Hi,
Installation approx 50years old.
Low voltage 230/400V.(UK).
0.5sq in (~300mm2)4core PILC cable.
Cables/Gland Boxes located inside switchroom.
Problem
The black pitch/compound that is used to 'pot' the end of the cable into the cable gland/termination box is leaching / leaking out, and apprears to have been doing so for a number of years.
This is evident by an amount of black pitch running down the side of the cable from the cable box.
The cable is adequate to carry the site load.
There does not appear to be any heat generated at the terminals or within the gland/terminal box, and the cable is cool to touch.
Could this be just natural expansion of the compound during warm/hot weather or something more sinister.
Your thoughts/advice would be much appreciated.
Regards,
mrbj.
