Medium Voltage Cables UNE HD 620 S3

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 or copper, class 2,circular compacted conductors
● Conductor screen: Non-metallic,semi-conducting compound
● Insulation: Cross - Linked Polyethylene XLPE,Nominal Insulation Thickness or Reduced Insulation Thickness
● Insulation screen: Non-metallic,semi-conducting compound
● Metallic screen: Aluminium plastic tape (AL/PET）
● Outer sheath: Polyolefin,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 and abrasion.
Different CPR levels require different structures and materials.
