FLGOEU is the cable that nobody thinks about until it fails—and when it fails, everything stops. It is a 300/500 V self-supporting lift and pendant control cable engineered by Anhui Feichun Special Cable Co., Ltd. per VDE 0250 for the quiet, essential applications that keep industrial equipment running: the control cable hanging inside an elevator shaft that carries floor-call signals, door-open commands, and safety interlock data between the car and the controller; the pendant cable dangling from an overhead crane that lets the operator control hoist, traverse, and bridge movements with pushbuttons; the control cable suspended from a conveyor structure that feeds sensor and actuator signals to the drive system; and the pendant cord on a construction machine that connects the remote-control station to the machine's hydraulic valves.

Российская марка КПГ-ХЛ может быть сбивающей с толку, потому что в разных источниках её описывают по-разному. На самом деле в России существует три разных плоских кабеля для гибких приложений, и их часто путают: КГЭ-ХЛ (горный кабель гибкий экранированный) — в основном круглый профиль, диаметр 60–75мм для сечений 95–150мм². Используется для буровых и экскаваторных приложений (см. нашу предыдущую статью о сибирских рудниках). КПГ-ХЛ (кабель плоский гибкий холодостойкий) — истинно плоский профиль с сечением примерно 12–30мм толщины и 200–400мм ширины в зависимости от количества проводников и их сечения. Это кабель для портальных кранов, мостовых кранов и фестун-систем. КПГП-ХЛ (кабель плоский гибкий полиэтиленовый холодостойкий) — плоский профиль с полиэтиленовой изоляцией (вместо HEPR), обычно меньшего сечения, 2.5–6мм². Немецкий NGFLGÖU-J по VDE 0250-809 — это истинно плоский гибкий кабель для скользящего контакта в фестун-системах промышленных кранов. По функциональности и форме он почти идентичен КПГ-ХЛ, но с критической разницей в материалах оболочки.
