High-flame-retardant data cable

Abstract

The invention discloses a high-flame-retardant data cable comprising a flame-retardant protective outer sleeve and a cable assembly. The flame-retardant protective outer sleeve comprises an outer skinlayer, a flame retardant layer, an isolation layer and a woven layer; the flame retardant layer is sleeved with the outer skin layer; the isolation layer is sleeved with the flame retardant layer; the woven layer is sleeved with the isolation layer; and a storage cavity is formed in the woven layer. The cable assembly comprises a plurality of data transmission cables, and the multiple data transmission cables are stored in the storage cavity and comprise insulation layers, shielding pipe sleeves, foam glue, grounding wires, power supply positive wires, first data cable bodies and second datacable bodies. According to the high-flame-retardant data cable, by arranging the flame retardant layer, it is guaranteed that during a fire, a communication assembly in the cable is not burned, it isguaranteed that the outer skin layer has good flame retardance during a fire behavior, the amount of generated smoke is small, toxicity is weak, it is guaranteed that the visibility of a fire behaviorarea is increased when personnel are dense, and the situation of dying from suffocation due to the excessive smoke is reduced.

Description

technical field [0001] The invention relates to the field of data cables, in particular to a high flame-retardant data cable. Background technique [0002] Data cables are mainly divided into two types: one is the 100Ω cable promoted in the Americas, mainly for unshielded twisted-pair cables; the other is the 150Ω cable promoted in Europe, mainly for shielded twisted-pair cables. With the rapid development of optical communication technology, optical cables have been widely used in the backbone network and inter-office relay lines of my country's wired communication network, and it has become an inevitable trend for optical fibers to enter the access network. However, the cost of laying optical cables is too high, and the cost of joints and terminal optical-electrical conversion is expensive. Therefore, for a long time before the popularization of optical fiber, the subscriber lines of the access network will still be dominated by metal cables. Metal cables mainly include p...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a high flame-retardant data cable. By setting a flame-retardant layer, it is ensured that the internal communication components of the cable will not be burned when a fire occurs, and that the internal communication components of the cable are not burned when a fire occurs. The outer skin layer has good flame retardancy, the amount of smoke produced is small and the toxicity is weak, ensuring that the visibility of the fire area is improved when people are crowded, and the situation of suffocation and death caused by excessive smoke is reduced
