The structure of the power cord is not very complicated, but not from the surface to be at once simple to see through it, good to study if the power cord, then in some places still need a professional to understand the structure of the power cord.
The structure of the power cord to the outer jacket, inner jacket, copper wire.
Outer sheath: the outer jacket is also known as protection sheath is the outermost layer of the power cord sheath, the protective outer sheath plays the role of the power cord, outer sheath has a powerful feature, such as high temperature , Low temperature, carry natural light interference around the degree of performance, high service life, materials, environmental protection and other features.
Bedding: Bedding is also known as insulated jacket is a power line in the middle of the structure indispensable part of the main sheath is insulated with the name implies, to ensure the safety power cord, so that copper and air is not directly Any leakage phenomenon, and the sheath material should be soft, guarantee a very good set in the middle layer.
Copper: Copper is a core part of the power cord, copper wire mainly current and voltage of the carrier, the density of copper wire the size of a direct impact on the quality of the power cord. Power cord to ensure the quality of materials is an important factor, the number of copper wire and Flexibility is one of the factors taken into account |
