d. Operating Features:
1)During short circuit (lasting less than 5 seconds) the maximum temperature of the cable conductor shall not be above 250°C Environment temperature should be no lower than 0°C for laying the cable.
2)Bending Radius of the Cable:
Single Core Cable: Non Armored Cable 20D, Armored Cable 15D
Cores Cable: Non Armored Cable 15D, Armored Cable 12D.
Remarks: D means practical external diameter of the cable.

Application:                                                                                                                                                                      
1)These cables are most suitable for direct burial or for installation on trays or ducts, Where there is
a risk of mechanical damage, armoured cables should be used.
2) For laying in ground along route with large difference of level able to bear external mechanical forces.
