The KVV cable features a copper conductor with PVC insulation and an outer PVC sheath. It is mainly intended for permanent installation in industrial environments, serving applications such as monitoring systems, electrical measurement, signal transmission, and protective circuits. Its voltage rating covers up to 450/750V, with some variants supporting 0.6/1kV as well.
Cable Construction & Specifications
Conductor
Made of annealed copper, available in either solid or stranded configurations
Insulation & Sheath
PVC material is used for both the insulation around each core and the overall external jacket
Number of cores
Ranges from 2 to 61 cores, with 2 to 37 being the most common offering
Conductor cross-section
Available from 0.75 mm² up to 6 mm², with larger sizes possible depending on specific requirements
Voltage rating (U₀/U)
450/750V or 0.6/1kV
Application
Industrial automation systems and manufacturing facilities
Control circuits in power plants and electrical substations
Indoor permanent installations, including cable trenches and protective tubing
Operating Characteristics
Maximum conductor temperature: 70°C for continuous long-term operation
Installation ambient temperature: Should remain above 0°C unless preheating is applied
Minimum bending radius (unarmoured types): Typically 6 × cable outer diameter
Packaging
Finished product + wooden barrel packaging
