High Voltage Single Core Copper Conductor Cable YJV XLPE Insulated Cable
YJV is an XLPE Insulated PVC Sheathed Power Cable with copper conductors, designed for fixed installations in power distribution networks, industrial plants, and building services.
Cable Designation Breakdown
- YJ: XLPE (Cross-Linked Polyethylene) Insulation
- V: PVC (Polyvinyl Chloride) Sheath
Primary Applications
- Power Distribution: Underground networks, substations, and grid connections
- Industrial Wiring: Motors, transformers, and heavy machinery in manufacturing plants
- Building Services: Main power supply, lighting, and HVAC systems in commercial/residential buildings
- Renewable Energy: Solar and wind power generation systems
Key Advantages
- High Performance: XLPE insulation ensures efficient power transmission with minimal losses
- Durability: Resists aging, abrasion, and environmental stress
- Cost-Effective: Balanced price-to-performance ratio for diverse applications
- Customization: Available in single-core/multicore designs, with copper/aluminum conductors, and optional armor/fire-resistant variants
YJV is a versatile and reliable cable for general power distribution. For harsh environments, consider armored (YJV22), fire-resistant (NH-YJV), or LSZH (WDZ-YJV) versions. Consult technical datasheets or contact our team for project-specific solutions.

Frequently Asked Questions
What does YJV cable stand for?
- YJ: XLPE (Cross-Linked Polyethylene) Insulation
- V: PVC (Polyvinyl Chloride) Sheath
YJV is a power cable with copper conductors, featuring XLPE insulation and a PVC sheath. It is one of the most widely used cables for fixed electrical installations globally.
What are the key advantages of XLPE insulation?
Compared to standard PVC insulation (as in VV cables), XLPE offers:
- Higher Temperature Rating: Continuous operation at 90°C (vs. 70°C for PVC)
- Higher Current Capacity: Can carry more current for the same conductor size
- Better Overload & Short-Circuit Performance: Withstands up to 250°C under short-circuit conditions
- Superior Aging Resistance: More durable over the long term
What are the common voltage ratings?
YJV cables are produced for various voltage levels:
- Low Voltage (LV): 0.6/1 kV (Most common for building and plant distribution)
- Medium Voltage (MV): 6/10 kV, 8.7/15 kV, 12/20 kV, 18/30 kV (For grid and primary distribution)
Where is YJV cable typically used?
It is the standard choice for fixed power installations in:
- Industrial Plants: Wiring for machinery, motors, and transformers
- Commercial & Residential Buildings: Main power supply, risers, and distribution circuits
- Infrastructure: Subways, airports, power stations
- Renewable Energy: Solar farms and wind power connections
Is YJV suitable for direct burial or outdoor use?
- Direct Burial: Not recommended for the standard version. For direct burial, use the armored variant (YJV22) which has steel tape for mechanical protection
- Outdoor Use: Yes, for fixed above-ground installations (e.g., on cable trays, conduits). Its PVC sheath provides basic weather resistance, but for prolonged UV exposure, additional protection is advised
Is YJV flame-retardant or fire-resistant?
Standard YJV has basic flame-retardant properties but is not classified as a flame-retardant (ZR) or fire-resistant (NH) cable. For enhanced safety, specific variants are used:
- ZR-YJV: Flame-Retardant (inhibits fire spread)
- NH-YJV: Fire-Resistant (maintains operation during fire)
- WDZ-YJV: Low Smoke Zero Halogen (minimizes toxic fumes)
What are the main installation guidelines?
- Bending Radius: Minimum 10x cable diameter (single-core) or 12x diameter (multi-core)
- Installation Temperature: ≥ 0°C (to prevent sheath damage)
- Support: Should be properly secured in trays, ladders, or with clamps
- Grounding: Follow standard electrical codes for system grounding
What standards does YJV comply with?
YJV is manufactured to major international and national standards, including:
- International: IEC 60502-1 (LV) & IEC 60502-2 (MV)
- Europe: EN 50502
- China: GB/T 12706
- Other: Can be produced to BS (UK), VDE (Germany), ANSI/ICEA (USA) standards
