Features
Key Features of YJLLW03 High Voltage Cable
Superior Sealing & 100% Moisture Barrier
The corrugated aluminum sheath (W) acts as a seamless metal layer with exceptional sealing properties. It not only achieves complete radial water blocking but also effectively preventsexternal moisture from penetrating the insulation, ensuring the long-term stable operation of high-voltage power grids.
Robust Mechanical Protection
Compared to lead-sheathed cables, the aluminum sheath is lighter in weight and higher in strength. Its unique corrugated structure enhances the cable’s crush resistancewhilemaintaining excellent bending flexibility, making it durable even in complex terrains.
Advanced Chemical Resistance & Anti-Cracking：The PE outer sheath (03) offers significant advantages over standard PVC (02) jackets:
Low Water Absorption: Ideal for humid, rainy, or coastal environments.
Environmental Stress Crack Resistance (ESCR): Prevents physical cracks in harsh soil conditions.
Low-Temperature Performance: Remains tough and resilient in cold climates without becoming brittle
High Current Capacity & Heat Resistance
The XLPE insulation (YJ) allows the cable to operate continuously at a rated temperature of 90°C (and up to 250°C during a short circuit). This provides superior transmission efficiencyand a longer service life compared to traditional insulation materials.
Rodent & Termite Resistance
The metallic aluminum sheath serves as more than just a waterproof layer; it is a natural barrier that effectively protects the cable insulation from damage caused by termites and rodents.
Application
- Main Transmission Lines: Ideal for high-capacity underground power transmission in densely populated urban areas where overhead lines are not feasible.
- Substation Connections: Used as the primary link between high-voltage substations and the regional power grid
- High Humidity & Coastal Areas: Due to its PE outer sheath (03) and corrugated aluminum barrier, it is perfectly suited for regions with high water tables, heavy rainfall, or saline-alkali soil.
- Direct Burial & Tunnels: Designed for long-term installation in underground tunnels, cable trenches, or direct burial in soil with high mechanical stress
- Power Plants: Reliable energy out-feed for thermal, hydro, and large-scale renewable energy plants.
- Heavy Industrial Hubs: Supplies stable high-voltage power to steel mills, chemical plants, and mining operations that require uninterrupted energy flow.
