12.7/22kV Aluminum Single Core Type MV Cable

Single core Type MV cable are designed to resist the harmful effects of chemicals, including oils, solvents, acids, and alkalines. The chemical resistance of the materials used in this cable helps prevent corrosion or deterioration, maintaining the structural integrity and performance of the cable.

characteristics

12.7/22kV Type MV cable can be used in urban underground cable systems. They have corrosion resistance and moisture resistance. They are widely used underground in cities to connect different distribution points and users, and can avoid being affected by groundwater and other corrosive substances.

Feature

• Conductor: Stranded Compacted Circular aluminium conductor as per AS/NZS 1125

• Conductor Screen: Extruded Semi-conductive compound

• Insulation: XLPE

• Insulation Screen: Extruded

• Longitudinal Water blocking : Water blocking tape above and below strippable Semi-conductive compound

copper screen (Optional)

• Metallic Insulation Screen: Copper Wire Screen + helically applied copper tape (E/F current capacity – Based on requirement)

• Metallic Sheath: Lead Alloy (optional)

• Outer Sheath: Extruded Polyvinyl Chloride, Colour: Black

(Alternative Sheath: PVC+HDPE Composite Sheath or LSZH Outer sheath and parameters will change accordingly)

Certification

Copper MV underground cable has obtained SAA certification, with certification numbers: SAA242046 and SAA250307 (available on the certification website). Quality assurance is crucial for large-scale engineering projects. Cables are the foundation of project safety, and selecting certified cables ensures smooth project execution. SAA-certified cables undergo rigorous durability, reliability, and safety testing. They meet stringent technical specifications and can withstand demanding operating conditions.
