Product Feature
Our bare overhead conductors consistently lead the industry, actively exploring capacity expansion and energy-saving technologies. We help customers increase line capacity by replacing conductors with high-capacity ones, avoiding the high costs of building new transmission corridors. For complex outdoor environments, we have developed UV-resistant and weather-resistant "anti-aging" bare overhead conductors, significantly extending product lifespan. Simultaneously, we equip our bare overhead conductors with advanced anti-galling clamps, effectively reducing conductor sway under wind conditions and improving line operational stability. We also apply dynamic capacity expansion technology, combined with a conductor temperature monitoring system for real-time monitoring, to fully exploit the short-term overload capacity of the line.

FAQ
How to select the appropriate bare overhead conductor on requirements?
- Selecting suitable bare overhead conductors a comprehensive consideration of voltage level, environmental conditions, and technical and economic efficiency.
- For distribution lines of 10kV and below, JKLYJ type overhead insulated conductors are preferred to improve safety in urban and densely populated areas. For 35kV–110kV transmission lines, LGJ type steel-cored aluminum stranded wire is recommended, balancing conductivity and mechanical strength. For 220kV and above ultra-high voltage systems, two- or four-split conductors are recommended to reduce corona loss.
- From an environmental perspective: high-strength conductors should be selected in windy and heavy icing areas. Corrosion-resistant conductors should be used in coastal or industrially polluted areas. Lightweight, high-strength conductors are recommended for long-span sections to reduce sag.
- Furthermore, selection requires verification of current carrying capacity, voltage drop, and mechanical strength. The cross-section should be optimized based on economic current density to balance initial investment and long-term operating costs.
