Stranding (CONDUCTOR)
|
|
|
|
The Copper, Tinned Copper or
Aluminium drawn wires are stranded on a tubular
stranding machine. All stranding machines are
equipped with driven take-up and pay-off ensuring
even tension. These machines are producing upto 1000
mm² conductor. |
|
Bunching
|
|
The fine drawn parallel wires undergo bunching
operations on bunching machines ensuring even twisting and
continuous 25 km smooth conductor. |
|
Insulation
|
|
Insulation for House Wires & Flexibles is carried
out on high-speed twin head extrusion system from with plain,
stripes, spiral and tracer colouring system, online diameter
meter, inkjet printing and online testing system.
The extrusion for PVC, XLPE, insulated power/control and other
cables is carried out on extruders having screw and barrel with
extrusion line having online diameter controllers.
Cables cores are made on state-of-the-art triple head extrusion
system for semicon conductor and XLPE, having computerized
operations ensuring consistency of thickness in all layers.
Before laying-up, the XLPE insulated conductors are steam cured
under standardized condition. |

|
Group pairing Lining Up
|
|
The cores produced are paired on group twinner to
ensure uniform twisting/pairing under controlled tensioning to
produce subunits of 10 /20 pairs. Number of such twisted pairs
(or subunits) are laid-up on drum twister to form a super unit
of 50/100 pairs with coloured tape for identification. |
|
|
|
Laying Up / Taping
|
|
The cores are laid-up on planetary/rigid system on laying-up
machines. |
|
|
|
Armouring (LT Power / Control and Other Cables)
|
|
Strip or Round wire in GI, Copper or Aluminium is
carried out on machines with synchronous drive system ensuring
smooth and more than 90% coverage. |
|
|
|
Sheathing / Jacketing
|
|
Outer sheathing is carried out on extrusion lines with online
diameter controllers, extruder and dies. These extruders are
used for PVC, Zero Halogen / Elastomeric compound and black LDPE
for jacketing. |
