Customer Challenge:
A utility company in Southeast Asia faced frequent power outages due to tree branches contacting overhead lines during monsoon seasons. Traditional bare conductors required regular trimming of trees, leading to high maintenance costs and downtime.

Uni-Cable provided its 35kV Multi-Layer Tree Wire, specifically designed to withstand direct contact with tree branches without electrical faults. The weather-resistant coating reduced conductor oxidation and extended the lifespan of the cables in the humid, high-temperature climate.
The cables were installed along a 30-kilometer stretch in a dense forest area, significantly reducing maintenance and improving the network’s reliability during severe weather conditions.
