Duplex Cable Aluminum Conductor Overhead Service Drop Cable Wire 600V Application
Aluminum duplex overhead cables are manufactured and designed for overhead power distribution as compared to the conventional bare conductor overhead distribution system.
Duplex aluminium overhead cables have two conductors: one for electrodes, and the other one as a messenger (neutral conductor).
The product is a new type of aerial cable for power transmitting . It is extensively used in overhead power transmission line. It improves the safety and reliance of electrified wire netting . It is primarily used on lighting, outdoor lighting,and temporary service for construction . Duplex cables are used in single-phase power lines and the conductor temperatures no exceed 75℃ for polyethylene insulated conductors 90℃ for crosslinked polyethylene (XLPE) insulated conductors.
