The power cord is almost every day can see the ordinary is no longer ordinary things. Speaking of its structure is not very complicated, mainly to the outer sheath, inner sheath, copper composition. But it is not like we have seen so much easier, if you want to study in depth the power cord, then, in some places still need a professional to understand the structure of the power cord. Plug wire
Outer sheath: the outer sheath of said protective sheath, the outermost layer of the sheath of the power cord, this layer of the outer sheath plays the role of the protection of the power cord outer sheath has a strong characteristic, such as high temperature resistance, low temperature, around performance, the high life, carry the natural light interference, materials, environmental protection and other features.
Bedding: Bedding, also known as the insulating sheath, is part of the power cord indispensable intermediate structures, the insulating sheath is the name suggests insulation, to ensure the safety of the power cord of the power, the copper wire and air directly will not produce any leakage phenomenon of insulation materials should be soft to ensure a good set in the middle layer.
Copper: copper wire is the core part of the power cord, copper is the main carrier of current and voltage, the quality of the direct impact of the size of the density of copper wire power cord. Materials is to ensure the quality of the power cord is an important factor, the number of copper wire and Flexibility is one of the main factors to consider the quality of the power cord. |
