How much do you know about the purchase of a flexible cable, do we know how to choose these materials? Flexible cable is the time when we are building materials decoration. When installed in the dark of the flexible cable the choice is to take. Quality is a part of the need to pass. This is related to the future life of the comfort and the owner's life security. It is very important to understand the structure of flexible cable. After being familiar with its properties and structure, it will be more satisfactory to buy.
Wireway
The wire is the most basic and essential component of the product or the electromagnetic wave information transmission function.
Main material: wire is referred to as the conductive wire core, excellent conductive properties of copper, aluminum, copper clad steel, copper clad aluminum, nonferrous metal is made of optical fiber as a conductor.
Insulating layer
The insulation layer is a component that is coated in the outer periphery of the conductor. Can ensure the transmission current or electromagnetic waves, light only marching down the wire and do not flow to the outside, the conductor has the potential (of objects surrounding the formation of potential difference, namely voltage) to be isolated. It is necessary to guarantee the wire's normal transmission function, but also to ensure external objects and personal safety. Conductors and insulating layers are two basic elements that constitute the cable products (except the bare wire).
Main materials: PVC, PE, XLPE, PP, F, rubber, paper, mica tape.
Filling structure
A lot of flexible cable products is a multi-core, these insulated wires or cable to cable group (or multiple cables), one is the shape of roundness, second is the insulated gap reserved between the core wire. Therefore, it is necessary to in cable when adding filling structure, filling structure is to enable cable diameter were relatively round whole in order to facilitate the bag belt, extrusion sheath.
Main material: PP rope
Shield
The shield is a will be the electromagnetic field of the electromagnetic field and outside the cable products were isolated components; by cable products in the different line (or lines) between also need to isolate from each other. It can be said that the shield is a kind of electromagnetic shielding". The conductor shielding and insulation shielding of high voltage cables are the distribution of the electric field.
Main material: bare copper wire, copper clad steel wire, tin copper wire
Protective layer
When the flexible cable products are installed in a variety of different environments, it is necessary to have a protective effect on the product whole, especially for the insulation layer. Because the requirements of insulating material have excellent electrical insulation properties. It is required that the materials of high purity and impurity content are minimal; often fail to take into account the protection of the outside world, so for the outside world, installation, use situation and a variety of mechanical bear or resistance, resistance to atmospheric environment, chemical or oil, to biological invasion prevent and reduce fire hazards must be by a variety of protective layer structure to bear.
Main materials: PVC, PE, rubber, aluminum, steel tape
Tensile element
A typical structure is steel core aluminum, fiber optic cable, etc. In short, in the development of special fine, soft, and at the same time, requirements of multiple bending, and twisting the use of products, the tensile component plays a major role.
