CORE IDENTIFICATION
For Power cables and Control cables upto 5 cores, the cores are identified by different colours as per
IS 1554 :
Single core : Red, Black, Yellow or Blue
2 core : Red and Black
3 core : Red, Yellow and Blue
3 ½ core : Red, Yellow, Blue, and reduced neutral core in Black
4 core : Red, Yellow, Blue and Black
5 core : Red, Yellow, Blue, Black and Grey
Where the number of cores exceed 5, two adjacent cores are blue for reference and yellow for direction
in each layer. The remaining cores in each layer are grey.
On specific request we can also provide core numbering for Control cables.

CURRENT RATINGS
 
The current ratings given in Tables I to VIII are based on normal conditions of installation described below :
1. Maximum Conductor Temperature
2. Thermal Resistivity of Soil
3. Thermal Resistivity of PVC
4. Ground Temperature
5. Ambient air temperature
6. Depth of laying (to the highest point of cable Laid direct in the ground)		 70℃ for GPPVC Insulation & 85℃ for HRPVC Insulation
150℃ cm/W
650℃ cm/ W
30℃
40℃
75 cms

Cables shall only be operated at their full rating if the minimum current at which circuit protection is designed to operate does not exceed 1.5 times (in the case of cables in air or in ducts) or 1.3 times (in the case of cables laid direct in the ground) the values tabulated, in tables I to VIII.
 
Note :
For cables in air, no reduction in current rating is necessary provided that
  1. The horizontal clearance between circuits is:
    (a) not less than six times the overall diameter of an individual cable, and (b) not less than the overall width of an individual circuit, except that the horizontal clearance need not in any case exceed 150 mm.
  2. The vertical clearance between circuits is not less than 150 mm.
  3. If the number of circuits exceeds 4, they are installed in a horizontal plane.
    However, for installation conditions other than above, current rating factors incorporated in IS 3961 Part II may please be applied.
    The following points should be taken into consideration before selecting any particular size & type of cable:
  1. The system of power & voltage source where the cables are being used.
  2. Conditions of installation at site.
  3. Current carrying capacity of cable.
  4. Voltage drop of the cable.
  5. Short circuit capacity of cable.
  6. Availability of the selected size of cable.

Formula for calculating the
Short Circuit for other durations


Where……..
I1 = Short Circuit Current for one second.
It = Short Circuit Current for t seconds.
t = Duration in seconds.

Maximum Conductor temperature during
Short Circuit is 1600C for both PVC and
HRPVC Cables.
