PVC Insulated Control Cable (KVV Cable) – 450/750V GB/T 9330
Farwalk’s PVC Insulated Control Cables are the foundational nervous system of industrial automation. Designed with high-density multi-core configurations, they provide flawless transmission of critical commands and sensory data between control panels, machinery, and automated production lines.
Manufactured to GB/T 9330 and IEC 60227 standards. The conductors are plain annealed copper (Class 1 solid or Class 2 stranded). The cores are insulated with premium PVC, clearly identifiable via numerical printing (Number Coded) or distinct color coding. The cores are stranded together in concentric layers and protected by a durable, oil-resistant PVC outer sheath.
Universally deployed in manufacturing plants, power station control rooms, conveyor systems, and CNC machinery setups. Because they are unarmoured and utilize a soft PVC jacket, they offer excellent bending flexibility, making them the standard choice for routing through indoor cable trays, wall trunking, and tight control cabinets where severe mechanical impact is not a primary threat.
• Voltage Rating: 450/750V (or 0.6/1kV)
• Conductor: Pure Copper (Solid or Stranded)
• Core Count: 2 Cores up to 61 Cores
• Cross Section: 0.5 mm² to 10 mm²
• Standards: GB/T 9330 (KVV), IEC 60227
1. Conductor: Plain annealed copper wires, Solid (Class 1) or Stranded (Class 2).
2. Insulation: High-grade PVC (Polyvinyl Chloride) rated for 70°C.
3. Core Identification: Cores are precisely identified by clear numerical printing on a black background, or by distinct color coding (often including a Green/Yellow earth core).
4. Assembly: Cores are twisted together in concentric layers with optimal lay lengths to ensure cable flexibility and roundness.
5. Outer Sheath: Extruded PVC jacket, resistant to industrial oils and mechanical abrasion.
• Precision Signal Transmission: Engineered specifically to carry critical low-voltage control signals, commands, and measurements across industrial environments without data loss.
• High Core Density: Available in massive configurations ranging from 2 cores all the way up to 61 cores, allowing the consolidation of complex sensory arrays into a single manageable cable.
• Excellent Bending Radius: Because it is unarmoured and relies on flexible PVC, the cable is easily routed through tight corners in control panels and indoor cable trays.
• Perfect Core Identification: Our advanced printing lines guarantee that even in a 61-core cable, every single white number is crisp, legible, and highly resistant to fading during installation.
• Material Versatility: We offer exact matches for both the Chinese KVV standard and the European IEC 60227 specs, ensuring your project passes local engineering inspections.
• Custom Extrusion: Need a specific 37-core layout with a custom sheath color or specialized oil-resistant PVC compound? We provide rapid custom runs for specialized industrial requirements.
Comparison Logic
| Feature | PVC Control (KVV) | Screened PVC (KVVP) | Armoured PVC (KVV22) |
| Flexibility | Excellent (Easiest to bend) | Good (Slightly stiffer due to copper braid) | Very Stiff (Heavy steel tape protection) |
| EMI Protection | Low (No metallic shield) | Excellent (Blocks electromagnetic interference) | Moderate (Steel tape provides some shielding) |
| Mechanical Defense | Low (Relies on cable trays/conduits) | Low | Ultimate (Direct burial, crush proof) |
| Primary Use | Standard indoor control panels | VFDs, sensitive signal routing | Harsh environments, underground |
