Abstract

The invention discloses a light power communication fireproof cable and a preparation method thereof. The light power communication fireproof cable comprises a carbon fiber / glass fiber optical fiber composite core rod (7), a special-shaped conductor (9) wrapped on the periphery of the carbon fiber / glass fiber optical fiber composite core rod (7), an insulating tape (10) wrapped on the outer layerof the special-shaped conductor (9), a wrapping tape (11) wrapped on the outer layer of the insulating tape (10) in a winding manner, and a seamless embossing tube (12) wrapped on the outer layer of the wrapping tape (11), wherein the carbon fiber / glass fiber optical fiber composite core rod (7) has a single-core rod structure or a multi-core rod structure. The light power communication fireproofcable of the invention has the functions of fireproof power transmission, fireproof optical path communication, line temperature sensing and the like. In addition, the light power communication fireproof cable also has the characteristics of flame retardance, fire resistance, low smoke, no halogen, light weight, aging resistance, excellent mechanical property and the like. The preparation method of the light power communication fireproof cable adopts the combination of a pultrusion process, a cabling process, an armoring process, an extrusion molding process and the like, thus reasonable process design is achieved, and the preparation method can be used for industrial production.

Description

technical field [0001] The invention relates to a communication cable, in particular to a light electric communication fireproof cable and a preparation method thereof. Background technique [0002] Power communication cable products are responsible for the transmission of electric energy, important data, images and other information in the safety system of buildings and equipment engineering, because at present, cable products often play a role in combustion and even release poisonous gas in a fire, which endangers people's lives and property safety issues, and bring irreparable losses and negative impacts. According to statistics, because electrical lines catch fire in crowded places, high-rise important buildings, office buildings, etc., the occurrence of building fires caused has caused huge losses to the people. In view of the concealment of cables in fire, the spread of combustion, and the toxicity of combustion smoke, the relevant departments of fire protection and a...
