Embodiment Construction

[0015] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments, and the described embodiments are only some of the embodiments of the present invention, not all of them.

[0016] Such as figure 1 As shown, a moisture-proof and flame-retardant communication cable of the present invention includes a three-core cable 1 and an outer sheath 2 wrapped outside the three-core cable. The cable 1 includes a conductor 11 and an insulating layer 12. The insulating layer of the cable 1 12 is wrapped with a refractory mica wrapping tape, and a water-blocking rope is filled between the three-core cable 1 and the outer sheath 2 .

[0017] Furthermore, a fire-resistant mica wrapping tape or a water-blocking wrapping tape is wrapped between the water-blocking rope and the outer sheath 2; the water-blocking wrapping tape is made of a polymer material.

[0018] Furthermore, the outer she...

Abstract

The invention discloses a moisture-proof and flame-retardant communication cable, which comprises a three-core cable and an outer sheath wrapped outside the three-core cable, the cable includes a conductor and an insulating layer, and the insulating layer of the cable is wrapped with fire-resistant mica wrapping The water-blocking rope is filled between the three-core cable and the outer sheath. The invention has very good water-repelling and moisture-proof properties, and also has very good flame-retardant effect.

Description

technical field [0001] The invention relates to the field of cables, in particular to a moisture-proof and flame-retardant communication cable. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Insulating covering. Most of them are erected in the air or installed underground or underwater for telecommunications or power transmission. In 1832, Schlinger, a retired military officer from Tsarist Russia, buried the telegraph line underground. The six wires were insulated with rubber and placed in a glass tube together. This is the earliest underground cable in the world. [0003] An insulated wire consisting of one or more mutually insulated conductive cores placed in a sealed sheath. A protective covering can be added to the outside for transmission, distribution of electrical energy or transmiss...
