What are the key differences in the selection criteria for outdoor direct-buried cables and conduit cables?
The selection criteria differences between outdoor direct-buried and conduit cables center on mechanical protection and environmental isolation. Direct-buried cables require inherent mechanical robustness, typically utilizing Steel Wire Armor (SWA) or Steel Tape Armor (STA) to survive crushing forces, rock migration, and rodent attacks without external enclosures. Conversely, conduit cables rely on external rigid metal or […]
