Abstract

The invention discloses a fireproof cable, and relates to the technical field of cables, in particular to fireproof cables. The fireproof cable comprises five conductive wire cables, and a second mica wrapping layer, an outer glass fiber layer and a shield layer are sequentially arranged outside the stranded conductive wire cables. Each conductive wire cable comprises a copper wire bundle conductor, and an inner fiber layer and a first mica wrapping layer are sequentially wrapped outside each copper wire bundle conductor. Filler is arranged between the first mica wrapping layer and the second mica wrapping layer. The fireproof cable is applicable to the environment at the high temperature ranging from 500 DEG C to 800 DEG C, is good in fireproof performance and stability, high in safety, capable of meeting fireproof and fire-resistant performances required by modern construction and applicable to wires and cables applied in various waterproof devices of oil, chemical industry and high-temperature furnaces and the like.

Description

Technical field [0001] The invention relates to the technical field of cables, in particular to the technical field of fire-resistant cables. Background technique [0002] In order to improve the safety level of electrical circuits, the flame-retardant and fire-resistant problems of cables have attracted more and more attention. However, no matter what kind of fire occurs, it is very important to maintain the operating state of the main electrical equipment and provide continuous power supply and control. Importantly, power supply lines such as oil production platforms, petrochemical companies, and large power stations must use fire-resistant cables to reduce losses caused by fires. At present, the general fire-resistant cable manufacturing process is complicated and the fire-resistant performance is unstable, which cannot meet the fire-resistant and fire-resistant performance requirements required for modernization. Summary of the invention [0003] The purpose of the present in...
