Провода самонесущие изолированные и защищенные (СИП)

Провода самонесущие изолированные и защищенные (СИП)

Короткая черта

Самонесущий изолированный провод (СИП), рассчитанный на номинальное напряжение 660 и 1000 В частотой до 50 Гц, служит для передачи электроэнергии в воздушных линиях электропередачи и ответвлений ко вводам в жилые дома и хозяйственные постройки.

Конструкция кабеля

Вокруг нулевой несущей жилы, выполненной из дюралевого сплава, скручены изолированные фазные токопроводящие жилы из дюралевого либо сталеалюминиевого сплава. Жилы многопроволочные, уплотнённые. Изоляция сделана из термопластичного светостабилизированного сшитого целофана.

Технические и эксплуатационные свойства

СИП предназначен для эксплуатации при температуре от -50°С до +50°С и относительной влажности воздуха до 98% (при температуре +35°С). Предельная продолжительно допустимая температура нагрева жил кабеля в рабочем режиме составляет + 90°С, в аварийном режиме либо в режиме перегрузки + 130°С (при продолжительности нагрева менее 8 часов в день и 1000 часов за весь срок службы). При маленьком замыкании (до 4 сек) наибольшая допустимая температура нагрева жил 250°С.

Изолированные жилы проводов выдерживают испытание переменным напряжением 3,5 кВ частотой 50 Гц на проход. После выдержки в воде при температуре 10-30°С провода
Наименее 10 мин должны выдерживать испытание переменным напряжением 2,5 кВ (для марок СИП-1 и СИП-1А) и 4 кВ (для марок СИП-2 и СИП-2А). Провода СИП выдерживают испытание переменным напряжением 4 кВ частотой 50 Гц в течение 1 часа.

Прокладка и установка кабелей СИП без подготовительного нагрева может выполняться при температуре не ниже -20°С. Малый радиус извива при прокладке - 7,5 Dн (Dн - внешний поперечник кабеля). Провод обладает стойкостью к солнечной радиации.

Строительная длина СИП согласовывается при заказе. Гарантийный срок эксплуатации кабеля – 3 года, срок службы - 40 лет.

Достоинства проводов СИП

Провода СИП обеспечивают бесперебойную подачу электроэнергии, владеют высочайшей прочностью, стойкостью к механическим повреждениям, работают даже в сложных погодных и брутальных хим критериях. Кабели подразумевают установка без отключения полосы, возможность совместной подвески на опорах проводов с различным уровнем напряжения и с телефонными линиями, возможность монтажа ЛЭП по фасадам построек – без установки излишних опор, загромождающих тротуары городка.

Благодаря маленькому реактивному сопротивлению, кабели СИП позволяют существенно понизить энергопотери. Необходимыми преимуществами являются высочайшая безопасность обслуживания и отсутствие риска поражения при касании фазных проводов, находящихся под напряжением, также безопасность работ в конкретной близости от ЛЭП.

Сфера внедрения

СИП интенсивно используются при разработке ответвлений ко вводам построек и зданий жилого и хозяйственного предназначения, также проведении магистральных воздушных линий электропередач. При прокладке проводов СИП в пожароопасных зонах на изоляцию наносят особое покрытие, придающее кабелям огнестойкость и являющееся дополнительной защитой от пожара.
