Problems solved by technology

[0002] Although the existing digital communication cables are relatively convenient to install and install, when they are used in places with high-intensity electromagnetic waves and laboratories with precision instruments, the radiation of electromagnetic waves will cause damage to the cable itself and the equipment and networks around the cable. Severe interference, coupled with the conventionally used PVC sheath material, the fire prevention effect is not ideal, and a large amount of toxic and harmful gases and smoke will be generated during combustion, which directly endangers the life safety of the staff

Embodiment Construction

[0006] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0007] Such as figure 1 As shown, the present invention discloses a digital communication cable, including a cable core, a shielding layer, and a sheath. The cable core includes four pairs of twisted wires, and each pair of twisted wires is formed by twisting two single wires 1. The single wire 1 includes a copper wire core 11 and a polyethylene insulating layer 12 coated on the outside of the copper wire core 11; the sheath includes an inner sheath 2 and an outer sheath 3, and the inner sheath 2 and the outer sheath The sheaths 3 are extruded sheaths made of low-smoke, halogen-free, environmentally friendly and flame-retardant materials. Holes are arranged inside the inner sheath 2, and the holes are used to accommodate the cable core. The outer sheath 3 is wrapped in The o...

Abstract

The invention discloses a digital communication cable which comprises a cable core, a shielding layer and a sheath. The cable core comprises four sets of twisted pair wires. Each set of twisted pair wires is obtained through winding two single wires (1). The single wire (1) comprises a copper conductor core (11) and a polyethylene insulating layer (12). The sheath comprises an inner sheath (2) and an outer sheath (3). The inner sheath and the outer sheath are formed through squeezing a low-smoke halogen-free environment-friendly flame-retardant material. The inner sheath (2) is internally provided with a hole for accommodating the cable core. The outer sheath (3) packages the shielding layer (4). Furthermore a tinned copper wire (5) is arranged between the inner sheath (2) and the outer sheath (3). The shielding layer (4) packages the inner sheath (2) and the tinned copper wire (5).

Description

technical field [0001] The invention relates to a cable, in particular to a digital communication cable. Background technique [0002] Although the existing digital communication cables are relatively convenient to install and install, when they are used in places with high-intensity electromagnetic waves and laboratories with precision instruments, the radiation of electromagnetic waves will cause damage to the cable itself and the equipment and networks around the cable. Severe interference, coupled with the conventionally used PVC sheath material, has an unsatisfactory fireproof effect, and a large amount of toxic and harmful gases and dense smoke will be generated during combustion, which directly endangers the safety of workers. Contents of the invention [0003] In view of the above technical problems, the present invention discloses a digital communication cable, including a cable core, a shielding layer, and a sheath. The cable core includes four pairs of twisted w...
