快断和慢断保险丝区别：

 

  1. 快断保险丝：快断保险丝一般型号前F字母开头，例如F1AL250V，多用于电路板，只要电流超过其额定值瞬间即熔断，只能作短路保护
  2. 慢断保险丝：慢断保险丝一般型号前T字母开头，例如T1AL250V，有些电路在开关瞬间的电流大于几倍正常工作电流，尽管这种电流峰值很高，但是它出现的时间很短，我们称它为冲击电流快断的保险丝是承受不了这种电流的，延时保险丝的熔体经特殊加工而成，它具有吸收能量的作用，调整能量吸收量就能使它即可以抗住冲击电流又能对过载提供保护

保险丝的作用：主要是起过流保护作用，如果负载电流太大，超过了保险丝的范围，保险丝就会断开，从而起到保护作用
判别保险丝好坏的方法：保险用万用表电阻档测一下：能通就是好的，不能通就是坏的还有一种是在家里没表的情况下可用下列方法但要注意安全：用电笔放在插座火线上检测是否有电，然后将保险一端放在电笔手按得一端，另一端用手接触；如果保险是好的话这时电笔应亮
注：们在购买保险丝请先查清电路是否还有其他问题，正常情况下，保险丝在电路中起连接电路作用所以换了保险还不能好的也不是保险的问题如果装上保险就烧的，请检查自身电路是否短路

保险丝常识：

  1. 保险丝2头顶铜帽上面有一头是有刻字的，比如F1A250V就表示是1A保险丝，A是电流单位，1A是表示保险丝大承受数值
  2. 长度是20毫米，直径5毫米的就是5×20保险丝长度是30毫米，直径6毫米的是6×30保险丝
  3. 如果不知道要几A保险丝，可以根据自己使用的电器功率计算出来保险丝电流大小，计算方法是电器的瓦数除以电压=电流；可以适当的加大电流；比如500W的电器，电压220V，选择保险丝就500除220=2.27A电流，可以选择2.5A的保险丝

Tips for reducing the shipping cost

1)Get rid of the original packing, for example, if you buy a pair of shoes, you could get rid of the shoebox which will save a lot for volumetric weight.

2)The shipping cost is normally charged by every 0.5KG. So if you buy a product that is only 0.1KG then you might consider buying 2-3 PCS per time which will not add more shipping cost for your order.

Volumetric Weight

Volumetric weight refers to the overall size of a parcel and is measured in volumetric kilograms. Volumetric weight can be calculated by multiplying the length, width, and height of a parcel (in cm) and dividing that figure by 5000 (some carriers use a divisor of 6000/7000 and etc).
