Hi.
Yesterday I was manipulating cable from an old washing machine to give it a second use.
Between the 3 inner threads (blue, brown and bicolor) there was a kind of white powder.
I would say it was talcum powder or something similar.
The amount was testimonial, but there it was.
What is the function of this white powder?
Maybe it helps to keep the humidity down?
Perhaps it is necessary during the manufacturing process?
