Generally speaking, AC power lines are wires produced through high-voltage AC power lines. Due to the high voltage, safety certification personnel can officially produce. DC lines basically pass through low-voltage DC, so AC lines are not strictly secure. However, due to security reasons, countries require unified security certification.
What is the structure of the industrial camera power cable network?
The structure of the industrial camera power cord network cable is not complex, but it is not easily visible on the surface. To study power cords well, there are some areas where it is necessary to understand the structure of power cords.
The structure of industrial camera power cable network mainly includes outer sheath, inner sheath, conductor, copper, aluminum wire, and other typical transmission conductors.
External materials
The sheath, also known as a protective film, is the sheath outside the power cord, with strong characteristics such as high temperature resistance, low temperature resistance, resistance to natural light interference, bypass performance, service life, and material environment.
Internal protective layer
The inner and outer length, also known as the insulating sheath, is an indispensable part of the intermediate structure of the power cord. As the name implies, the main purpose of insulating sheath is insulation. In order to ensure the electrical safety of power lines and prevent leakage between copper and air, the insulating sheath material should be soft and well embedded in the intermediate layer.
copper
Copper wire is the core part of the power cord. Copper wire is mainly the carrier of current and voltage. The density of copper wires directly affects the quality of power cords. The material of the power cord is also an important factor in quality inspection, and the quantity and flexibility of the copper wire are also factors that need to be considered.
Internal protective layer
The material used to wrap the inner sheath between the shielding layer and the core layer is usually polyvinyl chloride plastic or polyethylene plastic. There are also low smoke halogen-free materials. According to the process regulations, ensure that the insulation material does not come into contact with water, air, or other objects to prevent mechanical damage to the insulation moisture and insulation material.
