PVC SWA vs XPLE SWA?

[Crosswire]

What on earth is the difference?

 

[Amp David]

The difference is the insulation is made of different materials. XLPE has a 90 degree operating temp as opposed to PVC which is 70

 

[Crosswire]

Ah I see. Does this mean XPLE has a higher ccc?

 

[benji]

ccc? do you mean csa if so it depends who/where it was made , i,ve seen 70mm 4c with the same od. as 95mm 4c

 

[johnboy6083]

if you mean CCC as current carrying capacity, then yes, XLPE does have a slighly higher current rating than PVC.

One has to remember tho that 90 degree cable should be matched with gear

 

[johnboy6083]

very true.

an kept away from 70 degree cables

and kept out of reach of the pikeys.

Tip of the day. To test if sheath is xlpe or PVC drop a piece in water. Xlpe floats and PVC sinks.

Or you could just order the right stuff from the wholesaler

I did mean current carrying capacity.

Good tip mechelec . I will try this

I think you mean the ''Insulation'' not the sheath. As the sheath is PVC on both XLPE and PVC insulated SWA cables mechelec...

 

[Welchyboy]

what are some typical examples of when you would use XPLE over PVC please

would it be in areas with a greater ambient temp for instance???

But take out the copper first.

A boiler house or anywhere with a high ambient temperature.
Or you're trying to cram that bit extra down a cable.

PVC =polyvinylchloride
XLPE=cross linked polyethylene

Sorry yes i did mean insulation

 

[Brightspark2]

Isnt most SWA sold these days XLPE, our wholesalers only supplies XLPE, its been that way for quite a few years now, thats all we have been installing...

 

[The_Wanderer]

Whats the best way of telling difference in existing installation, such as filling out a cert etc? I spent a few times trying to work out if a cable is PVC or XPLE?

''XLPE'' insulation has a generally opaque appearance in it's colour, whereas ''PVC'' insulation has a more of a solid colour appearance!! Best way i can describe it anyway...lol!!

 

[The_Wanderer]

Thanks, yeah i know how you mean and i usually get it sorted in the end. Just curious in anyone had any super tips for telling (other than if you can read it off the sheath ofc)

 

[Amp David]

Usually has it on the outer sheath to

 

[Guest111]

xlpe is horrible to strip as well.

xplecially when it's cold:mad2:
