小编说的就是一款环保阻燃电缆，下面让我们一起来进入正文。 With the development of science and technology and people's emphasis on environmental protection awareness, people's environmental protection requirements for cables are getting higher and higher. Today Xutong editor is talking about an environmentally friendly flame retardant cable. Let us enter the text together.
The structural elements of wire and cable products can be divided into four main structural components: conductors, insulation layers, shields and sheaths, as well as filler components and tensile components. Depending on the requirements and applications of the product, some product structures are extremely simple.
In a sense, the wire and cable manufacturing industry is a material finishing and assembly industry. First, the amount of material is huge, and the material cost in cable products accounts for 80-90% of the total manufacturing cost. Second, the types and types of materials used are very large, and the performance requirements are particularly high. For copper for conductors, the purity of copper is required. Above 99.95%, some products need to use oxygen-free high-purity copper; third, the choice of materials will have a decisive influence on the manufacturing process, product performance and service life.
At the same time, the benefits of wire and cable manufacturing companies are also closely related to whether materials can be scientifically saved in the selection, processing and production management of materials.
Therefore, the design of wire and cable products must be carried out simultaneously with the selection of materials. Generally, several materials are selected and determined after screening tests of processes and performance.
The materials for cable products can be divided into conductive materials, insulating materials, filling materials, shielding materials, and sheathing materials according to their use parts and functions. But some of these materials are common to several structural parts. In particular, thermoplastic materials, such as polyvinyl chloride, polyethylene, etc. can be used on insulation or sheath as long as some of the formula ingredients are changed. The materials used in the manufacture of cable products involve a wide range of categories, with many varieties and specifications (brands).
