Color Of Cores
Cores are identified with a color scheme as per IS:1554(Pt-I):1988 as under :
- Cores - Red, Black, Yellow, Blue or Natural (non-pigmented).

Laying Of Cores
Cores are laid up as per the above color scheme. The final lay direction shall be kept right hand.
The Inner Sheath is applied over laid up of cores by extrusion / wrapping of thermoplastic material.
It is applied over inner Sheath. It may consist of galvanized Round Steel wires or galvanized Flat Steel Strips conforming to IS:3975. Round Wire armoring is provided , where the calculated diameter under Armour is 13.0 mm. Above this, armoring is either round wire/steel strip. In single core cables used in AC systems, armoring I done by non-magnetic hard drawn aluminum wires / strips
A final covering of PVC Compound, conforming to IS:5831:1984, is applied over Armoring in case of Armored Cable or over Inner Sheath in case of Unarmored Cable, called as "Outer Sheath".
The insulation, inner sheath & outer sheath can be of HR PVC, FRLS PVC, FRHF (Flame Retardant Halogen Free) or ROHS Compound depending upon the application.
