As power distribution networks continue to expand into urban, rural, and environmentally sensitive areas, safety and reliability have become critical considerations. Overhead Insulated Cable is designed to address these challenges by providing enhanced protection against electrical faults, environmental damage, and accidental contact.
At HNBF Cable, we manufacture high-quality Overhead Insulated Cables that combine strong mechanical performance with advanced insulation technology, ensuring dependable power delivery in diverse operating conditions.
What Is Overhead Insulated Cable?
Overhead Insulated Cable is an overhead electrical conductor covered with a protective insulation layer, typically made from XLPE or similar materials. Unlike bare conductors, the insulation significantly reduces the risk of short circuits, electric shock, and power outages caused by external contact.
These cables are widely used in low and medium voltage overhead distribution systems, especially where safety and environmental protection are priorities.

Construction and Design Features
Overhead Insulated Cables are carefully engineered to perform reliably in outdoor environments. Their typical construction includes:
- Aluminum conductor for efficient current transmission
- High-quality insulation layer resistant to UV and weather
- Smooth outer surface to reduce contamination buildup
- Optimized flexibility for easier installation
HNBF Cable ensures precise insulation thickness and strong bonding between conductor and insulation for long-term durability.
Key Advantages of Overhead-Insulated Cable
Overhead Insulated Cable offers several important advantages over traditional bare conductors:
Enhanced Safety
Insulation minimizes the risk of electric shock and accidental contact with people, animals, or nearby structures.
Improved Reliability
The insulated design reduces faults caused by trees, birds, and weather conditions.
Weather Resistance
Designed to withstand sunlight, rain, wind, and temperature variations.
Reduced Power Interruptions
Fewer short circuits result in more stable power supply.
Lower Maintenance Costs
Less exposure to external damage means fewer repairs and inspections.
