Overhead Insulated Underground Cables Aluminium XLPE Cable

Technical Performance
<sub>1. PVC insulated cable conductor maximum temperature rating of 70 ºC, when a short circuit occurs (the longest duration of no more than 5S), the conductor temperature does not exceed 160 ºC. 
2. The maximum rated temperature of XLPE insulated cable conductor is 90 ºC, short (the longest duration of no more than 5S) occurs, the conductor temperature does not exceed 250 ºC.
3. when installing PVC insulated or jacketed cable ambient temperature not below 0 ºC.
4. Perfect chemical stability, resistant against acids, alkali, grease and organic solvents, and flamer retardant.</sub>

PVC XLPE Cable Minimum Bending Radius
<sub>1. Mounting the cable minimum bend radius:
        Single core Armored cable 15D, Unarmored 20D
        Multi-core cable Armored cable 15D, Unarmored 12D
2. Minimum bending radius near the connection box and termination cable:
        Single core Armored cable 15D, Unarmored 12D
        Multi-core cable Armored cable 12D, Unarmored 10D</sub>

Power Cables Advantages
1. Occupies a small area.
    It is usually buried in the soil or laid indoors.
    In trenches and tunnels, the insulation distance between the lines is small, no towers are used, it occupies less land, and      basically does not occupy space on the ground.
2. High reliability.
    Affected by climatic conditions and surrounding environment, transmission performance is stable and reliability is high.
3. It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature and super-      conducting cables.
4. Large distributed capacitance.
5. Low maintenance workload.
6. The possibility of electric shock is small.
