A superficial appraisal of the cables being pulled by SSE anf Murphy on the Popes Lanes results in the following comments:1) The cable core is solid aluminium. This makes it a tier two product in the wiring industry. Copper would have been a better, safer, and more durables choice. However, cost wins out. Cheap is cheap. Ih this country we have resisted the use of aluminium-cored wires for domestic wiring for decades prefering copper, due to the nature of the higher rate of electrical fires with aluminium. Aluminium is more subject to stress and breakage especially with thermal expansion and contraction of the cable.2) SSE is being slightly shortchanged as the cable lengths though marked and numbered in metres seem to start at three or so metres with a couple of metres missing of the mesaured end which leads one to wonder if the first few metre of ecah reel have already been lopped off by some opportunistic entrepreneur and sold down the scrap merchants or one of the local ;ubs nearby.3) The junction boxes appear to be of thin painted pressed sheet steel and the coating of the boxes is not epoxy or enamel with a limited underground life span. The paint appears to be instead of a galvanised zinc coating.4) Some screening is present in the near the surface of the cable, however, is in minimal and it will be interesting to see how much of the electric field this will screen the surrounding schools, shops and schools from.5) The cable being deployed in this high-voltage infrastructure projecg bears no onvious makers markings, serial numbers, or product codes or products names making me think that it is a low-cost product from somewhere like China, et al., as any kosher European manufacturer would have their name stencilled all over it: marketing!.All in all, not a very auspicious experiece so far. On top of that the extra "bodge holes" that SSE Murphy are having to dig in places like Windmill Road to help ease the cable through its pulling indicate that the ducts that have not been optimally installed to allow trouble-free pulling.Watch this space!
