这种插线板早已被禁用！家里有的尽快扔掉

你家是否还在用图中的这种万能插线板——在同一个插位，既可以插两极插头，又可以插三极插头的万用型插座。如果有，建议尽快更换！

这种万能插线板为了兼容各种插头，设计上存在致命缺陷——插片与电器插头接触面积小，容易产生电弧和高温，其引发火灾的风险是普通插线板的数倍。2010年6月起，这种插线板就被禁止生产了。

Power strips, which allow both two-prong and three-prong plugs to be inserted into the same socket, contain a critical design flaw in their attempt to accommodate various plug types. The smaller contact surface between the metal connectors and appliance plugs can easily lead to electrical arcing and overheating, making them several times more likely to cause a fire compared to standard power strips. These products have been banned from production since June 2010.

万能插线板已经被淘汰

据消防部门的调查显示，由插线板短路导致的火灾往往源于几个常见错误：使用老化的“高龄”插线板、多个大功率电器共用一个插线板、继续使用国家早已明令禁止的“万能插线板”。

According to a fire department investigation, fires caused by short circuits in power strips often stem from several common mistakes: using aging or outdated power strips, overloading a single power strip with multiple high-wattage appliances, and continuing to use universal power strips that have been banned by national regulations.

国网浙江电力高级专家徐家宁表示，这些错误行为中，最危险的当属已经被国家明令禁止的“万能插线板”。

插线板的3个错误用法

除了万能插线板，插线板在使用时还有3个安全隐患：

• 超负荷使用

市面上常见的家用插线板，额定电流通常为6安（A）、10安（A）和16安（A）。

如果同时接入多个大功率电器，比如将电热水壶（1500瓦）和微波炉（1000瓦）插在同一个10安（A）的插线板上，总功率就会超过插线板2200瓦的承载极限，若同时开启就会导致过热甚至起火。

Household power strips (common specifications: 6A, 10A, 16A) have strict power limits. For example, a 10A power strip has a maximum load capacity of 2,200 watts. If multiple high-wattage appliances such as a 1,500W electric kettle and a 1,000W microwave are used simultaneously, the total power consumption will far exceed the strip's limit, which can lead to overheating and cause a fire.

• 使用劣质产品

一些不良商家为了降低成本，采用非阻燃材料制作外壳，或者用导电性能差的铝代替铜作为导线，这样的插线板一旦遇到高负载，极易短路起火。

Some unscrupulous manufacturers use non-flame-retardant materials for the casing or replace copper with poorly conductive aluminum for internal wiring in order to cut costs. Such substandard power strips are highly prone to short circuits and can ignite fires when under high loads.

• 忽视使用寿命

插线板一般使用3~5年就需要更换，如果出现插孔发黑、插头松动等情况，说明它已经“超期服役”，必须立即淘汰。

It's important to replace power strips regularly — typically every three to five years. If you notice discolored sockets or loose plugs, it's a clear sign that the power strip has aged and should be replaced immediately.

4个习惯，让用电更安全

要确保用电安全，必须要养成几个关键习惯。这些看似简单的措施，很可能是避免一场灾难的关键。

• 大功率电器“专插专用”

家中的插座不要同时使用超过额定功率的电器，大功率电器（如空调、冰箱、电热水器等）一定要单独使用专用的插线板。

Do not overload household outlets with appliances exceeding their rated power. High-wattage appliances such as air conditioners, refrigerators, and water heaters should always be plugged into a separate outlet.

• 电器不用时要拔插头

电器关闭后，插头要是没拔掉，电表也是会走字的。长期不用的电器要及时拔掉插头，避免电路持续带电。

如果担心反复拔插头会坏，可换成带开关的插座面板。这样除了节省电费，还能减少不拔插头带来的火灾隐患。

Even when turned off, appliances continue to consume standby power if left plugged in. It is recommended to promptly unplug devices not in use for extended periods or switch to outlets with switches. This helps save electricity and reduce fire risks.

• 拔插头尽量用双手

拔插头时切记要握住插头而非拉扯电线，尽量双手操作，一手固定插座，一手插拔插头，避免插拔插头时发生晃动，产生电火花。注意要保证手部干燥。

When unplugging, always grasp the plug firmly instead of pulling the cord. Operate it steadily with both hands — stabilize the outlet with one hand while plugging or unplugging with the other to avoid sparking caused by movement. Also, ensure your hands are dry.

• 插线板老化立即更换

发现插线板温度异常或是插孔变色，需要立即停止使用。发现插线板老化，即使更换，严禁自行改造电器插头。

If a power strip is found overheating or has discolored outlets, stop using it immediately. Replace it promptly if aging is observed, and never attempt to modify the plug by yourself.
