Cable with flame-retardant and water-blocking functions

Abstract

The invention provides a cable with flame-retardant and water-blocking functions and belongs to the technical field of cables. The cable comprises an outer protective layer, an inner sheath and conductors. The inner sheath is fixedly connected to the interior of the outer protective layer; the conductors are uniformly distributed at the inner end of the inner sheath; one side of the inner sheath is fixedly connected with sponge filler, one side of the sponge filler is connected with a corresponding conductor, fixing sol is evenly distributed in the outer sheath, one end of each fixing sol is fixedly connected with an arc-shaped water-blocking tape, and each water-blocking tape is connected with each fixing sol in a bonding mode. The cable with the flame-retardant and water-blocking functions is stable in structure. so that external moisture can be prevented from directly entering the interior of the cable, the interior of the cable is isolated from the external moisture, the interior of the cable is prevented from being affected with damp, and meanwhile, each water-blocking tape is connected with each fixing sol in a bonding manner, so that the retention tightness of the water-blocking tape in the cable can be improved, and the overall use quality of the cable is improved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable with flame-retardant and water-resistant functions. Background technique [0002] The cable is usually composed of several or several groups of wires, made of one or more mutually insulated conductors and an outer insulating protective layer, which transmits power or information from one place to another. The system can be divided into DC cables and AC cables, which are classified according to different uses and environments. [0003] However, the existing cables lack effective flame retardancy in actual use, and may burn the skin of workers due to the high temperature of the cable body, and the existing cables have poor water resistance, which easily makes the inside of the cable wet due to ambient humidity. [0004] Therefore, it is necessary to upgrade and transform the existing cables to overcome existing problems and deficiencies. Contents of the invention [0005...

Problems solved by technology

[0005] The present invention aims to solve the problem that the existing cables lack effective flame retardancy during actual use, and may burn the skin of the staff due to the high temperature of the cable body, and the existing cables have poor water resistance function, which easily makes the inside of the cable wet due to environmental humidity To solve this problem, provide a cable with flame-retardant and water-resistant functions. By setting flame-retardant sleeves, water-blocking tapes, fixing sols, and thickening layers, the structure of the device is stable, and it can block external moisture from directly entering the interior of the cable, making the interior of the cable It is isolated from external moisture to avoid moisture inside the cable. At the same time, since the water-blocking tape is connected to the fixed sol by bonding, the tightness of the water-blocking tape retained inside the cable can be improved, and the overall quality of use of the cable can be improved.
