A fire-resistant computer cable

Abstract

The invention discloses a fireproof computer cable. The fireproof computer cable comprises a central conductor. The central conductor is composed of at least two central insulated cable core sets, first fireproof layers wrapping the central insulated cable core sets and first flame-resistant materials filling the portions between the central insulated cable core sets and the first fireproof layers. Outer conductors are sequentially and uniformly distributed outside the first fireproof layers. Third fireproof layers, fiber rope braiding layers and outer sheath layers sequentially wrap the outer conductors. Third flame-resistant materials fill the gaps between the outer conductors and the first fireproof layers as well as between the outer conductors and the third fireproof layers. The outer conductors are vertically arranged in the third fireproof layers in parallel, and the two ends of the short axes of the outer conductors are close to the first fireproof layers and the third fireproof layers respectively. The fire resistance and the high temperature resistance of the computer cable are greatly improved, the insulation aging risk of the computer cable is lowered, and the normal electrification and use time of the computer cable under the fire disaster condition can be prolonged as long as possible.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a fire-resistant computer cable. Background technique [0002] With the continuous development of my country's economy, the demand for fire-resistant computer cables in civil and industrial facilities such as large buildings, underground streets, large power stations, and modern industrial and mining enterprises is also increasing. Traditional fire-resistant computer cables use conductors to directly cover refractory materials. When exposed to open flames and heated for a long time, the refractory materials will shrink and fall off, which will not only pollute the environment but also damage the health of production workers. Moreover, the design of traditional fire-resistant computer cables cannot allow the cables to It has high fire resistance and high heat resistance. [0003] The invention with the publication number CN102820091A disclosed a fire-resistant computer c...

Problems solved by technology

In this way, when the computer cable encounters an open flame, the refractory layer cannot maintain the cable work for the maximum time, and cannot provide valuable time for people to escape from the fire as long as possible.
