Product Introduction
Product Introduction
KVVP is a copper conductor, PVC insulated, PVC sheathed, copper braided shield control cable designed for reliable signal transmission in AC rated voltage 450/750V control and monitoring circuits. Internationally equivalent toLiYCY, NYCY, and CY control cables, it provides exceptional electromagnetic interference (EMI) and radio frequency interference (RFI) protection critical for precision automation systems. This cable ensures stable operation in harsh industrial environments where signal integrity directly impacts operational safety and efficiency.
product key technologies
Product Construction
- Conductor: Made of stranded copper wires with a cross-section of 0.5–25mm² and multiple strands. Its core function is to transmit control signals with low resistance, while the stranded structure ensures high flexibility, making it easy to install and connect to various control equipment (such as PLCs, sensors, and actuators) without breaking or damaging the conductor.
- Insulation Layer: Adopts PVC (Polyvinyl Chloride) material that complies with GB/T 9330-2020 standard. It is closely wrapped around each conductor to achieve electrical isolation between different conductors, preventing voltage breakdown and protecting the conductor from environmental factors (such as moisture and dust), thus avoiding short circuits and ensuring the safety of signal transmission.
- Filler & Binder : Composed of flame-retardant PP rope and polyester film. The filler tightly fills the gaps between conductors to maintain the roundness of the cable, preventing core displacement during installation or use; the polyester film wraps the core to enhance the overall structural stability of the cable, avoiding loose conductors and affecting signal transmission.
- Shielding Layer : Made of tinned copper braid with a coverage rate of ≥80–85% and an interference attenuation of ≥30dB. This is the core structure for anti-interference: it can effectively block external EMI and RFI (such as interference from nearby power cables, motors, and variable frequency drives), reduce signal crosstalk between conductors, and ensure the integrity and accuracy of control signals, which is crucial for precision control systems.
- Outer Sheath : Uses flame-retardant PVC material with a thickness of ≥1.2mm (for cables with 10 cores or less). It acts as the outermost protective layer, providing mechanical protection against impact, abrasion, and extrusion during transportation and installation; at the same time, it has good resistance to oil, chemicals, and moisture, extending the service life of the cable in harsh industrial environments.
Core Product Advantages
- Superior EMI/RFI Suppression： Copper braid shielding provides 30dB+ interference attenuation, significantly reducing signal errors compared to unshielded cables, making it ideal for high-noise industrial environments with VFDs and heavy machinery.
- Optimized Mechanical Performance ：Stranded copper conductors ensureflexibility for tight bends and easy termination; robust PVC sheath offers excellent mechanical protection against impact and abrasion; tinned copper shielding resists oxidation, extending service life.
- Cost-Effective Reliability： Balances performance and affordability for industrial applications; reduces installation time with flexible design and easy handling; minimizes maintenance costs by lowering system failure rates.
- Broad Compatibility & Compliance： Internationally recognized equivalent to LiYCY/NYCY/CY control cables; compliant with GB/T 9330-2020, CE, RoHS, and ISO 9001 standards; rated for -15°C to +70°C operating temperature range; available in 2–37 core configurations to meet diverse control needs.
- Customization Capability： Flexible core count (2–37) and cross-section (0.5–25mm²) options; flame-retardant, low-smoke zero-halogen (LSZH), and armored variants available; custom lengths and packaging to suit project requirements.

FAQ
Q1: What is the difference between KVVP and LiYCY/NYCY/CY control cables?
A1: KVVP is internationally equivalent to LiYCY, NYCY, and CY cables. They share the same core structure (copper conductor, PVC insulation, copper braid shielding, PVC sheath) and functional purpose for control signal transmission. The only minor difference lies in regional standard naming conventions, with KVVP complying with GB/T 9330-2020, while LiYCY/NYCY/CY follow European standards.
Q2: Can KVVP cables be used for outdoor installation?
A2: Yes, KVVP cables can be used for outdoor fixed installation (such as in cable trays or conduits) thanks to their flame-retardant, moisture-resistant PVC outer sheath. However, they are not suitable for direct burial in soil; for underground installation, we recommend choosing armored KVVP variants (customizable).
Q3: What customization options are available for KVVP cables?
A3: We offer flexible customization, including core count (2–37 cores), conductor cross-section (0.5–25mm²), sheath material (flame-retardant PVC, LSZH), shielding coverage (up to 90%), and custom lengths/packaging. Armored variants are also available for enhanced mechanical protection.
Q4: Are KVVP cables compliant with international standards for export?
A4: Yes, all KVVP cables comply with GB/T 9330-2020, CE, RoHS, and ISO 9001 standards, which meet the import requirements of most countries and regions (including the EU, North America, and Southeast Asia). We can provide relevant certification documents upon request.
Q5: What is the operating temperature range of KVVP cables?
A5: The standard operating temperature range of KVVP cables is -15°C to +70°C. For extreme temperature environments (below -15°C or above +70°C), we can provide customized low-temperature or high-temperature resistant variants.
Q6: How to choose the right core count and cross-section for my application?
A6: The core count depends on the number of control signals you need to transmit (e.g., 2–4 cores for simple motor control, 10–37 cores for PLC/DCS systems). The cross-section is determined by the current and transmission distance: 0.5–1mm² for short-distance (≤50m) low-current signals, 1.5–25mm² for long-distance or high-current applications.
