Конструкция.

Провода состоят из алюминиевых проволок, скрученных правильной скруткой с направлением скрутки соседних повивов в противоположные стороны, причем наружный повив имеет правое направление скрутки.
Применение.

Провода неизолированные марки А предназначены для передачи электрической энергии в воздушных электрических сетях, в атмосфере воздуха типов I и II при условии содержания в атмосфере сернистого газа не более 150 мг/м² сут. (1.5 мг/м³) на суше всех макроклиматических районов по ГОСТ 15150 исполнения УХЛ, кроме ТВ и ТС.
Технические характеристики.

Длительнодопустимая температура проводов при эксплуатации, не более +90°С.
Гарантийный срок эксплуатации 4 года с момента ввода проводов в эксплуатацию.
Срок службы проводов, не менее 45 лет.

Число проволок в проводе, их номинальный диаметр, число повивов и строительная длина проводов марки А представлены в таблице:
