VVR Flexible Copper PVC Power Cable for LV Equipment and Portable Supply

Product Description

VVR is a flexible copper core PVC insulated PVC sheathed low-voltage power cable suitable for mobile equipment, temporary power supplies, and fixed wiring requiring extra flexibility. Available in a full range of sizes, with fast delivery and export-standard packaging, it meets global project needs.

Core Value

VVR is the ideal choice when your wiring requires flexibility and ease of handling, but you don't want to use special rubber cables.

Product Overview

VVR is a low-voltage flexible power cable typically featuring a finely stranded copper core (flexible grade), PVC insulation, and a PVC outer sheath. The "R" indicates a flexible conductor design, making VVR easier to bend and wire than standard rigid building power cables. It is widely used in portable power connections, mobile machinery, temporary field power, and fixed installations requiring large angles of bending, vibration, or frequent repositioning, where standard non-flexible power cables are inadequate.

Low Voltage Ratings

Typical Voltage Rating:

0.6/1 kV (depending on project standards)

Common Applications:

Low-voltage power supply for equipment, temporary power supply, and flexible fixed wiring

Ensure that the voltage rating and construction meet the standard requirements in your Bill of Quantities (BOQ).

VVR Application Scenarios

Common Applications

• Portable power supplies and expansion components (where permitted by local regulations)
• Power connections for mobile machinery and equipment
• Temporary site power distribution within protected wiring
• Workshops, warehouses, factories, and maintenance areas requiring frequent mobile equipment
• Equipment rooms requiring repeated bending of cabling during installation
• Cable trays and conduits in cable trays and conduits when additional flexibility can reduce installation time

Typical Installation Considerations

• Designed for flexible cabling and easier operation
• Not suitable for continuous high-frequency dragging or heavy-duty dragging applications; for harsh dynamic conditions, rubber-sheathed cables or dedicated drag cables may be more suitable.

Why Buyers Choose VVRs

• Flexibility, faster installation

  Fine stranded conductors make pulling, bending, and termination preparation faster, especially in confined spaces.

• In many projects, it is a cost-effective alternative to rubber cables.

  PVC/PVC construction offers practical flexibility while controlling costs.

• Reliable copper core performance meets low-voltage load requirements.

  The copper core conductor provides stable conductivity for typical low-voltage equipment circuits and distribution connections.

• Ideal for distributors and EPC procurement.

  Common sizing and repeatable construction design facilitate inventory planning and phased delivery.

Process and Manufacturing Notes

• Fine Copper Stranding

  Multiple strands of fine copper are stranded together, achieving good flexibility while controlling conductor resistance.

• PVC Insulation Extrusion

  The insulation layer uses controlled thickness and concentricity to ensure stable dielectric properties.

• Core Assembly

  The cores are stranded to maintain geometric stability, improve roundness, and reduce pulling friction within the conduit.

• PVC Sheath and Marking

  An extruded outer sheath protects the cores and provides abrasion resistance for normal field operations. Clear markings are applied to the sheath for easy traceability.

• Routine Inspections

  Typical inspections include conductor resistance, insulation thickness, spark testing, voltage testing (if required), dimensional inspection, and sheath integrity.

SELECTION GUIDE

1. Confirm voltage class and the governing standard in your project documents
2. Define usage: portable equipment, temporary power, or flexible fixed installation
3. Choose core count based on single-phase or three-phase design and neutral/PE requirement
4. Select cross-section by load current, distance, grouping, ambient temperature, and voltage drop limit
5. Confirm mechanical conditions: bending radius needs, vibration, and pulling method
6. If the route has underground sections or higher mechanical risk, consider armored options where required by code

FAQ

Q1 What is VVR cable mainly used for

A VVR is used for low-voltage power connections where flexibility is needed, such as movable equipment, temporary power, and installations with tight bends.

Q2 What is the difference between VVR and VV

A VVR uses a flexible stranded conductor design for easier bending and handling, while VV is commonly specified for fixed installation with less emphasis on flexibility.

Q3 Is VVR suitable for continuous movement

A VVR is designed for flexible routing and occasional movement. For harsh, continuous high-cycle dragging or trailing service, a dedicated trailing or rubber-sheathed cable may be more appropriate.

Q4 What voltage rating should I choose

A Match the voltage class and construction to your project standard and application. Many projects use VVR in the 0.6/1 kV class, but the correct grade must follow your BOQ.

Q5 What sizes are most common

A 0.75 to 6 mm2 is common for light equipment and controls, while 10 to 35 mm2 is common for equipment power. Larger sizes are used for higher-load feeders depending on distance and voltage drop.

Q6 What information is needed for fast pricing

A Voltage class, standard, core count, size list, total meters, application type, packing preference, destination, and document requirements.
