Application
Medium voltage cables for distribution networks. They are suitable for laying Indoor, tunnel, cable trench, shaft or buried laying, The cable can withstand mechanical external forces and a certain tensile force, it widely used in transformer stations, electric power plants and industrial plants.
Construction
● Conductor :Copper, class 2, circular compacted conductors
● Conductor screen:Non-metallic,semi-conducting compound
● Insulation:Cross-Linked polyethylene XLPE
● Insulation screen:Non-metallic,semi-conducting compound
● Metallic screen:Copper tape
● Inner sheath:Polyvinyl chloride PVC
● Armour: Non-magnetic steel tape
● Outer sheath: Polyvinyl chloride PVC
Chaircteritics
Good electrical and mechanical properties. Minimal dielectric loss, high insulation resistance. The PVC outer sheath allows adequate resistance to grease, oil and abrasion.
