0.6/1kV Copper Conductor PVC Insulation PVC Sheathed Power Cable – Low Voltage General Purpose Power Cable

Product Overview

The 0.6/1kV Copper Conductor PVC Insulation PVC Sheathed Power Cable – commonly referred to as NYY cable (European designation) or VV cable (Chinese designation) – is a versatile, reliable, and cost-effective low voltage power cable designed for fixed installation in industrial, commercial, and residential applications.

This cable features a copper conductor for excellent conductivity, PVC insulation for reliable electrical isolation, and a PVC outer sheath for mechanical and environmental protection. Rated at 0.6/1kV, it is suitable for most low voltage power distribution needs, from main feeder lines to branch circuits.

European designation: NYY
Chinese designation: VV
Voltage rating: 0.6/1kV (U₀/U)
Conductor material: Copper (Class 1 or Class 2)
Insulation: PVC (Polyvinyl Chloride) – Type TI
Sheath: PVC (Polyvinyl Chloride) – Type TM
Standards: IEC 60502-1, GB/T 12706, BS 6346, VDE 0276

Key Features

Applications

The 0.6/1kV Copper Conductor PVC Insulation PVC Sheathed Power Cable (NYY / VV) is widely used in the following applications:

1. Low Voltage Power Distribution

• Feeder cables from transformers to main distribution boards (MDB)

• Sub-main cables to distribution boards (SDB)

• Final circuits for lighting and power outlets

2. Industrial Installations

• Power supply to motors, pumps, compressors, and machinery

• Control and auxiliary power circuits

• Factory and workshop electrical systems

3. Commercial Buildings

• Office buildings, shopping malls, hotels, and hospitals

• Power supply to HVAC systems, elevators, and escalators

4. Residential Projects

• Apartment buildings and housing complexes

• Main riser cables and feeder circuits

5. Outdoor and Underground (with caution)

• Cable trays, conduits, and ducts

• Direct burial is possible in dry soil (armoured version recommended for high mechanical risk)

6. Infrastructure Projects

• Street lighting and traffic signal power supply

• Pumping stations, water treatment plants

• Airports, ports, and railway stations

Construction Details

*Note: This is the unarmoured version. For applications requiring mechanical protection (direct burial, rodent-prone areas), armoured versions (NYY-J / VV22 with steel tape armour or SWA) are available.*

Technical Specifications

Available Sizes & Current Ratings (Multi-core, 70°C PVC, in Air)

*Typical values – based on IEC 60502-1. Ratings for 3 or 4 core cables, ambient temperature 30°C, conductor temperature 70°C.*

Values are indicative for multi-core unarmoured cable. Current ratings depend on installation conditions (ambient temperature, grouping, soil thermal resistivity). Please request official datasheet for exact specifications.

NYY vs VV – Naming Convention

*Both designations refer to the same cable construction: Copper conductor, PVC insulation, PVC sheath, rated 0.6/1kV.*

Why Choose PVC Insulation and Sheath?

Note: For applications requiring higher temperature rating (90°C continuous) or low smoke & halogen free properties, consider XLPE/LSZH alternatives.

Single Core vs Multi-core – Selection Guide

*For TN-S earthing systems, 5 core cables eliminate the need for a separate earth conductor.*

Standards Compliance

Optional certifications available upon request:

• CE – European conformity

• CCC – China Compulsory Certification

• UL – For North American market (different construction)

• ISO 9001 – Quality management system

Installation Guidelines

Preparation

1. Inspect the cable for any damage to the PVC sheath before installation

2. Store cables on clean, dry reels, protected from direct sunlight and moisture

3. Preheat the cable if ambient temperature is below 0°C – cold cable can crack the PVC sheath

Pulling Tension

• Maximum pulling tension (copper conductor): Approximately 50 × conductor cross-section (mm²) in Newtons

• Use proper pulling grips (basket weave) – never pull by the insulation

Conduit Fill

• Maximum recommended fill: 40% of conduit cross-sectional area for 3+ conductors

• Use pulling lubricant for long runs

Termination

• Strip back PVC sheath and insulation carefully – do not nick the copper conductor

• Use properly sized copper lugs and terminals

• Apply appropriate torque for termination screws

Testing After Installation

• Perform insulation resistance test (minimum 100 MΩ)

• Conduct continuity test on all conductors

• High voltage test (3kV AC or 3.5kV DC for 15 minutes per IEC 60502-1)

Frequently Asked Questions (FAQ)

Q: What does NYY stand for?
A: NYY is the European designation: N = Standard (VDE), Y = PVC insulation, Y = PVC sheath.

Q: What does VV stand for?
A: VV is the Chinese designation: V = PVC insulation, V = PVC sheath.

Q: Are NYY and VV the same cable?
A: Yes. They refer to the same construction: copper conductor, PVC insulation, PVC sheath, rated 0.6/1kV. NYY is the European naming convention, VV is the Chinese naming convention.

Q: What is the temperature rating of the PVC insulation?
A: PVC insulation is rated for 70°C continuous operation, 100°C emergency overload, and 160°C short circuit (≤5 seconds).

Q: Can this cable be used outdoors?
A: Yes. The black PVC sheath is UV stabilized for outdoor exposure. Light-colored sheaths (white, red, blue) are not recommended for direct sunlight.

Q: Is this cable suitable for direct burial?
A: The unarmoured version (NYY/VV) has limited direct burial suitability. For direct burial in areas with mechanical risk or rodents, we recommend the armoured version (NYY-J / VV22 with steel tape armour).

Q: Is this cable flame retardant?
A: Yes. PVC materials are inherently flame retardant and self-extinguishing. The cable complies with IEC 60332-1.

Q: What is the difference between Class 1 and Class 2 conductors?
A: Class 1 is solid copper (single wire) – used for small cross-sections (1.5-10mm²). Class 2 is stranded copper (multiple wires) – used for larger cross-sections and where flexibility is required.

Q: Do you provide free samples?
A: Yes, we provide free samples of NYY/VV cable. The customer is only responsible for the shipping cost.

Q: What is the typical lead time?
A: Typical lead time is 7–30 days after deposit confirmation, depending on order quantity and conductor size.

Q: Can I get custom printing on the cable?
A: Yes, we support OEM/ODM orders including custom printing (project name, customer logo, sequential metering, voltage marking).

Q: Is LSZH (Low Smoke Zero Halogen) version available?
A: Yes, we offer LSZH versions (N2XH / WDZ-YJY) for applications requiring low smoke and halogen-free properties. Please contact us for details.
