越“利落”可能越危险？这个“好习惯”，建议你改掉

Core Viewpoint - The article emphasizes the dangers of using power strips and the risks associated with improper management of electrical wires, particularly when multiple high-power devices are connected simultaneously. Group 1: Experiment Findings - In the first experiment, an 1800-watt electric kettle was monitored, and the wire temperature reached 19.8℃ after the kettle turned off automatically [1][5]. - In the second experiment, four identical electric kettles were connected to the same power strip, leading to smoke emission as the temperature rose [3][5]. - The temperature peaked at 217.2℃, causing the bundled wires to make a loud noise and resulting in insulation damage and exposed wires [4][5]. Group 2: Safety Guidelines - Using universal power strips has been banned since June 2010 due to their increased risk of fire from poor contact area with plugs [7]. - Connecting multiple power strips in series can lead to overload, poor contact, and unstable voltage, posing several risks [9]. - Low-quality products made from non-flame-retardant materials or using aluminum instead of copper for wiring can easily short-circuit under high load [11]. - Power strips should be replaced every 3-5 years, and signs of wear such as blackened sockets or loose plugs indicate the need for immediate replacement [11]. Group 3: Recommendations - It is advised to use power strips with "3C certification" and select appropriate lengths based on the usage environment [13]. - Bundling electrical wires is discouraged, and high-power devices should be used with dedicated outlets [14]. - Unplugging devices when not in use and promptly replacing aging power strips are recommended for safety [14].
