MANUFACTURING PROCESS

 
( FLOW CHART )
       
   
Rods are drawn on wire drawing machines and to form a wire of required diameter.
 
       
    Drawn copper wires are annealed  
      Test on Wire  
   
Wires are concentrically stranded & sector an shape compacted (except smaller than 16 and sq.mm. sizes) to form a conductor of cable.
 
Test on PVC
compund (Checks)
                   Test on stranded conductor.  
                     Conductors are insulated with PVC a / XLPE as required.                  (Extrusion)  
                                        Test on cores  
    Cable curing is done by a special process a a d to get cross-linking of polyethylene.  
       
    Insulated cores are twisted together & laid as up (For Multi-core cables).  
     
    Laid up cables are inner sheathed with PVC an or XLPE Compound either by extrusion or an by PVC tape wrapping.  
       
   
Insulated single core or inner sheathed multi ansingle core core cables are armored with hard drawn Al a Armored Wire/strip or gal. steel wire/strip as applicable
 
   

Unarmored or Armored cables are sheathed
unarmored with PVC or XLPE compound by extrusion.

 
     Test on PVC Compound.  
       
   
Finished cables are tested for Routine, Type a & Acceptance tests before packing.
 
       
    All tested and passed cables are packed in and required sized drums prior to dispatch.
