Multi-scene flame-retardant photoelectric composite cable

Abstract

The invention discloses a multi-scene flame-retardant photoelectric composite cable which comprises a first outer sheath, a fireproof layer, a first waterproof layer, a second outer sheath, a reinforcing layer, a second waterproof layer and a cable core. The first outer sheath, the fireproof layer, the first waterproof layer, the second outer sheath, the reinforcing layer and the second waterproof layer are sequentially arranged on the outer side of the cable core from outside to inside. According to the invention, the two layers of outer sheaths, the photoelectric composite cable core and the outer sheath of a butterfly-shaped optical cable form a three-layer sheath protection structure, and meanwhile, the fireproof layer is added, so that photoelectric signals can be transmitted in fire-prone areas, and the safety of the product is greatly improved.

Description

technical field [0001] The invention relates to a photoelectric composite cable, in particular to a multi-scene flame-retardant photoelectric composite cable, which belongs to the field of photoelectric composite cables. Background technique [0002] With the promotion of optical fiber and cable business, more and more manufacturers are not limited to the transmission of optical signals. Various construction scenarios, and the construction is convenient and simple. Most of the photoelectric composite cables currently on the market simply integrate the original cables and optical cables into a photoelectric composite cable by adding an outer sheath for use. The main problems are as follows: 1. The fire rating is low, and it cannot cope with fire hazards 2. In areas such as mountains, forests, and northern regions with a low climate (permafrost), the transmission of optical signals and electrical signals is simply divided into two products, which greatly reduces construction ...

Most of the photoelectric composite cables currently on the market simply integrate the original cables and optical cables into a photoelectric composite cable by adding an outer sheath for use. The main problems are as follows: 1. The fire rating is low, and it cannot cope with fire hazards 2. In areas such as mountains, forests, and northern regions with a low climate (permafrost), the transmission of optical signals and electrical signals is simply divided into two products, which greatly reduces construction efficiency; 3 , Low strength, poor tensile and compressive properties, unable to meet the requirements of high temperature resistance and low temperature resistance; 4, unable to achieve the ability to apply indoor and outdoor scenes at the same time
