Application
Medium voltage cables for distribution networks; also for connection to generation units and plant and process connection. To be laid directly in ground, outdoors, indoors and in cable ducts.
Construction
● Conductor: Aluminum, 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 or Copper wire
● Outer sheath: Polyvinyl,PO (DMZ1,DMZ2,LSOH,LSZH),Black or Red
Chaircteritics
Good electrical and mechanical properties. Low factor dielectric loss, high insulation resistance. The PO outer sheath allows adequate resistance to UV oil and abrasion.
Different cable type require different structures and materials.
