An Intrinsically Safe network consists of a number of cells.The Intrinsically Safe design of the network requires each cell to be individually powered and that electrical power must not travel between them. Cells can be connected in a loop configuration to provide multiple redundant network paths to the surface.

Буду благодарна за комментарии по поводу следующих моментов:

loop configuration - петлевая конфигурация
multiple redundant network paths - несколько резервированных сетевых путей
Cell - ячейка
