View MoreProduct Overview Rated voltage 450/750V and below PVC insulated PVC sheathed control cable (PVC control cable) is the most fundamental and core signal transmission product for industrial automation, mining enterprises, energy/transportation, and high-rise building wiring. Used for control, monitoring, and protection circuits at AC rated voltages of 450/750V and below. Using PVC for both insulation and sheath, this cable offers excellent electrical insulation, good chemical stability, and high cost-effectiveness. For complex industrial electromagnetic environments and mechanical installation requirements, the product includes shielded (KVVP series), flexible (KVVR series), and armored (KVV22 series) variants, with flame-retardant (ZR) or fire-resistant (NH) grades available for fire safety needs.
Implementation Standards
- GB/T 9330-2020: Plastic insulated control cables (core standard)
- GB/T 19666-2019: General requirements for flame-retardant and fire-resistant properties
- GB/T 3956: Cable conductor DC resistance requirements
Model Code Meanings
- K: Control cable series identifier
- V (1st): PVC insulation
- V (2nd): PVC sheath
- P/P2/P3/P4: Shielding — P: copper wire braid; P2: copper tape wrap; P3: aluminum/plastic laminate; P4: copper wire braid + copper tape double composite
- R: Flexible conductor (multi-strand fine copper wire)
- 22/32: Armoring — 22: double steel tape; 32: fine round steel wire
- ZR/ZA/ZB/ZC: Flame-retardant grades A/B/C
- N: Fire-resistant
Specifications
Conductor: High-quality annealed oxygen-free copper.
- Core count: 2 to 61 cores
- Cross-section: (2~61) x (0.75~2.5) mm²; (2~19) x (4~6) mm²; (2~7) x 10 mm²
Core Technical Parameters
- Rated voltage (U0/U): 450/750V
- Max conductor working temperature: 70°C
- Laying temperature: >= 0°C (preheat if below)
- Min bending radius: Unarmored >= 6D; armored or copper tape shielded >= 12D; shielded flexible >= 6D
- AC voltage test: 3000V / 5 min without breakdown
Cable Structure
- Conductor: Class 1 (solid), Class 2 (stranded), or Class 5 (flexible)
- Insulation: PVC, color-coded or marked for identification
- Shielding (shielded type): Suppresses EMI for signal accuracy in strong EM environments
- Armoring (armored type): Steel tape or wire for direct burial or areas with mechanical damage risk
- Outer sheath: Special PVC with moisture, abrasion, and corrosion resistance
Application Areas
- Industrial automation: Sensor, actuator, PLC control panel signal connections
- Power systems: Substation monitoring, metering, and secondary circuit wiring
- Public facilities: Building intercom, security, air conditioning control in fixed systems
- Underground: Armored types for cable trenches, tunnels, and direct burial
Selection Guide
- General use: KVV or VLV
- High EMI: KVVP or KVVP2 for system stability
- Flexible/space-limited: KVVR or KVVRP
- Mechanical damage risk: KVV22 steel tape armored
- Fire-critical locations: Check ZA/ZB/ZC flame-retardant grade or NH fire-resistant performance
