Single-Core XLPE Insulated, flame-reterdant PVC Sheathed High Voltage Cable with Aluminum Conductor

Structure:

1. The conductor is aluminum (A), multi-wire compacted, round form, corresponds to class 2 of IEC 60228

• The cross-section of a multi-wire compacted round conductor is 25÷1000 mm²
• The cross-section of a multi-wire compacted round conductor, consisting of 5 sectors, is 1000÷1600 mm²

2. The outer conductor screen is made of extruded semiconducting cross-linked polyethylene
   3. Insulation is cross-linked polyethylene (2X)
   4. Insulation screen is made of extruded semiconducting cross-linked polyethylene
   5. The separation layer is made of the electrically conductive water-blocking tape
   6. The screen of copper wires fastened with copper tape (S)

Minimum cross-section of screen for cables with a conductor cross-section of 25-120 mm² is 16 mm²
Minimum cross-section of screen for cables with a conductor cross-section of 150-300 mm² is 25 mm²
Minimum cross-section of screen for cables with a conductor cross-section of 400-1000 mm² is 35 mm²
Minimum cross-section of screen for cables with a conductor cross-section of 1200 mm² and above is 50 mm²

The maximum cross-section of screen can be set based on the customer's request.

7. The separation layer is made of PETF tape
   8. External protective sheath is made of flame retardant polyvinyl chloride (Y-fl)
