Abstract

The invention relates to the technical field of cables and particularly to a high-strength fireproof cable comprising a first sheath in which a plurality of conductors are disposed. The outside of each conductor is successively provided with an insulating sleeve, a metal sleeve and an isolating sleeve. Four arc support plates are disposed in the first sheath at intervals. A plurality of conductors are uniformly distributed in the four arc support plates. Gaps between the conductors and the arc support plates are filled with an oxygen isolation material. Gaps outside the four arc support plates are filled with a mineral substance fire isolation material. The first sheath is further provided with a support strip therein located among the four arc support plates. The outside of the first sheath is sleeved by a second sheath. The high-strength fireproof cable is simple in structure and convenient to use, and has not only high strength, but also a good fireproof effect.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-strength fireproof cable. Background technique [0002] At present, people's need for fast transmission of data and information, and their dependence on computers, word processors, telex, sensors and communication equipment have increased significantly and rapidly. The emergence of new technologies has made it possible to connect and network equipment in this area, leading to the comprehensive development of communication systems. The use of these systems has increased in specific areas such as high-rise buildings, ships, aircraft, trains, drilling platforms and mines. In order to connect these electronic components, a large number of wires and cables are used in these structures and fields. [0003] The cable will be frequently punched and twisted during laying and use, and dragged for a long time, the wire core is prone to breakage, which will easily lead to the breakag...
