Product Description
KVVR: Flexible PVC/PVC Control Cable : Product Description and Specifications
Designated for secondary circuits and signal transmission, the KVVR series integrates Class 5 Fine-Stranded Copper Conductors (per IEC 60228) to distinguish itself from the standard rigid KVV model. This flexible structure ensures compliance with tight bending radii requirements, making it the mandatory specification for internal wiring in switchgear, instrumentation, and compact automation units. The optimized PVC jacket facilitates installation in confined spaces where static flexibility is critical.

Advantages
KVVR: Flexible PVC/PVC Control Cable : Benefits and Features
- Easy to Route: The Class 5 stranded copper core handles tight bends and crowded trays without stiffening up.
- Vibration Proof: Unlike rigid cables, the flexible structure absorbs machine vibration, preventing loose connections.
- Installer Friendly: Soft PVC jacket strips clean and fast; numbered cores make circuit tracing simple.
- Reliable Specs: Rated for 300/500V and operational from -20°C to +70°C.

Production Processes Of Control cable
Control cables are manufactured via pressure extrusion to lock in PVC density. Quality control goes beyond standard metrics: we conduct mandatory oil resistance and bending tests on each production lot. This verifies actual performance against IEC specs, ensuring durability in real-world automation environments.
Packing For Shipment
To meet various transportation needs, there are many methods of packaging that can be used.
Have more questions?
Q: Difference between KVV and KVVR?
A: Conductor Class.
KVV: Rigid (Class 1 or 2). Hard to bend.
KVVR: Flexible (Class 5). Fine-stranded copper. Mandatory for tight instrument panels and small bending radii.
Q: Outdoor Installation?
A: Requires Conduit. Standard PVC is not UV-stabilized. Direct sunlight exposure will degrade the insulation. Must be routed inside pipes or protective channels.
Q: Is it Shielded?
A: No. Standard KVVR is unshielded. For EMI/RFI noise immunity, specify model KVVRP (includes Copper Braid Shield).
Q: Drag Chain / Robotics Use?
A: Prohibited. KVVR is designed for Static Flexibility (routing only). For continuous dynamic motion (millions of cycles), upgrade to TRVV (Towline Cable).
Q: Core Identification Method?
A: Standard Coding:
≤ 5 Cores: Color-coded insulation.
> 5 Cores: Black insulation with White Numbering for easy circuit tracing.
Q: Voltage Rating?
A: 450/750V. Covers standard industrial control signals and low-voltage power distribution.
Q: KVVR vs. RVV?
A: Application Difference.
RVV: General purpose cord (Appliances). Low core count.
KVVR: Industrial Control. Compact OD, supports high core counts (up to 60+), engineered for machinery control logic.
Q: Oil Resistance?
A: Standard Grade. Basic resistance only. For environments with heavy oil immersion, please specify “Oil-Resistant Compound” upon ordering.
