JKLYJ Medium Voltage ABC Cable

JKLYJ is a medium-voltage overhead insulated cable (ABC – overhead bundled cable) featuring a compact aluminum conductor and cross-lin ked polyethylene (XLPE) insulation, designed for 10kV/35kV AC overhead distribution networks. It replaces bare conductors (steel-cored aluminum stranded wire, aluminum wire), offering enhanced safety, superior insulation performance, longer service life, and lower maintenance costs in urban, industrial, rural, and forested areas.

Compared to traditional exposed overhead lines, JKLYJ offers the following advantages:

• Superior dielectric strength and partial discharge resistance
• Excellent UV resistance, weather resistance, and tracking resistance
• Higher continuous operating temperature (90°C)
• Lighter weight and easier installation
• Lower total cost of overhead network projects

It is the preferred overhead cable for global power companies, EPC contractors, and industrial end-users.

• Urban 10kV/35kV Overhead Distribution Networks – Residential and Commercial Areas
• Industrial Park Main Lines and Factory Overhead Power Supply
• Forests, Mountainous Areas, and High Fire Risk Areas – Replacing Bare Wires to Reduce Short Circuit and Fire Risks
• Rural Electrification and Agricultural Distribution Lines
• Temporary Power Supply, Construction Sites, and Street Lighting Lines
• Renewable Energy (Solar/Wind Power Plants) Overhead Collector Lines
• Not Recommended for: Unsheathed Direct Burial, Underwater, or Highly Corrosive Environments

(Voltage Selection: 10kV for urban/distribution lines; 35kV for long-distance or industrial trunk lines.)

• Conductor Size: Select based on load current, voltage drop, and short-circuit capacity. Larger cross-sectional areas reduce losses but increase costs.
• Spacing and Clearance: Maintain a horizontal spacing of ≥0.6m between cables; maintain a safe distance from trees/buildings.
• Tension Control: Avoid excessive tension; maximum tension of aluminum conductors ≤30×S(N).
• Operating Limitations: Single-phase ground fault duration ≤1 minute (maximum 8 hours per fault, ≤125 hours per year).

Product Advantages

1. Superior Electrical Performance
   • Low-resistance aluminum conductor → Lower power loss, higher efficiency
   • XLPE insulation layer → High dielectric strength, good overvoltage stability, minimal local discharge
2. Excellent Weather Resistance and Aging Resistance
   • Black XLPE formula with added UV inhibitors → Outdoor service life exceeding 25 years
   • Resistant to rain, moisture, ozone, and temperature fluctuations (-20°C to +90°C)
3. High Safety, Suitable for Overhead Networks
   • Insulation design → Reduces the risk of short circuits, , and fire compared to bare wires
   • Excellent anti-tracking performance → Stable operation even in polluted/industrial areas
4. Lightweight and Cost-Effective
   • 30-50% lighter than copper cable → Lower tower load, easier installation
   • Faster deployment, fewer accessories, lower total project cost
