What I forgot to comment is that you should notify the consortium about this intervention since some goalkeepers will not work while you work.

Okay. What I did not understand is the "With small sections of insulation of the same cable you isolate them"

Hi. First you must request authorization from the consortium and if they authorize you you must place two boxes, one upper and one lower. Remember that they are common lines to other units. They do not weld, they curl and it is isolated with "spaghetti" Greetings

I do it with multipair cable?

Indeed, you must use the same doorman-type cable that they have placed. With that of the insulator, only sections of the cable lining of a pair are usually placed as a cap.

Ok servimat. From what I see the ones that go up are all red wires. They must be old by the age of the building. I buy a multipair cable for porter. Any measure? Why didn't I get them and buy a multipair that comes 4 pairs + neutral ... walk?

How many cables do you have now to extend?

Yes, with 4 pairs it will work well, there are 8 in total. The earth tries to connect it to the pipe (if it is metallic) to give it electrical continuity if they have used it as a shield.

The internal wire is only to peel the sheath, it has nothing to do with the earth of the pipes since it is low voltage and audio, in any case there are meshed cables to avoid interference or wrapped in aluminum foil.
