ДСТУ IEC 60502-1:2009
Цей державний стандарт визначає вимоги до конструкції та випробувань силових кабелів з екструдованою ізоляцією на напругу 1 кВ та 3 кВ. Він є основою для забезпечення технічної безпеки та надійності при прокладанні та експлуатації кабельних ліній.
Перевіряйте маркування та паспортні дані кабелів на відповідність вимогам ДСТУ IEC 60502-1 під час вхідного контролю. Враховуйте межі температур нагріву жил при розрахунках захисту від короткого замикання.
