The basic structure of the industrial bus cable generally has conductor, insulation layer and outer sheath, the conductor is used to conduct current, mainly divided into solid and twisted two, conductor made of aluminum, copper and so on.
In general, the conductivity of copper is relatively much better, the utilization rate is relatively high; insulation is covered in the conductor, used to isolate the conductor, and bear the corresponding voltage to prevent leakage of current to ensure the safety of work, insulation The production of materials is also diverse, but the insulation performance must be good, or not the role of insulation;
The outer layer is the most important part of the cable that plays a protective role. The materials are mainly made of rubber, plastic and metal. The plastic is often used.
In addition to these basic structures, but also according to the demand to add some other structure, such as shielding and inner layer. The shield is in the outer and outer layers of the insulating layer, and its function is to limit the electric field from electromagnetic interference.
