Non Migration of Compound Permitting Vertical Installation. A Tough and Resilient sheath With Excellent fire Resisting Qualities. A non-Hygroscopic Insulation Almost Unaffected by Moisture.
Size :
- 1.5 Sq.mm. to 630 Sq.mm. in 2 to 4 core.
- 1000 Sq.mm in single core
Conductor :
Annealed Bare Electrolytic Grade Copper / Aluminium Conductor conforming to IS:8130:1984. The shaping of Conductor is applied above 10.0 Sq.mm. in Aluminium & 6.0 Sq.mm. in Copper.
Insulation :
Type A PVC Compound capable of withstanding conductor temperature up to 70 degrees C for general purpose insulation & 85 degrees C for Heat Resistant insulation conforming to IS:5831:1984 or XLPE insulation for conductor temperature up to 90 degrees C.
The 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).
- Cores – Red & Black
- Cores – Red, Yellow & Blue.
- Core – Red, Yellow, Blue & Black.(Reduced Neutral Core in case of 3 ½ Core)
- 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 or cores can be identified by numbers by numbers printed on that of the same color.
Laying Of Cores :
Cores are laid up as per the above color scheme. The final lay direction shall be kept the right hand.
Inner Sheath :
The Inner Sheath is applied overlaid up of cores by extrusion/wrapping of thermoplastic material.
Armoring :
It is applied to 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 armor 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.
Outer Sheath :
A final covering of PVC Compound, conforming to IS:5831:1984, is applied over Armouring in case of Armoured Cable or over Inner Sheath in case of Unarmoured Cable, called as “Outer Sheath”.

KV Cable
1.1 KV Cable Suppliers
1.1 KV Cable use stranded copper or aluminum conductors. although small conductor of cables may use solid conductors. The overall assembly may be round or flat. Non-conducting filler strands may be added to the assembly to maintain its shape. Special purpose 1.1 KV Cable for overhead or vertical use may have additional elements such as steel structural supports. Some 1.1 KV Cable for outdoor overhead use may have no outer sheath.
As 1.1 KV cable Suppliers in Kolkata market are produced by us keeping in mind the basic requirements of resistivity and capability. These products are required for the supply of main electric current from one place to another. Its LT Cable Insulation form makes it enduring and helps it in consistent performances. Our offered range is used for earth and unearths purposes as well as various other electric.
