Overview | 概述 | Обзор
Кабели марки КОГРВЭШ предназначены для присоединения шахтного бурильного электроинструмента на номинальное переменное напряжение 660В частоты 50 Гц с изолированной нейтралью.
Кабели могут эксплуатироваться в подземных помещениях и шахтах с повышенной влажностью воздуха, в которых возможно длительное наличие воды или частая конденсация влаги.
Электропроводящие экраны по изоляции жил обеспечивают опережающее отключение системы электроснабжения при повреждении кабеля, предупреждая возможный взрыв метана в шахтах.
КОГРВЭШ系列電纜專用於連接礦用鑽機電動工具，額定交流電壓660V，頻率50Hz，採用隔離中性點系統。
電纜可在高濕度的地下空間和礦井中使用，適用於長期有水或頻繁結露的環境條件。
芯線絕緣層上的導電屏蔽可在電纜損壞時實現供電系統的提前斷電，從而預防礦井中可能發生的甲烷爆炸。
KOGRVESH cables are designed for connecting mining drilling electric tools at rated AC voltage of 660V, 50Hz frequency, with isolated neutral system.
The cables can be operated in underground spaces and mines with elevated air humidity, where prolonged water presence or frequent moisture condensation is possible.
Conductive screens over core insulation ensure early disconnection of the power supply system when the cable is damaged, thereby preventing possible methane explosions in mines.
