带电作业 绝缘材料梯

[中文适用范围]： 本国际标准适用于带有延伸部分或具有绝缘和导电部分组合的全绝缘拼接梯或钩梯，用于交流或直流电气装置的带电作业，交流电压为 1 000 V 及以上，直流电压为 1 500 V 及以上梯子按功能分为类别 1 和类别 2。本标准仅涉及合成材料制成的梯子。这些梯子通常用于在架空线路结构上提供通道，并促进带电作业，无论是热棒式、徒手式还是两者结合。 [外文原描述]： Is applicable to fully insulating spliced or hook ladders with extension or having a combination of insulating and conductive sections and used for live working on a.c. or d.c. electrical installations at 1 000 V and above for a.c. and 1 500 V and above for d.c. This standard concerns only ladders made of synthetic material. These ladders are used, to provide access, generally on overhead line structures and to facilitate live working, either hot stick, barehanded or a combination of both.
