Description

An aramid fiber reinforced cable

technical field

The utility model relates to a cable, in particular to a high-strength cable.

Background technique

Domestic rubber winding cables are subject to various mechanical stresses such as frequent bending and stretching during operation, which can easily lead to core breakage. Once the core is broken, the entire production line will stop production, causing great losses to users.

According to on-site tracking and sampling analysis, the cable is frequently subjected to the combined effects of two or more stresses such as excessive bending and stretching for a long time. If it is a conductor with a small cross-section, it is easier to break the core. It is common for the wire core of the cable to break easily, resulting in that the service life of the cable generally cannot meet the requirements of the production site. Although the service life of imported shearer cables is higher than that of domestic cables, it is generally about half a year. On the other hand, imported cables have the disadvantage of high product prices.

Contents of the invention

Purpose of the invention: The purpose of this utility model is to overcome the deficiencies in the prior art and provide an aramid fiber-reinforced cable that improves the overall strength of the cable and improves the service life of the product.

Technical solution: In order to solve the above technical problems, an aramid fiber-reinforced cable described in the utility model includes a conductor formed by twisting wire bundles, and aramid fiber filaments are evenly arranged in the conductor, and in the An inner semi-conductive tape layer is provided outside the conductor, a semi-conductive shielding layer is provided outside the inner semi-conductive tape layer, an insulating layer is provided outside the semi-conductive shielding layer, and a semi-conductive shielding layer is provided outside the insulating layer. The conductive insulating shielding layer is provided with an outer semiconductive tape layer outside the semiconductive insulating shield layer, and a braided layer of copper wire aramid fiber wire is arranged outside the outer semiconductive tape layer, and the copper wire aramid fiber wire The braiding layer is made of copper wire and aramid fiber wire according to 2 stacks of vertical weaving, a filling layer is provided outside the braiding layer of copper wire and aramid fiber wire, and a braiding layer of aramid fiber wire is provided outside the filling layer , an outer sheath layer is provided outside the braided layer of aramid fibers.

The wire bundles are tinned copper wire bundles.

There are two conductors.

The insulating layer is an EPR insulating layer.

The filling layer is a semiconducting filling layer.

The outer sheath layer is a CPE sheath layer.

Beneficial effects: Compared with the prior art, the utility model has the remarkable advantages that: the utility model has a reasonable structure setting, uses aramid fiber strands to twist in the conductor, and allows the aramid fiber strands to carry some force, which can reduce the conductor copper. The stress of the wire can improve the tensile and bending resistance of the conductor. The copper wire aramid fiber braid and the aramid fiber braid are used to further improve the overall strength of the cable. The aramid fiber braid and the outer sheath layer It is formed by double-layer co-extrusion, one-time molding, reinforced in place, and the outer sheath layer has a good protective effect. This product has a long service life and meets the actual use requirements.
