Hi folks,

We are facing some problems with electrical connections in our old system (more than 50 years old) due to short circuits.

Our cables are all made of aluminiun (from 266 to 945 MCM, ACSR) and the majority of our connection are Al-Al. Also we have Al-Cu.

I would appreciate if somebody could give me some tips to understand better what is happens and also how to cope with this old problem.

We use only bolted connectors. Someone has suggested to use connectors type "ampact". Tips are welcoming!

Best regards,
