What are the materials of communication cables?
Tensile components: typical structure, steel core aluminum stranded wire, fiber optic cable, cable and so on, the whole near special, thin and flexible, requiring bending and distortion, the use of tensile components play a major role
A sense of wire and cable manufacturing industry material finishing assembly industry materials giant cable products accounted for the total cost of materials to manufacture 80-90%; performance requirements are particularly high for Copper Conductor Copper purity to 99.95% products to high pure copper by oxygen two material categories, three varieties; material selection, manufacturing process, product performance and service life the decisive effectThe benefits of wire and cable manufacturing enterprises are closely related to material selection, processing and production management, and materials savingThe design of wire and cable products must be carried out in the same way as the selection of materials. Several materials are selected for the process and performance screening testsCable products with materials according to their position and function, conductive materials, insulation materials, filling materials, shielding materials, protective layer material etc. the material a few general structure especially thermoplastic polyvinyl chloride, polyethylene and other department to change with the insulation or sheathCable products manufacturing materials used in various categories, specifications (brands) in particular
The vast number of wire and cable products section (cross section) have identical shapes (ignoring the manufacturing error), strip products due to system or equipment for the line or coil characteristics determined by analysis of product structure for the cable group cross section observation analysisWire and cable products, structural components, overall wire, insulation layer, shielding layer four, the main structure of the group and filling components, components and so on, according to product requirements, application occasions, product structure is very simple
