General Construction - LT Copper Control Cables
VOLTAGE :
These cables can be used on AC Voltage up to & including 1100 V or DC up to & including 1500 V.
Size : 1.5 Sq. mm. & 2.5 Sq. mm. up to 61 Cores in Control Cable.
CONDUCTOR : Annealed Bare Electrolytic Copper, Solid / Stranded conforming to IS:8130:1984..
Insulation : Conductor are insulated with PVC Compound as per IS:5831:1984. On demand insulation is provided with XLPE also.
Color of Cores : Cores are identified with a color scheme as per IS:1554(Pt-I):1988 as under
- 1 Core : Red, Black, Yellow, Blue
- 2 Cores : Red & Black
- 3 Cores : Red, Yellow & Blue.
- 3 ½ & 4 Cores : Red, Yellow, Blue & Black. (Reduced Neutral Core in case of 3 ½ Core)
- 5 Cores : Red, Yellow, Blue, Black & Grey
In case of cable exceeding five cores, two adjacent (counting and direction cores ) in each layer shall be colored Blue, Yellow and remaining cores grey / Cores can be identified by numbers by numerals on the outer surface of the core as per IS : 1554 : Part-1 : 1988 & IS : 7098 : Part-1 : 1988 or as per customer requirement.
Laying Of CORES : Cores are laid up with a suitable lay. The Final layer direction shall be kept right hand lay.
Inner Sheath : The Inner Sheath is applied over laid up of cores by extrusion.
Armouring : Armouring is applied over inner sheath incase the calculated diameter over inner sheath does not exceed 13 mm, the armour consists of galvanized round steel wires. Where the calculated diameter over the inner sheath is greater than 13 mm the armour generally consists of flat steel. If required, the cable can be manufactured with steel wire where calculated diameter of cable exceeds 13 mm. Single core cables are provided with Aluminium Wire/Strip armouring.
Outer Sheath : A final covering of PVC Compound, conforming to IS:5831:84, 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 HR PVC, FRLS PVC or FRHF Compound depending upon their application.
