KVVR Control Cable (PVC Insulated Flexible Control Cable)
KVVR control cable is a copper conductor, PVC insulated and PVC sheathed flexible control cable, developed based on the KVV control cable. The main difference is that KVVR uses fine-stranded flexible copper conductors, making it more suitable for applications requiring frequent bending or movement.
Construction
- Conductor: Fine-stranded annealed copper (flexible class conductor)
- Insulation: PVC (Polyvinyl Chloride)
- Cabling: Multi-core twisted construction
- Sheath: PVC outer jacket (commonly black)
Key Features
- Excellent flexibility and bending performance
- Better suited for dynamic or semi-moving installations compared to KVV
- Good mechanical strength and durability
- Cost-effective general-purpose control cable
- Suitable for both fixed and light mobile applications
Electrical Ratings
- Rated voltage: 450/750V
- Operating temperature: up to 70°C (long-term)
- Installation temperature: ≥ 0°C
- Bending radius: smaller than KVV due to flexible structure
Applications
- Industrial automation control systems
- Machine tools and equipment wiring
- Control cabinets and switchgear connections
- Light-duty mobile equipment
- Building electrical control circuits
Difference Between KVV and KVVR
- KVV: Solid or semi-rigid copper conductor – standard flexibility – fixed installation
- KVVR: Fine-stranded flexible copper conductor – high flexibility – light movement applications
