Minimum separation between pipe and cable
I need to run some CH pipe close to an SWA cable (perpendicular to, not
parallel) OSG says cable should not be in contact or alongside. It won't be in contact, but there will be no more than a centimetre gap at best. That feels more than enough gap, given I can fit some of this stuff round the pipe http://www.screwfix.com/app/sfd/cat/...00661&id=62194 Anyone agree/disagree? Ben |

Also, standard foam pipe lagging or quality foam based insulation would do a better job, shiny bubble wrap really doesn't cut it. -- fred Plusnet - I hope you like vanilla |

I reckon I can fit a full crossover in there, so that'll improve things a fair bit. Ben |

But that is ******** . . . . . . . or for a slightly more complete answer, that product relies for its effectiveness on a reduction in radiation from its silvered surface, for this to be effective it needs to mounted in a still air gap of 50mm, no more, no less. If there's a draught it doesn't work, if it gets dirty it doesn't work and if you have something in close proximity it doesn't work. If there is an alleged insulating product less suited to use as pipe insulation I struggle to think of it. As you may have guessed its elaborate claims are one of my pet hates ;-) I reckon I can fit a full crossover in there, so that'll improve things a fair bit. Prob safer, then you could use some 20mm (thick) climaflex (good pipe insulation) to keep the heat off the cable. HTH -- fred Plusnet - I hope you like vanilla |
