CU SE-U with XHHW-2 Inners

600V Copper Service Entrance Cable with XHHW-2 Conductors

PRODUCT DESCRIPTION

CU SE-U with XHHW-2 Inners is a 600V copper service entrance cable designed for residential, commercial, and industrial service entrance and feeder applications.

The cable incorporates insulated copper conductors with XHHW-2 insulation, providing 90°C performance in wet and dry locations. The conductors are assembled into a service entrance cable configuration suitable for approved overhead, exposed, or other permitted service entrance applications.

The XHHW-2 insulation system combines excellent electrical conductivity from copper conductors with the thermal stability and moisture resistance of cross-linked polyethylene (XLPE), providing reliable performance for demanding electrical distribution systems.

APPLICATIONS
