Cable Terminations

02/27/2014 5:19 AM

Hi there!

Anyone know what are these cable terminations? The voltage phase-phase is 11kV.

Best regards,Boris

Looks like alloy or lead sheathed singles.

Someone's done a nice job of plumbing them to the cones and taping the outer serving. All over painted, my electricians mate would paint the plumbed wipe with the relevant phase colour.

Hope whoever did the job was proud of it, it's good workmanship.

Yes, these are 11kV PILC, wiped gland terminations. The flange mounted to the switchgear is a brass cone, plumbed (lead wiped), to the lead alloy sheath of the cable, with a bell wipe above the cable clamp where the armour has been cut back. (This becomes a water seal and an earthing point for the lead sheath and the wire or steel tape armour.

On mines in South Africa they are known as Rand Mine Glands, (the brass cone gland), and were very popular with mines. However, this is not in S Africa and it looks like it may have been a BICC job. (Only a guess due to the workmanship).

I also have to agree, this is lovely workmanship and the lad(s) who manufactured these should be proud of the work.

Hi,

TonyS and IQ, out of curiosity, could you expand on what makes it good workmanship? What could have been not as good a job for example?

Thanks

Oh Boy, I should not do this. Lead wiping is an art. Something that the 21st century has killed off for many. A person who can work with hot lead in molten form and create a piece of workmanship, without melting the cable sheath, which causes leaks and cable failure, and can meld the metals together and offer terminations, such as you have there, has to be good at his craft. Not what is classed a cable jointer or terminator by today's standards, (They are in my opinion NVQ's, Not very Qualified).

The young trades persons don't, can't and won't do this type of work as they don't have the skills, and the skills are not taught anymore. Also HSE does not like persons working with lead alloys in molten states, it is frowned upon, dangerous, and unhealthy.

Having done this art form and taught the newer systems, it is a pleasure to see workmanship of this caliber, neat, tidy, uniform, maintained and aesthetically pleasing to look at. And of course they work and have probably worked for a good few years now. (Curious, when were they made?).

You will know a bad job when you see it. What you have is a lovely work piece and probably very soon someone will change the cables, the terms will be thrown out and the metal salvaged for scrap. And you will never see this type of workmanship, ever again.

I gave my critique, I stand by it. What do you think of the terminations?

I used to Strip lead sheathed cables and make weights for fishing in Zimbabwe...

So if what we can see in the photo is a bank of very nicely tailored and finished sheath then the electrical conductors and the conductor terminations are within...right?

What's the inside of these look like?

Just to give a preview of a topic I'm writing for a UK site. A 33KV single core termination.

Nice graphic Tony.

But that looks like the jacket pretermination prep detail not the actual electrical termination... or am I lost here?

Please note, correction. This is a cable joint (splice, inline splice). Similar wiping technique, but NOT a termination. Please do not confuse the two, [although, a joint IS, 2 x termintions, connected together by means of a ferrule rather than 2 x lugs and a bolt(s)].

Amazingly, some folks dont actually know the difference and use the terminology to mean the same thing. Glad you are educated on this. It is has all become 'plug n play' these days.
