KVV - Copper core PVC insulated PVC sheathed control cable
Suitable for weak current control system s or weak current magnetic field interference areas
Engineered for dependable operation in electrical control networks, the KVV control cable is constructed with PVC (polyvinyl chloride) serving as both the core insulation and the external protective layer. This design offers effective defense against common hazards such as dampness, mechanical stress, and corrosive substances. Its typical deployment includes low-voltage supply systems and signal/control loops.
