cores, 24 cores) is 600 meters per specification. For urgent small-batch custom orders (300~600 meters) for high-precision control system maintenance, we offer priority production service, guaranteeing delivery within 10 working days for a small surcharge.

Can KVVP withstand temperatures above 70°C?

Standard KVVP can operate continuously at 70°C. For high-temperature, high-interference scenarios (70°C~90°C, such as VFD proximity control in high-temperature workshops), we offer the KVVP-H high-temperature version made of heat-resistant PVC material, maintaining anti-interference performance and signal stability at 90°C and conforming to the same global standards.
