LT Control Cables

Control cables are used in industrial power or control circuits for conveying electrical signals to the associated devices. Control Cables differ from Power Cables in their application. They are used to carry control signals of low power strength, but can be subjected to severe working temperature conditions like heaters, boilers and can be exposed to oil, chemicals and other solvents. The wide range of control cables offered by us are used for electrical distribution system such as generating stations, sub-stations, industrial applications, indoor outdoor projects. We can also provide the customized range of the control cable as per the specifications, detailed by our clients.

PVC Insulated Unarmoured or Round Wire/Flat Strip Armoured Control Cables Upto & Including 1.1 KV.

Voltage : These cables can be used on AC Voltage up to & including 1100 V or DC Upto & including 1500 V.

Size : 1.5 Sq. mm. & 2.5 Sq. mm. up to 61 Cores in Control Cable.

Conductor : Annealed Bare /Tinned Electrolytic Copper conforming to IS:8130:1984.

Insulation : Conductor are insulated with PVC Compound as per IS:5831:1984.

Color of Cores : Cores are identified with a color scheme as per IS:1554(Pt-I):1988 as under :
2 Cores - Red & Black
3 Cores - Red, Yellow & Blue.
3 ½ & 4 Core - Red, Yellow, Blue & Black. (Reduced Neutral Core in case of 3 ½ Core)

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 numbers printed on that of same color.

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/wrapping of thermoplastic material. The Insulation, Inner Sheath can be HR PVC, FRLS PVC or HFFR Compound depending upon their application.

Armouring : 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 armouring is provided , where the calculated diameter under Armour is 13.0 mm. Above this, armouring is either round wire/steel strip.

Outer Sheath : A final covering of PVC Compound, conforming to IS:5831:84, is applied over Armouring in case of Armoured Cable or over Inner Sheath in case of Unarmoured Cable, called as "Outer Sheath".

The Insulation and Sheath material can be HR PVC, FRLS PVC or HFFR Compound depending upon their application.

Current Rating : Current Carrying Capacity of these cables are as per IS:3961{Pt-II) : 1967.

Standard Specifications : IS 1554:1988 (PART -1),BS:6346:1989,IEC 227-I, III

Quality Assurance : Quality Standards are built in every Svarn product. Svarn cables are subjected to a series of required tests in our well equipped laboratory. Besides the rigid tests and checks at every stage from raw material through manufacturing stages and finally up to the finished product.
