Our CU/XLPE/PVC unarmoured power cable is precision-engineered in multiple layers, each serving a critical function. From the high-conductivity copper core to the durable PVC outer sheath, every component is selected for long-term reliability:

1.Copper Conductor:Class 2 stranded annealed copper (IEC 60228). Optional: solid conductor for small sizes

2.XLPE Insulation:Cross-linked polyethylene, 90°C rated. Color-coded for easy identification

3.Filler & Binder Tape:Non-hygroscopic filler ensures round cable profile. Polyester binder tape holds cores together

4.PVC Outer Sheath:Extruded PVC type ST1/ST2 (IEC 60502-1). Flame retardant. Optional: LSZH, PE, CPE

 

Sheath Material Options

Beyond standard PVC, we offer specialized sheath materials to meet specific environmental requirements:

• Flame Retardant PVC (FR-PVC): Complies with IEC 60332-3-22/23/24 for flame propagation resistance
• Low Smoke Zero Halogen (LSZH / ST8): Halogen-free compound for public buildings and enclosed spaces (IEC 60754-1/2, IEC 60684-2)
• Polyethylene (PE / ST3/ST7): Enhanced moisture resistance for underground and wet environments
• Chlorosulphonated Polyethylene (CPE): Superior oil and chemical resistance for industrial settings
• Anti-Termite / Anti-Rodent PVC: Special formulation for tropical and underground installations

 

 

Our 0.6/1kV XLPE insulated LV cable is engineered for versatile use across diverse industrial and commercial environments. The unarmoured construction is ideal where the cable is protected from mechanical damage. Key applications include:

 

Industrial Plants & Factories

Power distribution in manufacturing facilities, processing plants, and heavy industry. Resists chemicals, oils, and high ambient temperatures common in industrial environments.

 

Commercial & Residential Buildings

Main power supply and distribution in high-rise buildings, shopping malls, hospitals, schools, and residential complexes. Flame-retardant and LSZH options available for life safety compliance.

 

Power Stations & Switchyards

LV auxiliary power systems in power generation facilities, substations, and switchyards. Reliable performance in electrically noisy, high-voltage environments.

 

Underground Power Distribution

Installed in cable ducts, underground conduits, and trench systems for local energy distribution networks. XLPE insulation provides excellent moisture resistance for underground use.

 

Infrastructure & Construction

Temporary and permanent power for construction sites, bridges, tunnels, and transportation infrastructure. Durable PVC sheath protects against construction site conditions.

 

Indoor & Outdoor Installations

Suitable for both indoor wiring and outdoor installations in cable trays and ducts. UV-resistant sheath options available for prolonged outdoor exposure.

 

What does YJV cable stand for, and how does it compare to N2XY?

YJV is the Chinese cable type designation under GB/T 12706 standard, where:

• Y = XLPE (cross-linked polyethylene) insulation
• J = PVC outer sheath (polyvinyl chloride)
• V = Copper conductor (implied, copper is the default)

N2XY is the equivalent German VDE/DIN 0276 designation, where N=PVC sheath, 2=XLPE insulation, X=copper conductor, Y=unarmoured.

Both are the same cable: copper conductor, XLPE insulation, PVC sheath, unarmoured construction. The difference is purely the naming standard - YJV follows Chinese GB/T, N2XY follows German VDE. We supply both designations and can print either marking on the cable according to your market requirements.

 

Can unarmoured XLPE cable be buried directly underground?

Generally, no - unarmoured XLPE cable is not designed for direct burial. While it can be installed underground, it must be protected inside cable ducts, conduits, or properly prepared cable beds with sand/brick protection.

Direct burial without protection exposes the cable to risks that the unarmoured construction cannot withstand:

• Mechanical damage from rocks, soil movement, or construction activities
• Rodent and termite damage (in certain climates)
• Compression damage from soil pressure and traffic loads

For direct burial applications, we recommend our armoured XLPE cable (YJV22 with steel tape armor, or YJV32 with steel wire armor), which provides the mechanical protection needed for underground installation. If you're unsure about your installation conditions, our engineers can assess and recommend the right cable type.

 

What is the maximum operating temperature of XLPE cable?

XLPE insulated power cable has the following temperature ratings per IEC 60502-1:

• Continuous operating temperature: 90°C (conductor temperature)
• Short-circuit maximum temperature: 250°C (for up to 5 seconds)
• Minimum installation temperature: -15°C (cable should not be installed below this temperature without pre-heating)
• Minimum ambient temperature (operation): -25°C (for fixed installation)

The 90°C continuous rating is a key advantage over PVC cables (rated at 70°C), allowing XLPE cables to carry approximately 30% more current for the same conductor size. This means you can often use a smaller XLPE cable to replace a larger PVC cable, saving both material cost and installation space.

 

How do I choose the right XLPE cable size for my project?

Selecting the correct XLPE cable size depends on several factors. The key considerations are:

• Current carrying capacity (ampacity): The cable must safely carry the full load current without exceeding temperature limits
• Voltage drop: The voltage drop at the far end must be within acceptable limits (typically ≤5%)
• Short-circuit withstand: The cable must handle fault current without damage
• Installation method: Buried, in air, in duct, grouped with other cables - all affect rating
• Ambient temperature and soil conditions: Higher ambient temperatures reduce cable rating
• Future expansion: Consider oversizing for future load growth
