Crimped copper pipe filled with grease from a stepdown transformer

[Rob Brooks]

Hi. I'm 16 and studying electrical installations L2 at college. The stepdown transformers near my house recently got changed for new ones and I found a short piece of thick walled copper pipe underneath where the transformer is. The copper pipe has a relatively thick wall, filled with grease, has two plastic end caps, a crimped section in the middle and some markings. The markings say:

CF032
32°HD Cu
DIE 9997/IND 163

Can anyone tell me what it is and what is it used for? Ill attach some pictures.

Thanks,

Rob

Looks like a compression splice for jointing bare overhead lines.

Quite likely. The grease will be to displace water and reduce corrosion inside the crimp.

Bet he will keep that forever

I'd've been hassling them to give me the old transformer.

HV experiments to be done

It's a crimp as suggested above, used with a hydraulic crimper, the markings are to make sure you use the correct die. Takes me back a few years as I used to use similar when I was a leccy board cable jointing apprentice about 30 years ago, did a few months familiarity on overhead lines and realized that I didn't like heights!!

rolyberkin, how old are you man? I had you down as a youngster! I guess I was trying not to get out off by the margarine trombonist!

A young 47! Am a returning to the fold spark after being involved in other things for a few years, the Lurpak trombone man is a reference to me playing trombone in a ska band!
