We are doing some R&D, looking at the removal of the oil remaining entrained within the paper insulation following flushing.
I'm looking at a hybrid of thermal desorbtion and air stripping, hence the heat requirement.
The heat would also aid the flushing process but then would only need...
I'm working on the decommissioning of the circuit at the moment.
Energising the cable in any way would not get approval, plenty of 415kv floating around!
Hi all
I'd like to heat up a mile of buried copper cable to roughly 100 deg C.
The centre core is 80mm dia solid copper with impregnated paper insulation.
Maximum spot temp is 150 deg C.
I can expose the core at each end and clamp on a heating element.
I've got plenty of time =...
