Problems solved by technology

[0002] At present, cables are widely used in power, communication and related transmission projects. They are usually rope-like cables made of several or several groups of wires twisted with at least two wires in each group. Each group of wires is insulated from each other and often wrapped around It is twisted around a center, and the entire outer surface is covered with a highly insulating covering layer. The durability of ordinary cables is poor, and the strength needs to be strengthened.
Although the existing cables made of improved materials have been greatly improved in strength, their cost is relatively high.

Abstract

The invention provides a high strength cable. The cable comprises a cable core and a protection sleeve layer; the cable core comprises a conductor located in the middle part and an insulation layer coating the conductor; the protection sleeve layer is arranged out of the cable core; the protection sleeve layer comprises an internal protection sleeve layer and an external protection sleeve layer; the internal protection sleeve layer is located between the external protection sleeve layer and the insulation layer; the internal protection sleeve layer is made of a fiber material; the external protection sleeve layer is made of a modified natural rubber material. The modified natural rubber material has excellent crack growth prevention performance, tensile strength and tearing strength; through using the modified natural rubber material to make the external protection sleeve layer of the cable, the strength of the cable is improved, and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of cable equipment, in particular to a high-strength cable. Background technique [0002] At present, cables are widely used in power, communication and related transmission projects. They are usually rope-like cables twisted by several or several groups of wires, each of which is twisted with at least two wires. Each group of wires is insulated from each other and often wrapped around It is twisted around a center, and the entire outer surface is covered with a highly insulating covering layer. The durability of ordinary cables is poor, and the strength needs to be strengthened. However, although the strength of the cables prepared by the existing improved materials is greatly improved, the cost is relatively high. Therefore, it is necessary to design a high-strength, low-cost cable. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a ...
