What is the construction of the power cord?

Power cord - also known as plug power cord, is a certain length of wire plus a plug or power cord with plugs at both ends. Power cord is small appliances, communications, a variety of mechanical equipment commonly used accessories, simply put, a device or instrument, as long as the need for electricity, are inseparable from the power cord. Power cord is a worldwide product, so we Cixi Baige Electronics Co., Ltd. production of plugs and cords to face the customers is the world, the power cord this product to be exported, you must need product certification, exported to which the power cord must have the appropriate certification. Such as exported to Europe's plug line must have the European VDE certification, exported to the United States of America's power cord must have the United States UL certification, exported to the United Kingdom's power cord must have the British BS certification, exported to Australia's plug line must have the Australian SAA certification ...... power cord since it is a plug plus wire, so that when customers need to must be configured according to the customer's requirements to the corresponding plug and cord. For example, the plug: is a 2-core plug or 3-core plug which plug is needed, how many amperes voltage, how much current; the distribution of the classification of the wire is also a lot of: is a 2-core wire or 3-core wire, different standards and requirements are different, there are different models of wire, such as the European standard H03VVH2-F H05VVH2-F H05VV-F, etc., the size of 2x0.75mm2 2x1.0mm2 3x0.75mm2 3x1.0mm2...... need to match how long the wire. So many specifications and requirements, we must communicate with the customer, and if necessary, we also need to give the customer samples, so that they can confirm. The structure of the power cord has three main parts 1.: the outer sheath, the outer sheath is generally play a protective role, to protect the inner structure is not destroyed, 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 is generally resistant to insulation, high temperature, cold, oil, abrasion, toughness and other characteristics. 2. wire sheath, also known as the insulating sheath, according to the name can be known, the main role is to be used in the use of the outside world, to isolate the object and the direct contact with the current, resulting in the use of the safety. 3. core, core is the core of the power cord is the most important part of the connection between the electrical appliances and the current of the direct contacts The inner core is the core part of the power cord, which is the direct contact between the electrical appliances and the electric current. The material of the inner core is generally copper core, so the good or bad of the copper core directly affects the quality of the power cord.
