Due to the use of cables in different conditions, the requirements for different properties of these cables are justifiably indicated. And in each individual case it is necessary to look for different conditions and options in order to make the network relatively inexpensive, functional reliable.

But at the same time, it will achieve reliable and uninterrupted energy supply.
