I need to achieve 68 sq mm of copper conductor threaded up the spout of 3/4" bore non-conductive hose in approx 10 metre lengths. Ideally I would like a source of about 20 metres of fine stranded (needs to be flexible) 70mm cross sectional area bare copper wire but it seems like hens teeth. Anyone know any different??????
Best plan so far is to buy 70mm fine stranded welding cable and strip off the insulation (wire will be cooled by other contents of hose and don't want to restrict the flow too much by un-necessarily bunging it up with unwanted pvc.) But the thought of stripping 20 metres of cable is a bit daunting (no I don't want to burn it off!!!) Any cunning plans for cable stripping????
