Applications and Route Conditions
XWA manufactures this voltage class for medium voltage distribution feeders, transformer substations, industrial power intake, wind and solar collection circuits, mining distribution routes, municipal underground networks and duct or tray installations.
Larger conductor sizes, thermal spacing and bonding design often point to single-core cable. Compact routes, shorter runs, indoor substations and installations that need combined cable handling often use three-core cable.
Underground or wet-route conditions can require PE sheath and water-blocking options. Projects that include smoke and halogen performance requirements can specify LSZH sheath.
