Gidday Britspark!,
Welcome to the Forum, great to have you along. [Linked Image]
Yeah, that's one of the good things about Pyro, it's temperature rating is basically the melting point of copper.
And yes I must agree there aren't many things that look as nice as a whole set of Pyro cables nicely laid into and clipped to a cable ladder. [Linked Image]
Kiwi,
The only reason we were trained in it's use here, was because back in the 1950's the Power Board here used to use this cable for Commercial Service Mains (from the intake point to the Switchboard panel) and there are quite a few buildings with this set up still in them around the place here.
Always run as 4 singles, with the sheaths bonded at each end and also at regular intervals along it's length, depending upon the length of the run.
