适用于在额定电压超过1 kV r.m.s.的工频下带电作业的带有液压工具和设备配件的移动绝缘软管。 带有配件的绝缘软管用于在液压工具和处于不同电位的泵之间提供连接。它们不被视为带电工作装置（如高空作业装置）的固定部件。它们可以在可忽略的压力下连接和断开。它们可以由用户直接处理。

Is applicable to mobile insulating hoses with fittings used with hydraulic tools and equipment for live working at nominal voltages exceeding 1 kV r.m.s. at power frequency. Insulating hoses with fittings are used to provide a connection between the hydraulic tool and the pump which are at different potentials. They are not considered as a fixed component of a live working device (e.g. aerial device). They can be connected and disconnected under negligible pressure. They can be directly handled by the user.
