Is shielded twisted pair cable desirable for outdoor installation?

Question

Cables and wires

Will the screen provide lightning protection? Or if there are no power cables nearby, then there is no difference?

Answer 1

The screen is basically a foil winding. She can hold lightning well by herself. You can't ground it properly.
And for the street you need a twisted pair cable for outdoor laying. Do not use the inner one - firstly, the sheath of the internal twisted pair is very easily torn against any sharp corner, is not resistant to tension, and even if everything is laid carefully, the weather, insects, birds and animals will quickly destroy it.

Answer 2

Will the screen provide lightning protection?

Not
Screens still need to be properly grounded. Otherwise, they will be more trouble than good.
Step back from the power cable 20 - 50 centimeters, and that's it.
For laying on the street, a "street" twisted pair is very desirable - in a normal one, after a couple of years, the external insulation will crack, water will begin to collect in it.
