Standard Choice for Outdoor Lines
Overhead power lines are widely used in outdoor transmission systems. They are suitable for high-, medium-, and low-voltage lines. The size range is from 10 to 800 square mm, and the effective cross-sectional area matches this range. The stranding consists of 7, 19, 37, or 61 wires. These product are commonly used in city grids, rural distribution networks, industrial areas, and substation outlets. They are suitable for almost all application environments.
Clean Conductors and Low Loss
The conductor is made of high-purity aluminum or copper. Conductivity meets IACS standards. Resistance remains low, resulting in minimal power loss and high current-carrying capacity. The stranded structure provides flexibility and tensile strength, which is beneficial for installation and long-term operation. The product complies with IEC 61089, BS, and DIN standards. Diameter, resistance, breaking strength, and weight all follow standardized values. These overhead power lines are compatible with global fittings, poles, and insulators.
Tough for All Weather
The cable withstands heat, cold, sunlight, wind vibration, and ice. Aluminum naturally forms a protective oxide layer that prevents corrosion. The overall weight is relatively low, reducing the load on poles. It performs well in long-distance and large-span installations. The failure rate is low, and maintenance costs are minimal. The cable can operate safely for up to twenty-five years in harsh weather conditions. These overhead power lines remain the most widely used and cost-effective option for power transmission.
