Fracture resistance and flame resistance data cable

Abstract

The invention discloses a fracture resistance and flame resistance data cable, and belongs to the technical field of digital communication cables. An insulating layer extrudes the outside of the conductor so as to form a lead. Each two leads are twisted so as to form a pair lead. A number of 2-4 pair leads centers around a reinforcement member made of a circle polyolefin elastomer and twists so asto form a cable core which as a circle cross section. The cable core is successively wrapped with a composite belting from the internal to the external on the outside thereof and extrudes an inner sheath layer and an outer sheath layer. According to the invention, the insulating layer and the sheath layer use a low smoke and halogen free flame resistance polyolefin material and uses a heat insulation non-woven fabric as a belting layer, thus increasing the flame resistance characteristics of the cable; the reinforcement in the center uses a soft elastic material, which increases the mechanical performance as well as the flexible performance of the cable and can prevent adverse influence caused by the bending that is generated in the construction of the cable. According to the invention, the fracture resistance and flame resistance data cable is applicable to data transmission engineering in the field of communication.

Description

Technical field [0001] The invention belongs to the technical field of communication cables, and particularly relates to a flexural flame-retardant data cable. Background technique [0002] With the development of society, there are more and more electrical facilities in high-rise buildings, public venues, and smart office places, and the number of short-circuit fire accidents caused by aging cables is increasing. Therefore, people have higher and higher requirements for cable fire protection. At the same time, the advent of the big data era puts forward higher requirements for the transmission quality of data cables. However, the current data cable is easy to cause discounts during the construction and laying-out process, which affects the transmission quality. In addition, the flame retardant performance is low, and a large amount of toxic smoke is emitted during combustion, which is not conducive to the evacuation of personnel and the progress of fire extinguishing projects. ...
