Material: Fine-stranded bare copper (Class 5 per IEC 60228) for high flexibility.
Structure: Multiple thin wires tightly bundled to allow repeated bending.
Material: PVC (Polyvinyl Chloride).
Function: Provides electrical insulation and mechanical protection.
Material: PVC – Offers abrasion resistance and mild environmental protection.
Design: Smooth or ribbed surface for better handling.
KVVR (Flexible PVC-Insulated PVC-Sheathed Control Cable) is designed for flexible wiring in control circuits, featuring fine-stranded copper conductors (Class 5) and PVC layers. Key uses include:
1.Industrial Control Systems
Connection of movable machinery (e.g., cranes, conveyors, robotic arms).
Control panels and signal transmission in automation equipment.
2.Stage & Entertainment
Temporary power and control wiring for lighting, audio systems, and stage machinery.
3.Building Automation
Flexible links for elevators, HVAC systems, and low-voltage control circuits.
Voltage Rating: 300/500V or 450/750V.
Temperature Range: -15°C to +70°C (short-term up to +90°C).
Bending Radius: ≥6× cable diameter (flexible but not for drag chains).
