power cord-also known as plug power cord, is a certain length of wire plus a plug or two power cords Both ends have plugs. The power cord is a commonly used accessory for small appliances, communications, and various mechanical equipment. Simply put, a device or instrument can be used as long as it needs power. The power cord is a product all over the world, so our plug cords produced by Cixi Baige Electronics Co., Ltd. are facing customers all over the world. If you want to export the power cord, you must require product certification and export to which country. The power cord must be certified accordingly. If the plug cable exported to Europe must have European VDE certification, the power cord exported to the United States must have American UL certification, the power cord exported to the United Kingdom must have British BS certification, and the plug cable exported to Australia must have Australian SAA certification...
Since the power cord is a plug plus a wire, so the customer must configure the corresponding plug and wire according to the customer's requirements. For example, the plug: is it a 2-core plug or a 3-core plug? Which country's plug is required, how much ampere voltage and current? There are many classifications of distribution lines: whether it is a 2-core wire or a 3-core wire. The standards and requirements of different countries are all There are different types of wires, such as the European standard H03VVH2-F H05VVH2-F H05VV-F, etc. The size is also 2x0.75mm2 2x1.0mm2 3x0.75mm2 3x1.0mm2...... How long the wire needs to be equipped. With so many specifications and requirements, you must communicate well with your customers. When necessary, you need to give customers samples for confirmation.
So what is the structure of the power cord? There are three main parts of the power cord structure
The first part: outer sheath, the outer sheath generally plays a protective role, protecting the inner structure from being damaged, so that the power cord can be used normally and safely. The outer sheath is in direct contact with the outside world, so the outer sheath generally has the characteristics of insulation resistance, high temperature resistance, cold resistance, oil resistance, wear resistance, toughness and so on.
The second part: the wire sheath is also called the insulating sheath. According to the name, it can be known that the main role is to isolate the external objects from direct contact with the current during use, resulting in safety in use.
The third part: the inner core, the inner core is the most core part of the power cord, is the direct contactor connecting the electrical appliance and the current, and is the medium between the electrical current and the electrical appliance. The material of the inner core is generally a copper core, so the quality of the copper core directly affects the quality of the power cord
