ITU-T K.46 (07/2003)

Защита линий связи с симметричными металлическими жилами от электромагнитных волн, индуцированных молнией

Настоящая Рекомендация устанавливает порядок действий по защите линий связи, имеющих металлические симметричные жилы, от перенапряжений и сверхтоков, наведенных в линии при близких разрядах молнии. Порядок действий по защите связан с подверженностью линии воздействиям близких разрядов молнии и включает соединение кабельных оболочек и установку защитных устройств.
