Abstract

The invention discloses a multifunctional fireproof communication cable and an armor layer installation process thereof. The cable comprises an insulating sheath, an armor layer located in the insulating sheath, a silicone rubber sleeve located in the armor layer, power cables, control wire cores, and a mineral insulating layer located in the silicone rubber sleeve and used for filling gaps, wherein the armor layer comprises a plurality of equally spaced steel rings which sleeve the silicon rubber sleeve in the axial direction of the silicon rubber sleeve, and a protective layer formed by a steel belt wrapped outside a steel sleeve; the space between every two adjacent steel rings is filled with a silicone rubber insulating layer; and the inner wall of the protective layer abuts against the outer walls of the steel rings. According to the scheme, the armor layer is provided with the steel rings and the steel belt in a wrapping mode; because of the existence of the steel belt, the anti-pressure capability is effectively improved; as the steel bet is wrapped and the steel rings are high in pressure resistance, the steel belt is not liable to stretch, and the overall tensile resistance of the cable is high, while steel belts of traditional cables which only comprise silicone rubber sleeves are liable to stretch and deform and low in tensile resistance due to radial deformation ofsilicone rubber sleeves.

Description

technical field [0001] The invention relates to the field of cables, in particular to a multifunctional fireproof communication cable and an installation process for an armor layer thereof. Background technique [0002] The armored communication cable mechanical protection layer can be added to the cable of any structure to increase the mechanical strength of the cable and improve the corrosion resistance. It is a telephone cable designed for areas that are susceptible to mechanical damage and erosion. It can be laid in any way, and it is more suitable for direct burial laying in rocky areas. [0003] The present cable structure is as disclosed in CN101174495A, a kind of armored data cable, comprises cable core and PVC sheath, is characterized in that, is provided with insulating layer outside each cable core, and PVC sheath is located at with insulating layer Outside the cable core, an armored stainless steel strip is wound horizontally outside the PVC sheath, and a copper...
