General information
Standard: AZS 418-2010 (TS İEC 60502-2), TSE K 204 The Russian analogue: APvVng The cable is used for fixed installation in cable lines and the industrial areas. The cables can be laid on dry ground, and have no restrictions on the level difference either. The cable does not spread combustion in case of group cabling.
Single-Core XLPE Insulated, flame-reterdant PVC Sheathed High Voltage Cable with Aluminum Conductor
Structure:
- 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
- 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
