XLPE (Cross-linked Polyethylene) insulation offers significantly higher operating temperature (90°C vs 70°C for PVC), better dielectric properties, higher current carrying capacity, and longer service life. XLPE is the preferred choice for medium voltage applications (above 1kV) while PVC is typically used for low voltage cables.
Yes, aluminum conductor XLPE insulated cables with proper PVC or PE outer sheath are suitable for underground installation including direct burial and cable trench. The XLPE insulation provides excellent moisture resistance, and the outer sheath offers mechanical protection against soil pressure and environmental factors.
Our 12/20kV cables comply with IEC 60502-2 (power cables with extruded insulation for voltages 6-30kV), IEC 60228 (conductors), and IEC 60332 (flame retardance). Additional standards including BS and ASTM are available upon request for specific regional requirements.
Selection depends on multiple factors: load current (A), voltage drop limits, short-circuit rating, installation method (buried/air), ambient temperature, and grouping factor. Our engineering team provides free sizing calculations — please contact us with your project specifications.
Under normal operating conditions (90°C max), XLPE insulated power cables have a design life of 30-40 years. Actual service life depends on installation conditions, load cycling, environmental factors, and maintenance practices.
