L.T. HEAVY DUTY CABLES These cables are suitable for use on Ac single phase systems for the rated voltage up to and including 1100 Volts. These cables can be used on DC system for rated voltage up to and including 1500 Volts on earth.
CONDUCTOR The most acceptable metals for conductors are copper and Aluminium due to their higher conductivity and ductility. As copper has got higher affinity for Sulphur, it corrodes in the atmosphere where Shulphur fumes are present . In these conditions tinned copper should be used.
Aluminium Oxide film which is always present on Alminium surface acts as a barrier and it protects the Aluminium conductor from corrosion in fumes laden atmosphere.
CONDUCTOR CONSTRUCTION The most Economical Construction is solid conductor i.e. conductor is made of one Single Wire as the area of Conductor is increase; Solid conductor becomes more stiff and hence difficult to handle. In this case stranded construction is adopted. Here the conductor is made of numbers of strands. The strands are arranged in spiral layers in 1+6+12 +18+.................. formations. This construction provides more flexibility. Where crimping of lugs are required, the conductor has to be of stranded construction only.
To Economise in insulating material, weight and overall diameter, shaped conductor are employed in bigger sized cables. Here the strand conductor is shaped in to a segment of a circle so that when all the cores are laid they form a complete circle.
INSULATION The PVC (Polyvinyl Chloride) covering over conductors is called insulation and is provided by extrusion process only. The insulated conductor is called core. We are using two types of compound for insulation:-
Insulation with PVC compound which is suitable for 70o C continues operation.
Insulation with PVC compound which is suitable for 85o C continuous operation.
THE FOLLOWING COLOUR CODES ARE USED FOR IDENTIFICATION
Single Core : Red, Black, Yellow or Blue
Two Cores : Red and Black
Three Cores : Red ,Yellow ,and blue
Three & Half : Red, Yellow Blue and Reduced Neutral Black
Four Core : Red , Yellow, Blue, and Black
Five Core : Red , Yellow, Blue , Black and Grey.
Six Core : Two adjacent cores Blue and Yellow (Counting and direction Core) & remaining Grey in each layer.
OUTERSHEATH The PVC covering on Armouring in case of Armoured Cable and over the inner sheath in case and over the Inner Sheath in case of Unarmoured Cables is called Outer Sheath.
Outer Sheath with PVC compound which is suitable for 70 degree continuous operation
Outer Sheath with PVC compound which is suitable for 80 degree continuous operation.
PVC has got fire retarding properties due to its Halogen content. The fire in the cable gets extinguished immediately on removal of the source.
DELIVERY LENGTH The cables are generally delivered in 100 Mtrs. Coils wrapped with Polyethylene / Hessian. The bigger size cables are supplied on wooden frames.
PVC insulated single core and multicore flexible cables have a wide range of application in machine tools, appliances, control panels, machinery and industries of every nature.
Conductors The conductors are drawn from bright electrolytic grade copper, and annealed conductors are bunched together.
Insulation Bunched conductors are insulated with specially formulated, in-house developed PVC compound with high insulation resistance values. The insulation process is carried out on modern high speed extrusion lines with high accuracy, ensuring consistency in performance.
Sheath In case of multicore cables, the insulated cores are laid up to form the core assembly. The inner cores are coded for ease of identification as per National/International coding practices. The sheathing is provided with specially formulated PVC compound to facilitate not only ease in stripping but also to withstand mechanical abrasion while in use.
PVC insulated single core and multicore sheathed cables are manufactured as per IS 694/1990, in sizes from 0.5 sq.mm. to 50 sq.mm. in single core and in sizes 0.5 sq.mm.to 4 sq.mm. upto 5 cores. These sizes carry ISI mark and are duly approved by FIA/TAC. The rest of the sizes also generally conform to IS: 694/1990.
Cables as per BS 6004/1991 and BS: 6500/1990 are also available for export market. Special purpose cables in screened construction can also be made available.
LOADKING 3 Core Flat Cables are manufactured for critical space requirement, protection against indefinite immersion in water under specified conditions, protection against rain-water and against ingress of small solid foreign bodies.
LOADKING 3 Core Flat Cables are produced from best quality electrolytic copper, which is drawn, annealed on-line and bunched on automatic machines to ensure flexibility and uniform resistance. The conductors are insulated with a special grade of PVC on sophisticated co-extrusion lines. Outer sheath consists of highly abrasion resistant PVC compound impervious to grease, oil and water etc.
Load King Wire Industries manufactures a wide range of cables suitable for purpose of Instrumentation. In the projects related to power generation & distribution, chemical, fertilizer, sugar Industries and various other types of engineering industries. The process instrumentation plays a vital role in measurement and control of the process.
Shield is provide to prevent harmful electrostatic interface. There are three basic reasons for providing an electrostatic shield in a cable. The first important reason concerns the need to keep external electrical disturbances from affecting the signal in the cable. The second reason is to prevent the signal in the cable from being detectable at location other than at the cable ends. And the third reason is the elimination of unwanted transfer of signal between circuits in the same cable.
For the inter connection of data processor, instruments and microcomputers where signal interface is a consideration, cables are generally screened. Microcomputers require medium speed data transmission and for these, interfaces with screen twisted pair cables are suitable. When signal speeds are low a braid screen is sufficient but for higher speed a foiled screen or composite foil and braid screen is more suitable. A further refinement is to use individually screened pair to minimize the effect of cross talk, thus making possible the transmission a data over long distances.
"Load King" with its efforts in maintaining quality, stringent in process control during process, and having the well-equipped cable designing engineers, is proud to say that we are capable to manufacture and supply the Instrumentation Cables, conforming to Indian/ British/ International standard or customer's specific requirement desired by projects.
