KVV - Copper core PVC insulated PVC sheathed control cable
Ideal for use in low-current control systems and environments with low-level electromagnetic interference.
Designed to ensure reliable performance in electrical control circuits, the KVV cable features polyvinyl chloride (PVC) material for both the internal conductor insulation and the outer sheath. This dual-layer PVC construction provides robust protection against moisture, physical wear, and chemical exposure. It is commonly applied in low-voltage power distribution networks as well as in signaling and monitoring loops.
