【Daily Question 22】June 22, 2018

A. Insulating rod D. Insulating clamps The focus of this question is knowledge related to electrical safety equipment. Electrical safety equipment are specialized tools and devices used by electricians to prevent dangers such as electric shock, falls, and burns, thereby ensuring the safety of workers. These include insulating safety equipment that serves to provide insulation as well as for testing and measuring voltage, safety equipment for working at heights, as well as maintenance safety equipment such as temporary grounding wires, barriers, and warning signs used during maintenance work. Insulation safety equipment includes insulating rods, insulating pliers, insulating boots, insulating gloves, insulating mats, and insulating platforms. Insulation safety equipment is divided into basic safety equipment and auxiliary safety equipment. The former has an insulation strength that can withstand the operating voltage of electrical equipment for a long time, allowing it to be used directly to operate such equipment ； The insulation strength of the latter is not sufficient to withstand the operating voltage of electrical equipment; it can only enhance the function of basic safety equipment. Insulated rods and insulating clamps are considered basic safety equipment, while insulating boots, insulating gloves, insulating mats, and insulating platforms are classified as auxiliary safety equipment. Therefore, options AD are correct.
