Re terminating ancient cables

Martyn
Hi Folks, 


So I may have a job in the offing where I will need to temporally re terminate these 3 cables, the one on the right is only 1m long so I’ll just replace it. 


The other two are rising mains from the 1940’s each feeding 20 flats, I believe them to be armoured PILC’s though happy to be corrected, the lead is being used as the earth. 


Has anyone re terminated similar and are there any pitfalls that may scupper me? 


The re termination will only be temporary whilst the new building network is being installed.89f8b92115c4d5d4e672a2d7771fc855-huge-a8ae4b2d-f17a-4e4e-a594-4469fa0801a0.jpg



Cheers

    I can’t remember where the asbestos is in that type of cutout, but it is likely to be in the phase barriers at least. It is conceivable that the DNO will want to cut it out and bag it, without opening it, due to the risk of releasing asbestos fibres in to the atmosphere. The usual method is a “dig and cut” to isolate it outside, then suitable cutters on the cables inside. If it has been obviously interfered with, for example the DNOs seals missing, they may request an asbestos survey of the immediate area first. 


    As OMS has stated, I would have expected the SWA to have an outer hessian wrapping, which may have failed and fallen away due to age, rodent attack, or overheating. If overheating was the cause, the insulating papers may be dry and brittle, the impregnating oil having long since dried. 


    Regards,


    Alan.
