Drawing, Sfs Insulation Tandem Line

Nowadays, the world has already entered the information society. LAN, the basic unit of high-speed information network, its transmission rate is getting faster with the development of society.
The data cable is one of the most important transmission media of the LAN, and the development of the LAN is also driving the rapid growth of the data cable. In the future for a long time, data cables will be used widely .
In order to meet the high-speed information transmission requirements of today's social networks, data cables have evolved from the lower transmission rates like Cat.3, Cat.5e, and Cat.6 to higher transmission rates of Cat.6A, Cat.7, and Cat. 7A and even the highest category Cat.8.
With the development of communication networks, Cat.6A and higher categories of data cables have become the mainstream products of network wiring systems. In order to achieve better transmission performance, such data cables no longer use traditional solid insulation, but must use foam insulation type. In order to ensure that the insulated wire core reaches a highly precise geometric size and the best quality. At present, the extrusion of Cat.6A and above categories adopts a drawing skin-foam-skin insulation tandem extrusion production line.
Insulation extrusion is the most critical production process for data cables. The quality of the insulation is directly related to the performance indicators of the entire data cable product. Our company has many years of experience in research and development and manufacturing of data cable production equipment. Our drawing-skin foam skin insulation tandem extrusion production line has many core technologies, which are suitable for Cat.6A, Cat.7, Cat.7A, Cat.8 production of foam insulation. The test performance of the finished cable products can meet the requirements of ISO 11801, IEC 61156, ANSI / TIA 568 and other standards.
