Hot SWA gland

[HEARDY]

I have a hot SWA Gland on a 11kV cable. The cable has a SWA Gland on each end. I was under the belief that this would create a current circuit. There is 3 trefols running in parallel.

Any suggestions

Look like several pyro cables (Orange) to the right in the first picture all grouped together? Do they get warm too?

Sheath voltages are down to current and length not voltage. At that length and because you say there can be sparking at the glands, I would consider earthing at one end and fitting voltage limiters at the other.
I am a bit confused as to why you think they are earthed at both ends but you can cause sparking between the glands, sparking would indicate not being earthed/bonded. could it be that the glands are isolated but arcing in one gland is causing heating?

Only one end of the singles should be earthed. It’s usual to use a Paxoline gland plate at the switchgear.
