Description
A power cable is a cable that carries electrical current, the current is usually transmitted point-to-point. Power cable can be divided into AC power cable and DC power cable, usually the AC power cable is a wire with a high voltage of alternating current, such wire can be officially produced due to the high voltage needs to obtain a unified standard safety certification party. The structure of the power line mainly requires outer sheath, inner sheath and conductor， the common transmission conductor is copper, aluminum metal wire and so on.
The outer sheath, also known as the protective sheath, is the outermost layer of the power line sheath, this layer of outer sheath plays the role of protecting the power cable, the outer sheath has powerful characteristics, such as high temperature resistance, low temperature resistance, resistance to natural light interference, good winding performance, high service life, material environmental protection and other characteristics. The inner sheath, also known as the insulation sheath, is an indispensable part of the middle structure of the power cable. The main use of the insulation sheath, as the name suggests, is insulation to ensure the safety of the power line, so that there will be no leakage between the copper wire and the air, and the material of the insulation sheath should be soft to ensure that it can be well inserted in the middle layer. Copper wire is the core part of the power cable, copper wire is mainly the carrier of current and voltage, the density of copper wire directly affects the quality of the power line. The material of the power cable is also an important factor in quality control, and the quantity and flexibility of the copper wire are also one of the factors to be considered.
