Electric wire and cable products structure:
Electric wire and cable products structure and, in general, could be divided into conductor, insulating layer, shielding and security layer the four structure component.
Conductor is play the use function of the product, is the main structural component of passing information transmission power or, or in the conductor to through the current or conduction electromagnetic waves.
Global trade nets insulating layer is in the outer conductor plays the role of insulation components. That is the current or electromagnetic wave ensure transmission only along a conductor go to outside, the conductor of the potential (has to form around objects, namely the voltage potential difference) can be cut off. So insulating layer is to guarantee the normal transmission function and ensure conductor external objects and the personal safety of the important components.
Security layer is especially for insulation to product whole protection to the component, wire and cable is properly in various external environment condition for a normal work guarantee components.
Shielding is a will cable products in the electromagnetic field and external electromagnetic fields in isolation of structures; and Some cable products in its internal line on the different between also need to mutual isolation.
