Water ingress in SWA.

Former Community Member over 5 years ago

High all I am new to this forum.

I have a 95mm 4 core SWA cable running to 6 Buildings which are along way apart.

This cable is fed from a feeder pillar up hill to 5 underground joints.

Within the feeder pillar the cable is underground feeding up to 3 160amp fuses and the neutral bar.

On the cable entry water is seeping up the cable and thru the gland causing rusting of the connection plate.

When loop tested at each DB the reading range from 0.29 to 0.76.

But when IR tested L1 is 0.76 L2 is 0.26 L3 is 2.89meg

Do I need to replace the cable.

It's not going to get better, the armour will eventually rust and the cause of the low IR will probably get worse. The questions you need to answer are do you try to find the problem and rectify it or just replace everything and when. As Ebee has said costs, budgets, inconvenience etc start to dictate your options. I would monitor the situation while making your decisions as I assume the invconvenience if the IR gets too low will be high.
