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.; traditional Ethernet cables generally have a cable core plus a layer of PVC sheath, or a PVC inner sheath plus a polyethylene outer sheath. This traditional form of cable has load-bearing defects when wiring outdoors and buried, and even affects the performance of its key parameters. In the traditional concept, Ethernet cables cannot be used directly outdoors or buried. Therefore, the traditional Generally, Ethernet cables are used directly through steel pipes or plastic pipes and overhead steel wires for load-bearing use, and cannot be directly buried, especially in some harsh environments.

Embodiment 1

[0016] Example 1 : see figure 1 , a Category 5e unshielded double-sheathed armored symmetrical data cable for Ethernet, the symmetrical data cable includes a core outer sheath 8, a non-woven fabric layer 7, a double-layer inner sheath and a There are four sets of cable cores inside the double-layer inner sheath, and a steel wire armor layer 6 is arranged between the non-woven fabric layer 7 and the double-layer inner sheath. It can effectively improve the possibility of harsh environments and communication data cables being buried in the ground. The double sheath plus steel wire armor and then sheath improves the load-bearing capacity and direct burial of communication data cables. It is easy to use and simple to lay.

Embodiment 2

[0017] Example 2 : see figure 1 , as an improvement of the present invention, the double inner sheath includes a first inner sheath 4 and a second inner sheath 5 from the inside to the outside. In this technical solution, a double-layer inner sheath is provided to improve the adaptability of the cable to harsh environments. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Embodiment 3

[0018] Example 3 : see figure 1 , as an improvement of the present invention, the first inner sheath is provided with a tearing rope 3 to enhance the tensile performance of the cable. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Abstract

The invention relates to a category-5-enhanced non-shielded dual-sheath armoured symmetric data cable used for the Ethernet. The symmetric data cable is characterized by comprising a core body outer sheath, a non-woven fabric layer, dual layers of inner sheaths and four groups of cable cores arranged in the dual layers of inner sheaths from outside to inside, wherein a steel wire armoured layer is arranged between the non-woven fabric layer and the dual layers of inner sheaths. According to the scheme, the dual-layer sheaths and the steel wire armoured layer are arranged, so that the probability of embedding the communication data cable underground in a severe environment can be effectively improved; due to the double sheaths and the steel wire armoured layer, the bearing capacity and the compression resistance of the communication data cable are improved; and meanwhile, the cable is convenient to use and simple to lay.

Description

technical field [0001] The invention relates to a cable, in particular to a category five super unshielded double-sheathed armored symmetrical data cable for Ethernet, and belongs 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.; traditional Ethernet cables generally have a cab...
