In a sense, wire and cable manufacturing industry is a finishing and assembly of materials industry. First, the huge amount of materials, cable products in the cost of materials to the total cost of manufacturing 60-90%;
At the same time, the benefits of cable manufacturing enterprises and materials selection, processing and production management can be scientifically saved materials are closely related.
Therefore, in the design of wire and cable products must be used with the selection of materials at the same time, the general use of several materials, through the process and performance screening test to determine.
2, cable products with the use of materials and functions, can be divided into conductive materials, insulation materials, protective materials, shielding materials, fill materials. But some of these materials are common to several structural parts, such as shielded copper wire, copper tape is also a conductor with electric copper.
Especially thermoplastic materials, such as polyvinyl chloride, polyethylene and so on as long as the change part of the ingredients can be used in the insulation or jacket.
