    SWA inner sheath unstrippable!

    Bit of a rant - Had to gland off 7 x 25mm 4 core SWAs today - all of which required about 4m of the cores exposed. Turned out to be the worst stuff i've ever worked with - the white inner insulation would just not rip off - tried absolutely everything - in the end had to meticulously pick gently...

    Why no Sheath on Earth conductor ?

    Hi all, Why is it that the earth conductor on twin and earth cable is not made with sheathing already on it ?? I seem to recall back in my college days, my tutor saying it was to reduce manufacturing costs, but surely it costs very little to do this. With flex its made with a sheath already on...
