(CU/XLPE/LEAD/HDPE)

Description.

Stranded circular compacted or segmental conductor with copper or Aluminum material,
Semi-Conducting layer as conductor screen, XLPE insulation, Semi-Conducting layer
as insulation screen, Semi-Conductive water blocking tape to protect the metallic screen
area from longitudinal water penetration, Lead sheath with suitable thickness to achieve
the required cross sectional area that carry the earth fault current and extruded with HDPE
Sheathed with semi-conducting extruded material.
• Cables are designed and testing according to IEC 60228, 60840 and 60811.
