Abstract
The invention discloses a network cable which comprises four twisted pairs, a metal tape wrapping shielding layer arranged outside the four twisted pairs, and an outer sheath layer arranged outside the metal tape wrapping shielding layer, wherein a flame-retardant filling layer is arranged between the four twisted pairs and the metal tape wrapping shielding layer; and four tensile ropes are arranged in the flame-retardant filling layer. With the adoption of the mode, the network cable has a good tensile property, a flame retardance property, a fire resistance property and a shielding property.
Description
Technical field
The present invention relates to technical field of cables, particularly relate to a kind of network cable.
Background technology
Network cable, is again network connection, is for example, from a network equipment (computer, router), to be connected to the medium of another one network equipment transmission of information, and be the basic building block of network.
Network cable can be subject to larger pulling force in wiring installation process, and the tensile property of existing network cable is not good; Existing network cable is also needing further improvement aspect fire protection flame retarding and shielding properties in addition.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of network cable, has good tensile property, fire-retardant fireproof performance and shielding properties.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of network cable is provided, comprise: four strands of twisted-pair feeders, be arranged on the metal tape lapped shielding layer of four bursts of twisted-pair feeder outsides and be arranged on the external sheath layer of described metal tape lapped shielding layer outside, between described four strands of twisted-pair feeders and metal lapped shielding layer, be provided with fire-retardant packed layer, in described fire-retardant packed layer, be provided with four tension ropes.
In a preferred embodiment of the present invention, described fire-retardant packed layer is glass fibre packed layer.
In a preferred embodiment of the present invention, described tension rope adopts many aramid fiber composite twists to form.
In a preferred embodiment of the present invention, between described metal tape lapped shielding layer and external sheath layer, be also provided with mica belt.
The invention has the beneficial effects as follows: network cable of the present invention, has good tensile property, fire-retardant fireproof performance and shielding properties.
