CAI Self-Supporting Cables Application

Name: CAI Cables-Copper Aerial Distribution Cable
SKU: 0

This cable usually used for urban and rural overhead secondary distribution networks, with voltages up to 1000V. They permit longer spans, lower mounting, minimum support, and simplified installation, particularly among trees or in congested areas. It also offers maximum personnel safety and protection against outage. Resistance to abrasion, flexing, and effects of heat, moisture, sunlight and cold assure high dependability through long years of services.
