Concentric Cable Type USEB-90
The useb 90 cable is made up of 2 compacted aluminum conductors and the two cores are parallel, the insulation material of the core is RW90 XLPE, plain copper wire arranged in a spiral shape serving as a service and an overall PVC jacket covering. The neutral is served by the copper wire. The useb wire is designed for use in underground systems with voltages of 600 V or less. The cables are designed for installation underground, either directly buried or in duct systems. On termination poles and during storage, portions of the cable may be exposed to sunlight.

Application of ACSR Conductor USEB-90 Cable
Overhead Power Transmission Lines: ACSR is the preferred choice for long-distance, high-voltage power transmission due to its excellent strength-to-weight ratio, which allows for longer spans between towers.
Distribution Lines: ACSR is widely used in both rural and urban areas for distributing electricity to homes and businesses. Its versatility makes it suitable for various voltage levels and environmental conditions.
Substation Busbars: In some cases, ACSR can be used as busbars in substations, although other materials like copper or aluminum are more common for this application.
