Well...maybe it's not too far off topic. PLC's do need a way to move the smoke from point A to point B! I thought I could tap the vast collective knowledge on this forum.
I am working on a control project for a client in India and having a heckuva time finding armoured cable which meets the client's specs here in the U.S.
The cable will need to service an Exd enclosure with double compression cable glands (also certified Exd)...no problem so far.
Here's some basic specs for the cable:
Insulation:
* Primary - 85°C PVC per IS-5831 Type C
* Inner and outer jacket - 90°C PVC per IS-5831 Type ST-2
* Oxygen index >30%
* Temperature index > 250°C
* 600V/1100V
Cable to be twisted and armoured
Armour over inner jacket shall be galvanized steel wire/flat per IS-1554 part I
Single pair/triad: 1.5mm2 7-strand copper conductor
Multi pair/triad: 0.5mm2 16-strand copper conductor or 1.5mm2 7-strand copper conductor
Shield:
* Aluminum backed mylar/polyester tape bonded with metallic side down, helically applied with 25% overlap
* Thickness:
- single pair/triad: <=0.05mm
- multi pair/triad: <=0.075mm
* Drain wire for individual and overall shield: 0.5mm2 bare tinned copper
All multi pair cables shall have 6 pair/12 pairs only
Is anyone familiar with this type of cable? This is the first time I have been required to use something like this.
I have access to some similar cable conforming to British standards, but I have not yet found access to an Indian standard cable here in the States.
I know there are several Indian members on this forum and others have international experience. Could someone please point me in the right direction?
Thanks in advance.
