Pyro meter tails, can they stay or need replacing?

[Richard Burns]

The cable itself has the cores insulated with compacted magnesium powder,they will take one mighty hammer blow to even damage that insulation

Much better information than I could provide, but I did feel that it should be noted that it is magnesium oxide powder and not magnesium metal powder as the filler.

yeh im thinking that , but its a bit of a pig to do, the meter and box is sat on the out side wall ,which has just had external wall insulation fitted and cant be carved into with out making a mess of it .. and the only other way is back into the living room and through a wall to where the c/u is situated..

If you bend the cable,do so with a sweep rather than try and do an instant 90 degrees (which will probably collapse the outer copper sheath),there is a tool for making the bends but using a bit of rounded wood will do
The pots on the end are star crimped with a soft compound insulation,they do not like being disturbed,so any movement needed should be elsewhere other than the pot

It is possible to remove the gland and pot and re use if you take care,however,the potting compound would need renewing,so best have some handy if you are ever going to dismantle,without the correct tools it would be difficult for a newbie to terminate,however,the stripping,potting and crimping can be done with hand tools if needs be

I asked at college how durable it was, and at the time we had a legend of a guy (Pete Brooks RIP) at HCUK doing practical training.

Me - So Pete, how durable is this Pryor stuff.
Pete - Hmm, very. Watch this!

He proceeded to connect an Supply on one end and a lamp the other draped over an small anvil. He then proceeded to batter the ---- out of it until it looked like a 2 pence peace....bang. The RCD went.

Me - Coooool!

Boring little story but one of my many memories as an apprentice.

What's boring about watching someone hit 10 bales out of energised pyro - dude you need to stay IN more!

I member the exact same scenario at college except the cable wasn't live just connected to an insulation resistance tester.
