Category 6 shielding armoured symmetric data cable used for Ethernet

Abstract

The invention relates to a category 6 shielding armoured symmetric data cable used for an Ethernet. The cable is characterized in that the symmetric data cable comprises a core body outer sheath, a non-woven fabric layer, a steel wire armoured layer, a double-layer inner sheath and four groups of cable cores arranged in the inner sheath, which are arranged from outside to inside. The double-layer inner sheath comprises a first inner sheath and a second inner sheath, and the first inner sheath and the second inner sheath are arranged between the steel wire armoured layer and the cable cores. According to the scheme, the steel wire armoured layer and the double-layer inner sheath layer are arranged, the possibility of the communication data cable to be used in a severe environment and the possibility of burying of the communication data cable are effectively improved, and the bearing capability and the electromagnetic interference resistance of the communication data cable are improved.

Description

technical field [0001] The invention relates to a cable, in particular to a six-category shielded and armored symmetrical data cable for Ethernet, belonging to the technical field of communication cables. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires. Each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating covering. The cable has the characteristics of internal electrification and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. Composed of multi-strand wires and insulating layers, it is used to connect circuits, electrical appliances, etc.; with the rapid development of information technology, people have highe...

Problems solved by technology

Cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. Composed of multi-strand wires and insulating layers, it is used to connect circuits, electrical appliances, etc.; with the rapid development of information technology, people have higher and higher requirements for network speed. With the development of cloud computing and big data, the widely used six Such unshielded wiring systems can no longer meet some higher requirements when used in buried ground, especially when Ethernet is used in buried ground, it is required to be able to withstand pressure and waterproof, and when used in harsh environments, the characteristic parameters of data cables are prone to instability. : Near-end crosstalk interference. The unshielded structure used in the prior art is not enough to prevent external electromagnetic radiation from entering the cable. In harsh environments, traditional network cable wiring generally adopts pipe-pipe wiring instead of direct buried use, and cannot Load-bearing and tensile, and with the increase of network speed and frequency, the interference of the environment on the cable is increasing. These factors have become the main factors affecting the transmission effect of the cable. Therefore, a new solution is urgently needed to solve this technical problem.
