KVV: PVC/PVC Control Cable

R: Think of power cables as the muscle and KVV as the brain. Power cables carry heavy electricity, while KVV handles control signals. KVV usually operates at lower voltages (450/750V) but contains many more cores—sometimes up to 61—to manage complex commands.

 A: Standard KVV is best suited for indoor installation in conduits or trenches. It isn’t built for direct burial because it lacks steel armor protection. If you need to bury it, we suggest upgrading to KVV22 (Steel Tape Armored). For outdoor use exposed to sun, we can add UV resistance to the outer sheath upon request.

A: For cables with a small number of cores (usually under 5), we use different colors. For cables with many cores (like 10, 20, or more), we use white numbering on black insulation. This makes it much faster for your electricians to trace connections during installation.

A: It depends on your preference. We offer both Class 1 (Solid copper) and Class 2 (Stranded copper). Most clients prefer the stranded Class 2 version because it is easier to bend and route through tight cable trays compared to the stiff solid version.

A: The standard PVC used in KVV is rated for 70°C. However, if your environment is hotter, we can switch the insulation material to handle 90°C or even 105°C. Just let us know the operating conditions before we quote.

A: The base model is standard PVC. But we frequently manufacture it as ZR-KVV (Flame Retardant). This means if a fire occurs, the cable will self-extinguish after the flame source is removed, which is a safety requirement in many industrial buildings.

R: Yes. While black is the industry standard for control cables, we can extrude the outer sheath in grey, red, or other colors if you need to distinguish between different systems (like fire alarms vs. regular control) visually.
