MANUFACTURING |
|
|
In the recent years, there is an increased emphasis on consistency in quality and faster deliveries. This has been
the greatest force behind Polycore to invest in latest technology, plant and machinery to offer a wide range of wires and cables to it’s customers.

WIRE DRAWING |
|
LAYING UP/ TAPING |
|
| The copper/ aluminium wire rods are drawn on high
speed wire drawing machines. The copper wire drawing
machineshave on-line annealing system. This annealing
process acts as an ‘on-line inspector’. The diameter of
drawn wire is maintained within the tolerance limits by
using high precision drawing dies. |
|
Before laying-up, the LT XLPE & EPR insulated conductors are steam-cured in Thermax steam curing station under standard conditions. The cores are then laid up on planetry/ rigid system on laying-up on planetary/ rigid system on laying-up machines. |

|
STRANDING (CONDUCTOR) |
|
ARMOURING |
|
|
|
|
|
|
|
| The copper, or Aluminium drawn wires are then stranded
on tubular stranding machines. All stranding machines
areprovided with driven take-up & pay-off ensuring
eventension. These machines are capable of producing
up to 2 1000mm conductor. |
|
(LT Power. Control and other cables)
Strip or Round wire armouring in GI, copper or alminium is carried out on machines with synchronous drive systemensuring smooth and more than 90% coverage. |

|
|
|
|
|
| BUNCHING |
|
SHEATHING/ JACKETING |
| The fine drawn parallel wires undergo bunching operati
ons on auto mode programmable logic controlling bunch
ingmachines (ensuring even twisting). |
|
Outer sheathing is carried out on extrusion lines with on
line diameter controllers from Zumbach & inkjet printing
machines from Willet. These extruders are used for PVC,
Zero Halogen/ Elastomeric compound & black LDPE for
jacketing. |
|
|
|
| INSULATION |
|
|
| Insulation for building wires & industrial wires is carried
out on high speed twin head extrusion system with plain,
stripes,spiral & tracer coloring system, online diameter
control, inkjet printing & online spark testing system.The
extrusion for PVC, XLPE, EPR insulated power/ control
& other cables is carried out on extruders having online
diameter controllers from Zumbach. |
