Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable containing a recyclable covering. Background Art

[0002] At present, cables are usually rope-like cables composed of several or several groups of wires, each group of at least two wires twisted together. Each group of wires is insulated from each other and often twisted around a center. Low-voltage cable is a commonly used cable. Its main purpose is to connect the conductors of low-voltage power supplies and equipment, so that the equipment can obtain power through the cable to do work, as well as control cables, communication cables, signal cables, etc.

[0003] The prior art has an environmentally friendly cable with an authorization announcement number of CN212084716U. This patent relates to the field of cable technology and discloses an environmentally friendly cable, which includes at least two cable cores, each of which is composed of a conductor, a fire-resistant layer and a polypropylene insulation layer from the inside to the outside. The cable core is wrapped with a wrapped fire-resistant layer and a flame-retardant filling layer to enhance the flame retardant performance of the cable. A ceramic fire-resistant layer and a flame-retardant sheath layer are stacked in sequence outside the wrapped fire-resistant layer to improve the temperature resistance level and current carrying capacity of the cable. The patented design aims to provide the advantages of high temperature resistance, large current carrying capacity, excellent flame retardant performance and an environmentally friendly insulation layer.

[0004] However, this patent improves the thermal insulation and flame retardant properties of the cable, but when in use, the cable does not have strong strength and poor tensile strength, making the cable less protective;

[0005] When connecting two cables in the traditional way, the cables need to be held by hand and then fixed and sealed with a clamp, which is inconvenient and less practical.

[0006] In the prior art, the patent publication number is CN1229821C, which is a cable with a recyclable covering. The patent relates to a cable specially used for transmitting or distributing medium and high voltage energy. The cable is characterized in that a recyclable covering is used. At least one layer of the covering is made of a mixture of a thermoplastic polymer material and a dielectric liquid. The polymer material includes a propylene homopolymer or a copolymer with ethylene and α-olefin (non-propylene). The patent has excellent mechanical and electrical properties, especially high dielectric strength, so that it can operate stably in a high temperature operating environment.

[0007] However, this patent can improve the mechanical and electrical properties of the cable, allowing it to be used at high temperatures, but it has poor practicality, strength, and protection performance, which affects long-term use. Utility Model Content
