RG6 cable structure name and material
Wire: the product of the current or electromagnetic wave information transmission function of the most basic essential components.
The main material: wire is the short name of the conductive wire, with copper, aluminum, copper clad steel, copper clad aluminum and other conductive properties of non-ferrous metals made of light to fiber as a wire.
There are bare copper wire, tinned wire; single line, stranded wire;
Insulation: is covered in the wire around the periphery of the electrical insulation of the components. That is, to ensure that the transmission of current or electromagnetic waves, light waves along the wire without flowing to the outside, the conductor has a potential (that is, the potential difference between the surrounding objects, that is, voltage) can be isolated, that is, to ensure the normal transmission of the wire Function, but also to ensure that external objects and personal safety. Wires and insulation are two basic components that must be made to form a RG6 cable product (except for bare wires).
Main materials: PVC, PE, XLPE, polypropylene PP, fluorine plastic F, rubber, paper, mica tape
Filling structure: a lot of wire and RG6 cable products are multi-core, these insulated wire or wire pairs into the cable (or group into a number of cable), the first shape is not round, the second is a large gap between the insulation core , It must be in the cable when the filling structure, filling structure is to make the cable diameter is relatively round to facilitate the band, squeeze jacket.
Main material: PP rope
Shield is a component that isolates the electromagnetic field from the RG6 cable product from the electromagnetic field of the outside. Some RG6 cable products also need to be isolated from each other within different pairs (or groups). It can be said that the shield is an "electromagnetic isolation screen". High-voltage cable conductor shielding and insulation shielding is to homogenize the distribution of electric field.
Main materials: bare copper wire, copper clad steel wire, tinned copper wire
Cover: When the wire and RG6 cable products installed in a variety of different environments, must have a whole product, especially on the insulation layer of the protective component, which is the sheath.
Because of the requirements of insulating materials with excellent electrical insulation properties, you must require the material of high purity, impurity content is extremely small; often can not take into account its external protection, so for the outside world (that is, the installation, use and use of the ) Various mechanical forces to bear or resistance, resistance to atmospheric environment, chemical resistance or oil, the prevention of biological damage, and reduce the risk of fire and so must be borne by a variety of protective structure.
Main materials: PVC, PE, rubber, aluminum, steel
Tensile components: the typical structure is steel core aluminum wire, fiber optic RG6 cable and so on. In short, the development of special small, soft type, while requiring multiple bending, twisting the use of the product, the tensile element plays a major role.
