High Strength for Long Spans

This stranded electrical cable is produced by Jiangsu Jingwei. We have been manufacturing cables for 39 years. This product is a common overhead transmission line cable. It consists of many thin wires twisted together rather than a solid rod. This design provides high mechanical strength and good electrical conductivity. It is suitable for overhead power distribution and long-span installations. The stranded electrical cable performs well under wind, ice, and temperature changes. It resists stretching and sagging over time.

Precision Construction and Strong Materials

The conductor is made of high-purity aluminum or copper strands. The stranding is tight and uniform. Common strand configurations include 7, 19, 37, and 61 wires. A higher number of strands provides greater strength. Size options range from 10 mm² to 1000 mm². This stranded electrical cable is more flexible than solid wire, making it easier to install and suspend for long-term use. All electrical and mechanical performance data comply with IEC 61089 standards. Resistance, outer diameter, breaking strength, and weight are strictly controlled.

Long Life in Tough Weather

This product is resistant to UV radiation, high temperatures, low temperatures, and corrosion. It also withstands wind vibration and ice accumulation. It can be used in coastal areas, industrial zones, high-altitude regions, and extremely cold environments. The stranded electrical cable has a service life of 25 to 30 years. It offers good heat dissipation and high current-carrying capacity, with low line losses. Installation is simple and maintenance costs are low. It is suitable for urban power grids, rural distribution lines, industrial parks, and new energy projects.
