KVVR cable is a flexible control cable with PVC insulation and PVC outer sheath, designed for signal transmission, control, and protection circuits in fixed indoor installations or occasional flexible applications. It is widely used in power stations, automation systems, electrical equipment, and instrumentation.
Thanks to its stranded copper conductors, KVVR cable offers greater flexibility than traditional solid-core control cables, making it easier to install in tight spaces and complex routing systems.
🔧 Key Features
Flexible stranded copper conductors for easy installation and routing
PVC insulation and sheathing for good flame resistance, insulation performance, and chemical resistance
Suitable for 450/750V and 0.6/1kV applications
Manufactured according to GB/T 9330, IEC 60227, and IEC 60502 standards
Multi-core construction (2–61 cores available) for control system flexibility
Low capacitance and stable signal transmission
